4. Test the ac voltage function:
a.
Press R on the calibrator and set the DMM function switch to K.
b.
Set the output of the calibrator to 350 mV at 60 Hz. and press O. Verify the
errors are within specifications.
c.
Check the error against specifications at the following voltages and frequencies:
Voltage
Frequency
350 mV
60 Hz, 5 kHz, & 20 kHz
3.500 V
60 Hz, 5 kHz, & 20 kHz
35.00 V
60 Hz, 5 kHz, & 20 kHz
329.0 V
60 Hz, 5 kHz, & 20 kHz
100.0 V
20 kHz
200.0 V
20 kHz
300.0 V
20 kHz
1000 V
60 Hz & 5 kHz
5. Test the Frequency function:
a. Press Ron the calibrator, set the DMM function switch to p, and press Hz
on the DMM.
b. Set the calibrator to 150 mV at 19.0 kHz and press O. Verify the error is
within specification.
c. Set the calibrator to 150 mV at 190 kHz. Hint: press e twice to move the
cursor to the frequency reading in the output display and press X. Verify the
error is within specification.
6. Test Frequency Sensitivity and Trigger Levels:
a. Press R on the calibrator, set the DMM function switch to pand press Hz on
the DMM to choose the frequency mode.
b. Set the calibrator to 300 mV at 1 kHz and press O. Verify the frequency error
is within specification.
c. Change the calibrator output to 1.7 V. Verify the frequency error is within
specification.
d. Change the calibrator output to 1.0 V. Verify that the DMM displays 000.0
frequency.
e. Change the DMM range to 40 V by pressing RANGE. Change the calibrator
output to 6.0 V. Verify the frequency error is within specification.
f.
Change the calibrator output to 2.0 V. Verify that the DMM displays 000.0
frequency.
