They contains a 200 W metal halide lamp and associated optics to deliver bright illumination from 340 nm to 650 nm (PhotoFluor II) or 360 nm to 850 nm (PhotoFluor II NIR). The illumination is directed to the microscope via a liquid light guide (LLG). The light guide limits heat delivery to the microscope and provides flexibility in the placement of the main body of the light source. The light source supports both 3mm and 5mm core diameter liquid light guides.Both the PhotoFluor II and PhotoFluor II NIR use specific light guides to maximize the output in their intended transmission bands. Using the incorrect liquid light guide will compromise the performance of the light engine and prematurely age the light guide.The metal halide lamp used will operate for greater than 1500 hours of use. The light source will report the number of hours of use on the display panel.Because of its intense brightness, the light source includes an electronic motor driven neutral density filtering device that allows the user to attenuate the light that is delivered to the microscope. The amount of light that is being transmitted through the system is reported on the display.Only the lamp and Light Guide supplied by the manufacturer shall be used. The use of other products may impair the safe operation and protections provided by the equipment.2SafetyThe PhotoFluor II family of light sources uses a powerful lamp that produces heat as well as visible, UV light and NIR light (PhotoFluor II NIR). Proper care must be taken in the setup and operation to prevent injury.If the equipment is used in a manner notspecified within this manual the protectionprovided by the equipment may be impaired.Never open or remove the top cover. Allmaintenance, including lamp replacement,must be performed by qualified personnel only.The lamp contains trace amounts of mercuryand other metals. If the lamp is damaged orbroken, proper handling and disposal arerequired for safety.Do not operate the unit near any flammablematerials including flammable gases or liquids.The light source is designed to sustain a bulbburst within the light engine enclosure. Thelight source may, however, suffer internaldamage as a result. Only qualified personnelshall inspect the unit for internal damage.WARNING: Inhaling mercury vapor or small particles of mercury or its compounds can be harmful to lungs, kidneys, and the nervous system. Injuries to one’s health can also arise due to penetration of the skin or resorption via the gastro-enteric tract.WARNING: To prevent risk of explosion:∙ Replace lamp after 1500 hours of use with the required bulb only∙ Do not bump the unit while in use∙ Do not touch any portion of the bulb except the ceramic base and power wires as improper handling may shorten bulb life and may lead to catastrophic failure of the lamp. WARNING: The lamp produces significant amounts of ultraviolet radiation. Never look directly at the lamp or at light reflected from the lamp or the output from the liquid light guide.WARNING:Never operate the lamp with the light guide disconnected from the microscope as ultraviolet and NIR radiation can be harmful to the unprotected eye and skin.WARNING:LAMP EXPLOSION HAZARD - The lamp contains toxic gasses under high pressure. Inthe event of an explosion, mercury vapor, high temperature gasses, and very fine glass may exit the unit.All persons should leave the surrounding area at once to prevent mercury inhalation.The area should be ventilated for 30 minutes.The area surrounding the light source should be cleaned using an appropriate absorbent such as Mercurisorb® or Mercon™ Mercury Spill Kit II or Mercury Spill Clean-Up Kit.WARNING: The lamp produces significant amounts of heat.Always allow the light source components tocool to ambient temperature before attemptingany adjustments or replacement of parts. WARNING:After 1500 hours of operation, the metal halidelamp must be replaced to ensure suitableperformance and safety. The light source willalert the user at 1500 hours that the lamp is duefor replacement. At 1600 hours, the light enginewill cease operation as the bulb is no longer safeto use.WARNING:Used lamps should not be discarded in theconventional waste stream. The lamps containmetals that must be handled as potentially toxic.3 System OverviewFront Panel Controls:Rear Panel:Safety Interlock:4 Initial SetupSystem ComponentsThe PhotoFluor II and PhotoFluor II NIR illumination systems are comprised of:▪Light Source▪Liquid Light Guide (specific to both the PhotoFluor II and the PhotoFluor II NIR)▪Microscope Adapter (as required)▪Electrical Power Cord▪USB to Serial