c. Verify the error against specifications at the subsequent voltages and frequencies
in Table 4-3.
Table 4-3. Verification Voltages and Frequencies
Voltage Frequency
350 mV 60 Hz, 5 kHz, and 20 kHz
3.500 V 60 Hz, 5 kHz, and 20 kHz
35.00 V 60 Hz, 5 kHz, and 20 kHz
329.0 V 60 Hz, 5 kHz, and 20 kHz
100.0 V 20 kHz
200.0 V 20 kHz
300.0 V 20 kHz
1000 V 60 Hz and 5 kHz
5. Verify the frequency function:
a. Push on the Calibrator, set the DMM function switch to , and push Hz on
the DMM.
b. Set the Calibrator to 150 mV at 19.0 kHz and push . Make sure the error is
in specification limits.
c. Set the Calibrator to 150 mV at 190 kHz, push twice to move the cursor to
the frequency measurement in the output display and push . Make sure the
error is in specification limits.
6. Verify frequency sensitivity and trigger levels:
a. Push on the Calibrator.
b. Set the DMM function switch to and push Hz on the DMM to choose the
frequency mode.
c. Set the Calibrator to 300 mV at 1 kHz and push . Make sure the frequency
error is in specification.
d. Change the Calibrator output to 1.7 V. Make sure the frequency error is in
specification.
e. Change the Calibrator output to 1.0 V. Make sure that the DMM displays 000.0
frequency.
f. Push RANGE to change the DMM range to 40 V. Change the Calibrator output
to 6.0 V. Make sure the frequency error is in specification limits.
g. Change the Calibrator output to 2.0 V. Verify that the DMM shows 000.0
frequency.
