HiLOGGER数据记录器LR8400-20系列产品介绍说明书

Data Loggers-20-20-20Portable Data Logger with 30 Standard ChannelsExpandible to 60 ChannelsOnly the size of an A4 sheet of paper, the HIOKI LR8400-20 Series is the real-ization of our goal to build a logger that provides the existing functionality of a multi-channel data logger in a portable format. The new model comes with 30 channel capability as standard, to which another 30 channels can be added. All input channels for measuring temperature (with thermocouples), or voltage are isolated for safety, culminating in a powerful multi-measurement system that also offers pulse and logic inputs. Long-term logging is coupled with the capability to protect data against unexpected power outages and other problems for stable re-cordings over an entire year (see note).Note: Continuous recordings lasting longer than 1 year are also possible.2In fuel cell, electric automobile and other development ■ High withstand voltage■ High-speed sampling■ Multi-channel measurementsIn the development of fuel cells, multiple power-generating cells ■ Environmental measurements to prevent global warming ■ Development of fuel cell materials, energy field■ Development of automobiles, testing of automobile parts ■ Maintenance and inspection of equipment■ Monitoring plants■ Testing of electrical products ■ Impedance testing of electronic parts■ Maximum rated voltage to earth: 300 V AC/DC■ Maximum voltage that can be input between terminals: ±100 V DC■ Maximum rated voltage between each channels of VOLTAGE/TEMP UNIT: 250 V DC■ Maximum rated voltage between each channels of UNIVERSAL UNIT: 300 V DC Providesassistance with3Measure and record:■ Temperature & humidity■ A variety of transducer outputs (DC voltage) ■ Resistance valuesAlso comes with high withstand voltage; isolated inputs required when measuring and recording battery cell voltages• Temperature measurements of thermocouples on 30 channels• M3 screw terminal inputs enable secure connection of even thin thermocouples• Special sensor permits humidity measurements on 30 channels (optional Z2000)Note: The sensor power supply is the M3 mm dia. screw terminal block on the left side.Note: Both universal input terminals and M3 mm dia. input terminals enable humidity measurements.• 30 input channelsNote: The LR8400-20, LR8401-20 and LR8402-20 models differ in the combination of input functions and terminals.• All input channels are isolatedNote: Maximum rated voltage above ground between the HiLOGGER and analog inputs is 300 V AC/DC.Note: Maximum channel-to-channel voltage is a high voltage of 300 V DC. (Maximum voltage formodels with M3 screw input terminals is 250 V DC.)• 8 channel inputs (pulse and digital input selectable for each channel)• For measuring energy consumption and cumulative flow• The input signal shares commonground with the HiLOGGERNote: M3 screw input terminals provide direct connection• 8 channel inputs (pulse and digital input selectable for each channel)• For measuring rotational irregularities of motors and drills• The input signal shares commonground with the HiLOGGERNote: M3 screw input terminals provide simple connection• 8 channel inputs (digital and pulse input selectable for each channel)• 1 or 0 is recorded for each recording interval• The input signal shares commonground with the HiLOGGERNote: M3 screw input terminals provide simple connectionLogical 1-0 measurementPulse rotations measurementHighlightsMulti-measurements• Universal inputs support temperature measurements using Platinum resistance temperature sensor (Pt100/ JPt100), or resistance measurements (four wires)Note: These cannot be measured using the M3 screw input terminals units.Note: Supports resistance recording to enable assessment ofchanges in resistance in the device under test. 4-terminal method, measurement resolution 0.5 mΩ -, testing current 1 mA■ A compact A4 size enhances mobilityA compact A4 size footprint makes it ideal for use in virtually any environment.