adapter▪BulbCarefully unpack all components, giving particular care to the liquid light guide. The light guide should never be bent severely or it will sustain irreversible damage. Also take care not to touch or contaminate the ends of light guide. If necessary the ends can be cleaned with isopropyl alcohol and a soft cloth.Picking a LocationSet the light source on a flat surface in a place that allows for adequate air ventilation on all sides. Do not position the unit so that any of the sides (including the back or the top) are up against a wall or other equipment.NOTE: Maintain at least 6” of clearance around all sides of the light source for adequate ventilation.Light Guide ConnectionPush the wider end of the light guide into the acceptor at the back of the unit until it snaps in place. Do not force the light guide.Using an Allen wrench, attach the adapter (as required) to the epi-illumination port of the microscope. Insert the end of the light guide and secure in place by turning the red knob firmly to the right.Connecting the Power CordInsert the power cord receptacle end into the AC receptacle in the back of the unit. Insert the power cord plug end into a standard AC outlet. See the technical bulletin in this manual for power requirements.Turning the Unit “ON” Using Rear Panel SwitchActivate the main power switch in the back of the unit next to the AC receptacle. Your unit should then power on the lamp. After three to six minutes the lamp should be fully warmed up and ready for use.To avoid damage to the lamp DO NOT turn thelamp off in the first three minutes while it iswarming up.NOTE: Avoid turning off and restarting the bulb during daily use unless it will not be used for an extended time. Bulb life is shortened by excessive restarts. For typical daily use it is best to let it run.NOTE: This equipment has passed testing for EMI / RFI radiation and susceptibility; however, if not installed and used in accordance with the instructions, interference to other devices in the near vicinity may occur. If this equipment does cause harmful interference to other devices, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures.▪Reorient or relocate the receiving device.▪Increase the separation between the equipment.▪Connect the equipment into an outlet on a circuit different from that to which the other device(s) are connected.▪Consult the manufacturer or field service technician for help.5Adapters and Liquid Light GuidesThe PhotoFluor II and PhotoFluor II NIR light sources have adapters available for a wide arrange lf microscope and imaging systems. Contact 89 North or an authorized 89 North reseller for more information.Two different diameter liquid light guides are available. The PhotoFluor II and PhotoFluor II NIR each use different LLGs to maximize their specified transmission range. Use of the wrong LLG will both comprise the output power of the system and result in premature light guide aging. Only use the LLG specified for your version of PhotoFluor II.Neutral Density ControlThe PhotoFluor II and PhotoFluor II NIR, as shipped, have five levels of internal attenuation for the lamp output. The level of attenuation is adjusted by either the front panel controls or through optional external software. An internal electronic drive system moves the filters into position as well as actuates the light shutter feature.Position Transmission1 100%2 75%3 60%4 40%5 20%6 ClosedThe ◄ and ► arrows on the keypad step the filters in the Main Screen (Normal Mode).

And only four HP E1510s can be installed in an HP E1313A.Manual Part Number: E1510-90002Printed: October 1996 Edition 2E1510-90002Copyright © Hewlett-Packard Company, 1994, 1995, 1996HP E1510Four-Channel Sample and HoldSignal Conditioning Plug-on IntroductionHP E1510 is a Signal Conditioning Plug-on (SCP) that provides 4channels of Sample and Hold inputs and 4 channels of direct inputs for theHP E1413 High Speed A/D Module.Notes 1. The HP E1510, 4 Channel Sample and Hold SCP can only be usedwith the HP E1313A and HP E1413B/E1413C 64-Channel HighSpeeed Scanning A/D and not with a model E1413A 64-ChannelHigh Speed A/D (flash version 4.0 or above; downloadable driverversion 6.0 or above ).2. The HP E1313A B-size 32/64-Channel High Speeed Scanning A/Dcan only support a maximum of four (4) HP E1510A 4-ChannelSample and Hold SCPs.About This ManualExcept where noted, references to the HP E1413 also apply to theHP E1313.This manual shows how to connect to the Terminal Module andalso shows how to control the HP E1510 Signal Conditioning Plug-on(SCP) using SCPI commands and Register-Based commands.

