DC current calibration

After the 1MΩ resistance point has been calibrated, follow these steps for DC current
calibration:
1.
2.

* Change parameter if using different current.
Connect the calibrator to the AMPS and INPUT LO terminals of the Model 2015 as
shown in Figure 2-3.
Perform the calibration steps listed in Table 2-11. For each step:
• Set the calibrator to the indicated current, and make sure the unit is in operate. (Use
the recommended current if possible.)
• Send the indicated programming command. (Change the current parameter if you
are using a different calibration current.)
• Wait until the Model 2015 completes each step before continuing.
If you are performing DC-only calibration, proceed to Programming calibration
dates.
