2-14 Calibration
Table 2-4
Front panel current calibration
Source range
1. Use EDIT and RANGE keys to select source range.
2. Multimeter reading used in corresponding calibration step. See procedure.
3. Current calculated as follows: I = V/R, where V is the DMM reading, and R is the
characterized value of the 1Ω resistor. 10A pulse range calibrated simultaneously.
Step 4: Enter calibration dates and save calibration
