Keithley 2701 Service Manual

1-26 Performance Verification Model 2701 Service Manual
2. Install the Model 7700 in Slot 1 of the Model 2701, then turn on the power and allow
the unit to warm up for two hours before proceeding. Be sure the front panel INPUTS
switch is set to the REAR position.
3. Set the calibrator for 4-wire resistance with external sense on.
4. Select the Model 2701 4-wire resistance function by pressing the Ω4 key. Close
Channel 1 by pressing the CLOSE key and keying in 101.
5. Set the Model 2701 for the 100Ω range and make sure the FILTER is on. Enable
OCOMP (offset-compensated ohms) for the 100Ω range test. (Press SHIFT then
OCOMP.)
6. Recalculate reading limits based on actual calibrator resistance values.
7. Source the nominal full-scale resistance values for the 100Ω-10MΩ ranges summarized
in Table 1-13 and verify that the readings are within calculated limits.
