12.5 Procedures (CH1): DC mV/Volts (Source)
Do the procedure as follows:
1. Connect the applicable calibration equipment. Refer to Table
1.
2. Let the equipment get to a stable temperature (minimum: 5
minutes since the last power on).
3. Use the calibration menu (see Section
12.1) to do a two-point volts or mV source calibration
(Zero and +FS) for the applicable range:
a. mV (source) ranges:
•
2000
mV
b. Volts (source) ranges:
•
20
V

V)
4. Check the calibration is correct:
a. Select the applicable Millivolts or Voltage (measure) function via the Calibrator Task
Menu.
b. Apply the input values that are applicable to the calibration:
mV: 0, 100, 200, 1000, 2000
Volts (V): 0, 5, 10, 15, 20
