6. Compare the reading on the Meter display to the display reading for step 1 in
Table 8.
If the display reading falls outside of the range shown in Table 8, the Meter does not
meet specification.
7. Press Mto begin displaying minimum values.
8. Compare the reading on the Meter display to the display reading for step 2 in
Table 8.

Testing the mV DC Function
To test the accuracy of the mV dc function, do the following:
1. Connect the Calibrator to the
z and COM inputs on the Meter.
2. Turn the rotary switch to
mL .
3. Apply 350.0 mV.
4. Compare the reading on the Meter display to the display reading for your Model
shown below.
Model 83 III 348.8 to 351.2
Model 85 III 349.5 to 350.5
Model 87 III 349.5 to 350.5
If the display reading falls outside of the range shown, the Meter does not meet
specification.
Testing the Resistance Function
To verify the accuracy of the resistance function, do the following:
1. Connect the Calibrator to
z and COM on the Meter.
2. Turn the rotary switch to
Ω.
3. Apply the inputs for steps 1-5 in Table 9.
Compare the Meter display readings to the display readings for your Model of
Meter.
4. Press Kon the Meter to enter the 40-nanosiemen range used for conductance
tests of high resistances. Then proceed with step 6 of Table 9.
