AC Voltage Gain Calibration Procedure
Review the ““Test Considerations” on page 63 and “Gain Adjustment
Considerations” on page 82 sections before beginning this procedure.
Configuration: AC Voltage
1 Configure each function and range shown in the adjustment table
below.
2 Apply the input signal shown in the “Input” column of the table.
3 Enter the actual applied rms input voltage
(see “Entering Adjustment Values” on page 78).
a Successful completion of each adjustment value is indicated by the
message CAL SUCCEEDED flashing in the display.
b If a problem is encountered, the display will flash the message
CAL FAILED. Check the input value, range, function, and entered
adjustment value to correct the problem and repeat the adjustment
step.
4 Repeat steps 1 through 3 for each gain adjustment point shown in the
table.
5 Store the new calibration constants (“Storing the Calibration Constants” on
page 78.
