Calibration 2-13
Table 2-4
Front panel current calibration
*Use EDIT and RANGE keys to select source range.
**Multimeter reading used in corresponding calibration step. See procedure.
***Current calculated as follows: I = V/R, where V is the DMM reading, and R is the
characterized value of the 1
Ω
resistor.
Step 4: Enter calibration dates and save calibration
NOTE
For temporary calibration without saving new calibration constants, proceed to
Step 5: Lock out calibration.
1.
From normal display, press MENU.
