3. Test the dc voltage function as follows:
a. Turn on the DMM and set its function switch to .
b. Set the warmed up calibrator to 3.5 V dc. Press O.
c. Use the output adjustment controls to adjust the calibrator output for a reading of
+3.5000 on the DMM display.
d. Verify that the error shown on the control display is less than the specification for
the DMM in its Users Manual.
e. Check the DMM error at 35.0 V, -35.0 V, 350.0 V. Hint: use the X. Verify the
errors are within specification. When X causes the output to go over 33 V, the
calibrator goes into standby. When this happens, press O to operate.
f. Check the DMM error at 1000 V to verify it is within specification.
g. Set the output of the calibrator to 350 mV and press O. Verify the errors are
within specifications.
4. Test the ac voltage function:
a. Press R on the calibrator and set the DMM function switch to .
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
350 mV
3.500 V
35.00 V
329.0 V
100.0 V
200.0 V
300.0 V
1000 V
5. Test the Frequency function:
a. Press R on 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  and 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.