■ Helps also in collecting automotive data Ideal for testing and collecting data on the vibration characteristics of automotive partsive dataotive da the on the To record 4 - 20mA instrumentation signals, attach a commercially available 250Ω shunt resistanceto the input terminals (between + and -) to convert the signals to 1 - 5 V. Then use the 1-5V or the 10V f.s. input range in the HiLOGGER.4■ Enhanced noise suppressionA digital oversampling fi lter function reduces inverter switching noise and 50/60 Hz hum noise, a concern in earlier models, during recording.Note: The noise reduction effect improves with longerrecording intervals (i.e., at slower sampling speeds).Sampling at 100 ms intervals cannot capture abrupt load changes■ 10 ms high-speed samplingThe development of hybrid and electric automobiles requires instruments that can measure abrupt load changes. Channels 1 to 15 provide 10-ms sampling and channels 16 to 30 provide 20-ms sampling. This channels allow you to track waveforms not possible with earlier models.Note: Measurements on channels 31 to 60 provide 50-ms sampling.Accurately capture any phenomena you want to measureSampling the same waveform at ten times the speed, at 10 ms intervals,accurately captures the changes.Without electric noise reduction, you will obtain a waveform like the one above in temperature measurements of an electromagnetic cookerA digital fi lter in the HiLOGGER eliminates high-frequency noise to enable accuratetemperature waveforms■ 5.7 inch TFT LCD display is easy to view even at an angleThe LCD has a wider visual angle and is larger (5.7 inches, 640 × 480 dots)than the STN LCD in our previous model (8420-51s) to facilitate observation of waveforms on multiplechannels.HighlightsHigh-speedRecordingHighlightsNoisesuppressionHighlightsEasy-to-view LCD5■ Compatible with USB memory devicesFor even greater convenience, the HiLOGGER now provides support for USB memory devices. Measurements can now immediately be written to a USB memory device in real-time. USB memory devices are also a handy means to transfer data to a PC.Note: Although USB memory devices enable real-time saving of data, for more reliable data protection we recommend use of HIOKI CF cards, which are guaranteed to work with the instrument, for real-time saving of data.■ Cards can be replaced during real-time recordingThis function has been provided to enable removal of cards during recording to allow the user to analyze the data recorded so far.This makes it possible to replace USB memory devices and CF cards during real-time recording without having to stop measurements.Note: During high-speed recording, be sure to insert the new storage media within 2 minutes ofremoving a card.Recording intervalsRecording of 15 analog channels only (no pulse measurement, alarm output or waveform processing data)Internal memory (16 MB)Model 9727(256 MB)Model 9728(512 MB)Model 9729(1 GB)Model 9830(2 GB)10 ms ** For 15 or fewer analog channels1h 33m 1d 00h 51m2d 01h 42m4d 03h 25m8d 06h 50mRecording intervalsRecording of 30 analog channels only (no pulse measurement, alarm output or waveform processing data)Internal memory (16 MB)Model 9727(256 MB)Model 9728(512 MB)Model 9729(1 GB)Model 9830(2 GB)20 ms ** For 30 or fewer analog channels1h 33m 1d 00h 51m 2d 01h 42m 4d 03h 25m 8d 06h 50m 50ms 3h 53m 2d 14h 08m 5d 04h 16m 10d 08h 33m 20d 17h 06m 100ms 7h 46m 5d 04h 16m 10d 08h 33m 20d 17h 06m 41d 10h 12m 200ms 15h 32m 10d 08h 33m 20d 17h 06m41d 10h 12m82d 20h 24m500ms 1d 14h 50m 25d 21h 22m51d 18h 45m 103d 13h 30m 207d 03h 01m1s 3d 05h 40m51d 18h 45m 103d 13h 30m 207d 03h 01m 414d 06h 03m2s 6d 11h 20m 103d 13h 30m 207d 03h 01m 414d 06h 03m "★"5s 16d 04h 21m 258d 21h 47m 517d 19h 34m "★""★"10s 32d 08h 43m 517d 19h 34m"★""★""★"20s 64d 17h 26m "★""★""★""★"30s 97d 02h 10m "★""★""★""★"1min 194d 04h 20m "★""★""★""★"2min388d 08h 40m"★""★""★""★"5min to 1hour"★""★""★""★""★"• Maximum recording time is inversely proportional to number of recording channels.• Because the actual capacity of a CF card is less than that indicated, and because the header portion of waveform files is not included in capacity calculations, expect actual maximum times to be about 90% of those in the table.• "★" exceeds 1 year.Note: Use only HIOKI CF cards that are guaranteed to operate with the HiLOGGER for continuous long-term recording.Store data securely for more than 1 year■ Saving data to CompactFlash (CF) cardUse only HIOKI CF cards, which are manufactured to strict industrial standards, for long-term storage of important data.Note: Operation of non-HIOKI CF cards is not guaranteed■ Recording CapacityHighlightsStorage MediaHighlightsReplacing cards6■ Up to two additional 15 channel input units can be addedThe need for more measurement channels can be met even after purchasing the instrument. Theinstrument comes with 30 channels as standard, but another two 15 channel input units can be added to expand the total number of