DC current calibration
After the 1MΩ resistance point has been calibrated, follow these steps for DC current
calibration:
1. Connect the calibrator to the AMPS and INPUT LO terminals of the Model 2010 as
shown in Figure 2-3.
2. Perform the calibration steps listed in Table 2-10. 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 2010 completes each step before continuing.
NOTE If you are performing DC-only calibration, proceed to Programming calibration
dates.