The sample and hold and direct input channels can be used independently.The sample and hold inputs samples all channels simultaneously and thus reduces the skew introduced by scanning. The amount of skew removed depends on the cutoff frequency setting of the lowpass Filter (see next paragraph). When reducing the filter bandwidth, the propagation delay increases between the channels which causes a larger delay betweenchannels programmed to the same bandwidth (see specifications for delay values). The circuitry provides a voltage gain of .5, 8, 64, or 512 for each channel.The SCP also has a lowpass Filter on each sample and hold channel. The filter is a 6th order Bessel Active RC filter used to provide alias protection and noise reduction. The filter cutoff frequencies are 1kHz, 500Hz,250Hz, 100Hz, and 15Hz.If measuring transducers, like strain gages, that may have an initial offset voltage, the SCP uses an autobalancing circuit that can null out the offset voltage.Figure 1 shows a simplified block diagram of the SCP. The figure shows both the sample and hold and direct inputs.HP E1510Sample andHold Input SCPAmplifierFilter HLTo HP E1413Input +-Sample/Hold CircuitHL HL Terminal Module S/H Input Direct Input INPut:GAIN INPut:FILTer[:LPASs]:FREQuencyGHLG Figure 1 HP E1510, Simplified Block DiagramConnecting To The Terminal ModuleThis section shows how to make connections to the Terminal Module.The SCP connections for the Terminal Modules are shown on the stick-onlabels that came with the SCP.

The commands listed in this sectionare below and also in Chapter 5 of the HP E1413 User’s Manual.SCPI CommandsUsedThe following table lists all commands used in this section of the manual.Command DescriptionCALibration:SETup calibrates all of the SCPsCALibration:SETup?returns a value when CALibration:SETup is done CALibration:TARE (@<ch_list>)calibrates SCP and external offsets on thespecified channelsCALibration:TARE?returns a value when CALibration:TARE is done DIAGnostic:OTDetect <enable>,(@<ch_list>)enables or disables Open Transducer Detection INPut:FILTer[:LPASs]:FREQuency <cutoff_freq>,(@<ch_list>)selects the low pass filter cufoff frequency INPut:GAIN <chan_gain>,(@<ch_list>)selects the sample and hold gainSYSTem:CTYPe? (@<channel>)returns the SCP typeChecking the ID ofthe SCP Use the “SYSTem:CTYPe? (@<channel>)” command to verify the SCP type(s) in the HP E1413.•The channel parameter specifies a single channel in the channelrange covered by the SCP of interest. The first channel numbersfor each of the eight SCP positions are: 0, 8, 16, 24, 32, 40, 48, and 56.The value returned for the SCP in an HP E1413B is:HE WLE TT-PACKARD, E1413 Opt 20 4-Ch Sample and Hold Input SCP,0,0The value returned for the SCP in an HP E1313A/E1413C is:HE WLE TT-PACKARD, E1510 4-Ch Sample and Hold Input SCP,0,0To determine the type of SCP installed on channels 0 through 7, send: SYST:CTYP?

This command calibrates the A/D offset, and channel Gain/Offsetfor all 64 channels. This command is similar to the *CAL? command (seeChapter 5 of the “HP E1413 User’s Manual” for more information).Using the CALibration:TARe CommandIf using the SCP for measuring transducers, like strain gages, you can usethe CALibration:TARE (@<ch_list>) command to null out small offsetvoltages produces by the transducers. The command also enables the*CAL? command and thus calibrates the A/D offset, and channelGain/Offset for all 64 channels. When using the CALibration:TAREcommand, use the CALibration:TARE? command to determine whencalibration is complete. For example:CAL:TARE (@100:107)calibrate SCP and offset voltage(on channels 100 to 107)CAL:TARE?to return the success flag from theCAL:TARE operationSetting the Filter Cutoff Frequency To set the sample and hold channel cutoff frequency, use theINPut:FILTer[:LPASs]:FREQuency <cutoff>,(@<ch_list>) command.•The cutoff parameter can specify 15Hz, 100Hz, 250Hz, 500Hz,1000Hz, MIN, or MAX. MIN specifies 15Hz and MAX specifies 1000Hz.To set channels 0 through 3 to the 100Hz cutoff frequency, send:INP:FILT:FREQ 100,(@100:103)send cutoff frequency commandNotes The *RST and Power-On condition for the cutoff frequency is MIN (15Hz) for all sample and hold channels.The cutoff frequency is only applicable for sample and hold channels(lowest four channels) and not the direct input channels (highest fourchannels).Querying the Filter Cutoff Frequency To query any sample and hold channel for its cutoff frequency, use the INPut:FILTer[:LPASs]:FREQuency? (@<channel>) command. The INP:FILT:FREQ? command returns the cutoff value currently set for the specified channel.