channels to 60.Note: The units provided with the unit as standard cannot be removed.A host of useful functions and features■ Input setting screens with waveform monitoringThe HiLOGGER adopts the setting screens that earned its sister model (8430-20) a reputation for user-friendliness. Range settings, warnings, triggers, waveform processing and other measurement input settings can be taken in at aglance.VOLTAGE/TEMP UNIT LR8500● 15ch● M3 screw terminals(2 terminals per channel)UNIVERSAL UNIT LR8501● 15ch● Push-button type terminals(4 terminals per channel)Function highlightsEasyinstallationFunction highlightsEase of use7LAN■ USB and LAN connection for easy setupThe supplied Logger Utility software allows you to set up the logger from a PC. Setup could not be easier. Just follow the numbered procedures to set up the instrument.Note: Data on an inserted CF card can be copied to a PC via USBconnection.Note: The Logger Utility will enable LAN access with software Ver. 1.20or later.■ Simultaneous recording to storage media and PCMeasurement data can be simultaneously saved to external storage media and a hard disk on a PC connected to a network to reduce the risk data loss.USB■ Real-time processing functionsThe HiLOGGER comes with [four arithmetic operation] functions for processing between channels. Data processed in real-time can be displayed in graph form. In addition, processing results for 30 channels are stored in internal memory and can be handled as data for independent input channels.Trickle charging the internal batteryAn internal battery (optional accessory) is charged when the AC adapter is connected. Since the internal battery will automatically take over in the event of a sudden power outage, it permits uninterruptible operation.■ Protection of files being stored on external storage mediaAn internal high-capacity capacitor will provide enough power to store any data at risk on a CF card or USBmemory device should a sudden power outage occur during long-term storage. This reduces the risk of data loss and corruption of the fi le system. Measurements will resume as soon as the power returns.■ Alarm outputThe HiLOGGER outputs a signal when alarm criteria are satisfi ed and also sounds a buzzer. Four systems are provided as standard and separate criteria can be set for each input source enabling OR and AND criteria between channels.Note: Open-collector output (5 V voltage output and relay drive capacity 5 to 30 V, 200 mA)■ Records average values every 30 minutesThe HiLOGGER contains a [time-span processing]function. The instrument will save processing data as text data for a preset time period in real-time.Function highlightsAlarm output■ An is cconwilof aFunction highlightsWeathers power outagesFunction highlightsCalculation FunctionsFunction highlightsUSB / LAN Communication8■ Analyze after measuringOur new “dual-knob function” greatly simplifi es data analysis.

devices do not have to be directly aligned,however there should be a clear line-of-sight between the two.The RS232cable will work as normal,regardless of whether the IR circuitry is on or not.However,attempting to use both the cable and the InfraRed simultaneously will result in communication errors.The OM-EL-2-IR is designed to communicate with devices which have IrDA-compatible InfraRed ports.If your computer doesn't have one of these,OMEGA’s OM-EL-LINK-IR can be used to convert a normal serial port.Simply plug the OM-EL-LINK-IR into the 9-way serial port and point it in the right direction.If you use a serial extension cable,ensure that it is a straight-through.Null modem and EasyLog cables will not work.Pressing the button to turn on the IR circuitry will not affect the logger itself,e.g.if it's in push to start,or push to log mode.Conversely,a short press,say for a push to log,will not affect the IR circuitry.The duration that the button is held down for determines what the press is intended for.Step 1:Step 2:Step 3:Simply hold down the button for 2-3seconds.The Actiwave symbol will flash once.Place the logger in line of sight of the IR port on your PC.That's it!T o maximise battery life,after no communications activity has occurred for about five minutes,the IR circuitry will automatically shut down.If the button is held down until the Actiwave flashes,the timeout period will be reset.USING EXTERNAL SIGNALSPIN FUNCTION A1,A2,REF .Output for test diagnostics.Do not use.HA.High Alarm output =V+when alarmed.SW .'Push to record
