Only properly trained service personnel may perform installation and service procedures.Keithley Instruments products are designed for use with electrical signals that are rated Measurement Category I and Measurement Category II, as described in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most measurement, control, and data I/O signals are Measurement Category I and must not be directly connected to mains voltage or to voltage sources with high transient over-voltages. Measurement Category II connections require protection for high transient over-voltages often associated with local AC mains connections. Assume all measurement, control, and data I/O connections are for connection to Category I sources unless otherwise marked or described in the user documentation.Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or test fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than 30V RMS, 42.4V peak, or 60VDC are present. A good safety practice is to expect that hazardous voltage is present in any unknown circuit before measuring.Operators of this product must be protected from electric shock at all times. The responsible body must ensure that operators are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential human contact. Product operators in these circumstances must be trained to protectThe WARNING heading in the user documentation explains dangers that might result in personal injury or death.

Do not perform these procedures unless you are qualified to do so.Failure to recognize and observe normal safety precautions could result inpersonal injury or death.This section includes information on making connections to the Model 2000-SCAN and on installing the card in a Model 2000/2001/2002 Multimeter. This section is arranged as follows: Handling precautions —Explains precautions that must be followed to preventcontamination to the scanner card assembly. Contamination could degrade the performance ofthe scanner card.Connections —Covers the basics for connecting external circuitry to the scanner card.Typical connection schemes —Provides some typical connection schemes for 2-pole and 4-pole operation.Card installation and removal —Summarizes the procedure to install the scanner card in a multimeter, outlines scanner card output connections, and describes how to remove the card.Handling precautionsTo maintain high impedance isolation between channels, care should be taken when handling the scanner card to avoid contamination from such foreign materials as body oils. Suchcontamination can substantially lower leakage resistances, degrading card performance. Toavoid possible contamination, always grasp the scanner card by the side edges or covers. Do nottouch board surfaces, components, or areas adjacent to electrical contacts.Dirt build-up over a period of time is another possible source of contamination. To avoid this problem, operate the multimeter and scanner card in a clean environment. If the card becomescontaminated, it should be thoroughly cleaned as explained in Section 4 “Handling and cleaningprecautions”.Card Connections and Installation2-3ConnectionsThis paragraph provides the information necessary to connect your external test circuitry to the scanner card.NOTE All connecting wires or leads must be connected to the card before it is installed in amultimeter.Connection precautionsWARNING Connection information for the Model 2000-SCAN is intended for qualifiedservice personnel. Do not attempt to connect the DUT or external circuitryto a scanner card unless qualified to do so.To prevent electric shock that could result in serious injury or death, adhereto the following safety precautions:•Before making or breaking connections to the scanner card, make surethe DMM power is turned off and power is removed from all externalcircuitry.•Do not connect signals that will exceed the maximum specifications of thescanner card.If both the front panel terminals and the scanner card terminals areconnected at the same time, the maximum signal ratings of the front panelterminals are reduced to the maximum signal ratings of the scanner card.As described in the International Electrotechnical Commission (IEC)Standard IEC 664, scanner cards are Installation Category I and must notbe connected to mains.Card configurationFigure 2-1 shows a simplified schematic diagram of the Model 2000-SCAN. The scanner card has ten input channels and two outputs. Channels 1-10 are all switched by relays.4-pole paired channels are as follows:•Channels 1 and 6•Channels 2 and 7•Channels 3 and 8•Channels 4 and 9•Channels 5 and 10Figure 2-1Model 2000-SCAN simplified schematic 2-4Card Connections and InstallationFigure 2-2 shows the input/output connectors for the card. Card connections include:•CH 1-10 (channels 1-10): HI and LO input terminals are provided for each of the 10 channels on the card. •OUT A: HI and LO output connections for all ten channels in the 2-pole mode or channels 1-5 in the 4-pole mode.•OUT B: HI and LO output connections for channels 6-10 in the 4-pole mode.In order to gain access to the connections, first open the plastic shield by pressing in on the locking tab. Swing the shield away from the circuit board.Figure 2-2Card connectors Card Connections and Installation 2-52-6Card Connections and InstallationWiring procedurePerform the following procedure to wire circuitry to the screw terminals on the scanner card.WARNING Make sure all power is off and any stored energy in external circuitry isdischarged before connecting or disconnecting wires.CAUTION Mechanical shock may open or close latching relays on the scanner card.Before enabling any external sources, open all relays by inserting theModel2000-SCAN into the multimeter and turning on the power.1.Open the plastic shield to gain access to the connectors.2.Strip approximately 5/16” of insulation from the end of each wire, then twist the strandstogether.NOTE#22 AWG stranded wire is recommended for scanner card connections.3.Loosen the screw terminal, then insert the wire into the access hole.4.While holding the wire in place, tighten the connector screw securely.5.Repeat steps 1 through 3 for each wire to be connected.6.Dress input wires through the cable clamp, as discussed in “Dressing leads” on page2-8.Output connectionsUse the supplied test leads for scanner output connections. Connect red leads to the output (OUT A and OUT B) HI terminals, and