7. Press f until AP is displayed in the top status line of the Tester.
8. Set the output of calibrator "A" to the Calibrator Output values in Table 4-3. DC
voltages are listed in the upper section of the table and AC voltages at 50 or 60 Hz,
whichever is your local line frequency, are listed in the lower section of the table.
Blank fields do not need to be evaluated.
Note
Apply the voltage incrementally, so the Tester does not autorange to the
next higher range. Ensure the Tester is in the appropriate range before
checking the reading against the performance limits.
9. Verify the readings are within the minimum and maximum limits specified in
Table 4-3.
Note
It is normal for the tester to display “**OL*%THD*” with a VDC input.
