Notice that these status register sets feed directly into the Status Byte Register. Voltage And Temperature Connections Test Circuit green CH 2 Ice Bath white Cable-to-thermocouple wire connection one of two Voltage and temperature connections Channel 1 should be used for voltage measurements since it supports a wider range of measurements, leaving Channel 2 to measure temperature.

Storing readings in buffer Comments to this Manuals Your Name. Aborting Calibration The calibration procedures described below are generally the only instrument calibration required in the field.

Turn on the computer, the Modeland the calibrator. Allow two minutes for thermal equilibrium.

Table of contents Safety Precautions General information Warranty information Warranty information is located at the front of this manual. This error indicates that one of the main 218a2 ROMs may require re-seating in its socket. Typical Command Sequences Page Example Pro- grams Example Programs Page Measurement Consider- ations Measurement Considerations Limits Setting limit values Use the following manuaal to enter high and low limit values: Page 68 Voltage and Temperature Measurements Subsequent measurements are performed on Channel 1.


Operation loops back to Device Action three more times to complete the scan cycle. Analog Signal Switching States Troubleshooting Analog signal switching states Table Table provide switching states of the various ICs and transistors 2182 the basic measurement functions and ranges.

Includes the effects of Filter on Delta measurements.

Delta measurements by the Model require the use of an alternating polarity source. Scpi Programming – Analog Output SAVE command is sent.

Table F-3 lists a typical bus sequence for sending the addressed multiline commands. These query commands are used to read the event registers. Once a device is addressed to talk or listen, the appropriate bus transactions take place.

By enabling Delta measurements on the Modelthe effects of thermal EMFs in the test leads will automatically be canceled during the source-measure process. If you are unsure about the applicability of a replacement component, call a Keithley Instruments office for information. Page 44 The thermocouple wires are connected to the copper lugs of the supplied input cable.

Figure Service Request Enable Register I use the A nanovoltmeter in conjunction with a current source, connected with a trigger link cable.

Temperature Measurement Accuracy Keiyhley, the following procedure is provided for those who wish to independently measure temperature measurement accuracy.


Page – Figure Setup of Model and Model The improved delta mode for the A current sources uses the same mxnual technique, but the way in which it’s implemented has been simplified dramatically. The test involves applying precise DC voltages and then verifying that the Model voltage readings are within required limits.

B Calibration Reference Precalibration commands: This procedure assumes that the case cover is already removed. Figure Line Fuse Replacement VMC required from the Model s is provided by unit 1. Figure Standard Event Status INITiate commands remove the Model from the idle state.

With continuous initiation enabled, operation continues at the top of the trigger model. During the warranty period, Keithley Instruments will, at its option, either repair or replace any product that proves to be defective. Example Send default code of KI All other trademarks and trade names are the property of their respective companies. When used with the immediate initiation command: Meter Loading – Percent error From the above equation, it is obvious that the input resistance of the Model must be at least times the value of source resistance if loading error is to be kept to within 0.

Performing the verification test procedures Be sure to short the Channel 1 input.