connect black leads to the output LO terminals. See Figure 2-3 for details. Dress output test leads through the cable clamp, as described in “Dressing leads” on page 2-8. After all wires are connected and secure, close the plastic shield, and secure it with the locking tab.NOTEIf you intend to use the scanner card only in the 2-pole mode, it is not necessary to connect output leads to both OUT A and OUT B. Use only OUT A for the 2-pole mode.After the scanner card is installed, the output leads must be connected to the multimeter rear panel input jacks. See “Output connections to multimeter” on page 2-17 for details.Figure 2-3Output connectionsDressing leadsAfter wires are connected to the terminal blocks, they should be dressed through the cable clamp as shown in Figure 2-4. To do so, unlatch the clip that holds the cable clamp together, then route all wires flat against the lower half of the clamp. Clamp the wires down, then secure the clamp with the metal clip unlatched earlier.Figure 2-4Routing wires through cable clampT ypical connecting schemesThe following paragraphs discuss typical connections for the scanner card.V oltage connectionsFigure 2-5 shows typical connections for voltage measurements. Note that all channels are used in the 2-pole mode, and that up to 10 voltage sources can be switched with thisconfiguration. This basic configuration can be used for the following types of measurements:•DCV •ACV•Frequency (voltage only)All channels (1-10) can be used with this configuration.Figure 2-5Connections for voltage scanningResistance connections2-Pole connectionsFigure 2-6 shows typical 2-pole resistor test connections. The 2-pole resistance configuration can be used to test up to ten DUTs.Figure 2-6Typical connections for 2-wire resistance scanning4-Pole connectionsTypical 4-pole resistance connections are shown in Figure 2-7. This general configuration can be used with all channels to scan:•4-wire resistance measurements.•4-wire RTD temperature measurements (Model 2001 and 2002 multimeters).Figure 2-7Typical connections for 4-wire resistance scanningCurrent measurementsCurrent shunts can be installed on the circuit board to allow indirect AC and DC current measurements to be made through channels 1 and 6 only. The following paragraphs discuss installing current shunts and the basic methods used to determine currents.CAUTIONBoard mounted current shunt resistors can be installed only for channels 1 and 6. A channel that has been modified with a current shunt resistor should not be used for voltage or resistance measurements.Current shunt locationsFigure 2-8 shows the locations for the user-installable current shunts. Location R145 is for channel 1 and R146 is for channel 6.Recommended current shunt valuesHole spacing on the circuit board is intended for 1/4W resistors. The resistance value will depend on the current you intend to measure; 1k¾ resistors should be optimum for many applications. A 1k¾ resistor will allow you to switch currents up to 15mA without exceeding the power rating of the resistor.For larger currents, decrease the shunt value. Conversely, the shunt value can be increased for smaller currents. CAUTIONDo not exceed the maximum card signal levels:•DC signals: 110V DC, 1A switched, 30 VA maximum.•AC signals: 125V AC rms or 175V AC peak, 1A switched, 62.5 VA maximum.Figure 2-8Current shunt locationsBoard cleaningNOTE Failure to observe the following precautions may result in degraded card performance.When soldering resistors, be sure not to touch areas not associated with resistor installation or spread flux around to other areas of the circuit board. Use solder with an OA (organic activated) flux. The circuit board should be thoroughly cleaned with pure water after soldering to remove all contaminants. After cleaning with water, swab the area with pure methanol, then allow the board to dry for several hours in a 50°C environment before use.Current measurementsEven with the current shunts installed, you cannot make direct current measurements with the scanner card. Instead, you must close the channel to be measured, and measure the voltage across the shunt. The current can then be calculated as follows:Where:I = current being determinedV= voltage measured by multimeterR= shunt resistance valueInstead of manually calculating current, set up a Model 2000/2001/2002 mX + b math calculation function. (Here, m = 1/R and b = 0.). The multimeter will then display the actual current value. Refer to the multimeter manuals for details on using math functions.Current connectionsFigure 2-9 shows typical connections for measuring currents using the Model 2000-SCAN with current shunts installed. As noted previously, only channels 1 and 6 have current shunts installed, and this configuration can be used to scan the following:•DC current •AC currentFigure 2-9Current connectionsCard installation and removalThis paragraph explains how to install and remove the Model 2000-SCAN card assembly from the Model 2000 Multimeter.WARNING Installation or removal of the Model 2000-SCAN should be performed onlyby qualified service personnel. Failure to recognize and observe standardsafety precautions could result in personal injury or death.NOTE To prevent contamination to the scanner card that could degrade performance,handle the card assembly only by the card edges and covers.Wiring connections must made before installing the scanner card. See “Typicalconnecting schemes” on page2-9 for wiring details.Scanner Card InstallationPerform the following steps and refer to Figure 2-10 to install the card assembly in the multimeter:WARNINGTurn off power to all instrumentation (including the multimeter) and disconnect all line cords. Make sure all power is removed and any stored energy in external circuitry is discharged.1.Remove the cover plate from the OPTION SLOT on the rear panel of the multimeter. To Do so, pry out the two fasteners, then remove the Cover plate.2.Slide the card edges into the guide rails inside the multimeter (solder side up for Model 2001/2002, component side up for Model 2000).3.With the ejector arms in the unlocked position, carefully push the card all the way forward until the arms engage the ejector clips. Push both arms inward to lock the card into the multimeter.4.After installation, connect the output leads to the multimeter as discussed below.Figure 2-10Card installation。
