Keithley 2000 Calibration Manual

DC current calibration
After the 1M Ω resistance point has been calibrated, the unit will prompt you for 10mA. Fol-
low these steps for DC current calibration:
1. Connect the calibrator to the AMPS and INPUT LO terminals of the Model 2000 as
shown in Figure 2-3.
2. Calibrate each current step summarized in Table 2-5. For each step:
• Set the calibrator to the indicated DC current, and make sure the unit is in operate.
• Make sure the Model 2000 display indicates the correct calibration current.
• Press ENTER to complete each step.
• Allow the Model 2000 to finish each step.
NOTE If you are performing DC-only calibrator, proceed to the “Setting calibration dates”
paragraph.
