2-10 Calibration
DC current calibration
After the 1MΩ resistance point has been calibrated, the unit will prompt you to apply 10mA.
Follow these steps for DC current calibration:
1. Connect the calibrator to the AMPS and INPUT LO terminals of the Model 2700 as
shown in Figure 2-3.

Connections for DC and AC amps calibration
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 2700 display indicates the correct calibration current.
• Press ENTER to complete each step.
• Allow the Model 2700 to finish each step.
NOTE If you are performing DC-only calibration, proceed to “Setting calibration dates
and saving calibration.”
