Keithley 2010 Service Manual

NOTE If your calibrator cannot output the values recommended in Table 2-3, use the left and
right arrow keys, and the up and down range keys to set the Model 2010 display value
to match the calibrator output voltage.
Resistance calibration
Completing the 100V DC calibration step ends the DC voltage calibration procedure. The
Model 2010 will then prompt you to connect 10Ω. Follow these steps for resistance calibration:
1. Set the calibrator output for resistance, and turn on external sense.
NOTE Use external sense (4-wire
Ω ) when calibrating all resistance ranges. Be sure that the
calibrator external sense mode is turned on.
2. Perform the calibration steps summarized in Table 2-4. For each step:
• Set the calibrator to the indicated value, and place the unit in operate. (If the calibrator
cannot output the exact resistance value, use the Model 2010 left and right arrow keys
and the range keys to adjust the Model 2010 display to agree with the calibrator
resistance.)
• Press the ENTER key to calibrate each point.
• Wait for the Model 2010 to complete each step before continuing.
