4-58. Testing the Meter
You can use the error mode feature of the calibrator to test the meter. To verify that all
ranges of all functions are within specifications, proceed as follows:
1.
Turn on the calibrator and allow it to warm up.
2.
Execute dc zeros calibration. Do this by pressing the following sequence of softkeys:
“Setup Menus” → “Cal” → “Zero”
3.
Press P twice to get out of the calibration menu.
4.
Verify that the EX GRD and EX SNS indicators are off; if either is lit, press X and
x as necessary.
5.
Test the dc voltage function as follows:
a.
Verify that the calibrator is in standby and connect the meter as shown in
Figure 4-11.
b.
Turn on the meter and set its function switch to dcV.
c.
Set the warmed up calibrator to 2.7V dc. Press O.
d.
Use the output adjustment controls to adjust the calibrator’s output for a reading
of +2.70 on the meter.
e.
Verify that the error shown on the control display is less than the specification
for the meter (see the service manual for the specifications).

f. Check the meter error at 27V and 270V. Hint: use Y. See if the errors are
within specification. When
Y causes the output to go over 22V, the calibrator
goes into standby. When this happens, press
O to operate.