•The channel parameter must specify a single channel.To query the cutoff frequency for channel 3 send:INP:FILT:FREQ? (@103)query channel 3enter statement here returns 15, 100, 250, 500, or 1000Setting the Amplifier Gain To set the channel gain for the sample and hold channels, use the INPut:GAIN <gain>,(@<ch_list>) command.•The gain parameter can specify 0.5, 8, 64, 512, MIN, or MAX.MIN specifies 0.5 and MAX specifies 512.•Since the SCP can only output a maximum of ±5V, use the 4Vrange (A/D gain of 4) of the HP E1413 for most measurements. To set sample and hold channels 0 through 3 to a gain of 8, send: INP:GAIN 8,(@100:103)send gain commandNotes The *RST and Power-On condition for the amplifier gain is MIN (0.5) for all sample and hold channels.The amplifier gain is only applicable for sample and hold channels (lowestfour channels) and not the direct input channels (highest four channels).Querying the Amplifier Gain To query the sample and hold channels to determine the gain setting, use INPut:GAIN? (@<channel>) command. The INP:GAIN? command returns the current gain value of the specified channel.•The channel parameter must specify a single channel.To query the gain of channel 2, send:INP:GAIN? (@102)query channel 2enter statement here returns 0.5, 8, 64, or 512Detecting Open Transducers The SCP provides a method to detect open transducers on all channels of the SCP. When Open Transducer Detect (OTD) is enable, the SCP injects a small current into the HIGH (H) and LOW (L) input of each applicable channel. The polarity of the current pulls the HIGH inputs toward +17V and the LOW inputs toward -17V. If a transducer is open, measuring that channel returns an over-voltage reading. OTD is available on a per SCP basis. Thus, all eight channels are enabled or disabled together. See Figure 8 for a simplified schematic diagram of the OTD circuit.Note 1.) When OTD is enabled, the inputs have up to 0.2µA injected into them.If this current will adversely affect your measurements, but you still wantto check for open transducers, you can do the following:enable OTDwait for a while (about 2 seconds; see note 2)make a single scancheck CVT for over-voltage readingsdisable OTD and make your regular measurement scansThe specifications only apply when OTD is off.2.) When using Open Transducer Detect, allow a 2 seconds for the inputfilter on the SCP to charge.To enable or disable Open Transducer Detection, use theDIAGnostic:OTDetect <enable>,(@,<ch_list>) command.•The enable parameter can specify ON or OFF (OFF is defaultvalue).•An SCP is addressed when the ch_list parameter specifies a channelnumber contained on the SCP. The first channel on each SCP is:0, 8, 16, 24, 32, 40, 48, and 56To enable Open Transducer detection on all channels on SCPs 1 and 3,send:DIAG:OTD ON,(@100,116)0 is on SCP 1 and 16 is on SCP 3To disable Open Transducer Detection on all channels on SCPs 1 and 3,send:DIAG:OTD OFF,(@100,116)Measuring StrainGagesThe following example shows how to make a sample and hold strain measurements. The example uses channels 100:103 (sample and holdinputs) for the sample and hold measurement and channels 104:107 (direct inputs) to measure the external excitation voltage (see Figure ). The example assumes a full bending poisson strain measurements.Bridge is UnstrainedThe following commands calibrates the module, reads and stores the external excitation voltage, and reads the bridge output voltage. Do this when the bridge is in the Unstrained configuration. The commands are separated into three parts. The first part calibrates the SCP. The second part reads and stores the excitation voltage.

2、打开NEXIA软件图标，进入软件。
点击TOOL——Options，如下图红圈处连接NEXIA主机的网络设置进入Network进行如下设置。
3、开始连接主机，并进行对主机信息的设置。
如图点击按钮。
若连接成功。
则出现如下系统连接界面。
如图点击选项更改主机IP更改主机名称擦除数据4、写入程序。
打开准备写入的程序。
点击如同所示，点选所要写入主机的Serial#号。
选好后，我们开始写入程序，如图：第二篇：NEXIA的级联教程我们这里以两台NEXIA主机的级联作为讲解。
首先，我们使用的都是新拿出来的主机，因此两台主机的默认的IP地址均为192.168.1.101，为了能同时连接上两台主机，我们需要更改其中一台主机的IP 地址，考虑到方便管理，另一台主机预设为192.168.1.102，具体方法参见：更改主机IP。
更改好IP之后，我们就开始级联，这里我们需要一台交换机，用普通网线将两台主机的Ethernet接口及电脑的网口接入到交换机上，同时用普通的网线按图连起，如图。
下面我们将设置连接主机的网络设置。
同上面的连接主机的网络设置，注意，由于系统中有两台主机，因此要将两台主机的Node号选择上，如图做好这些之后，我们开始连接主机，点击。
