Testing the Resistance Function
To verify the accuracy of the resistance function, do the following:
1. Connect the Calibrator to VΩ and COM on the Meter.
2. Turn the rotary switch to Ω
3. Apply the inputs for step 1-7 in Table 5.
*Set reference if using a Multifunction Calibrator with diff or zero mode for steps 1, 2, and 3.
Compare the Meter display readings to the display readings in Table 5 step 1-7.
4. If the display reading falls outside of the range shown in Table 5, the meter does not
meet specification.

5. Press the blue button on the meter to toggle to LVΩ function.
6. Apply the inputs for step 1-6 in Table 6.
*Set reference if using a Multifunction Calibrator with diff or zero mode for steps 1 & 2.
Compare the Meter display readings to the display readings in Table 6.
7. If the display reading falls outside of the reading shown in Table 6, the meter does not
meet specification.

Testing the Capacitance Function
The Meter measures capacitance by charging the capacitor with a known direct current, and measuring the
resultant voltage, and calculating the capacitance. If the same capacitance is measured on an impedance bridge, a
different reading may result. This variance is likely to be greater at higher frequencies.
To verify the accuracy of the capacitance measuring function, do the following:
1. Apply the Capacitor to the VΩ and COM inputs on the Meter.
2. For steps 1 through 8 in Table 7.
a) Turn the rotary switch
b) Set the VΩ and COM inputs un-connected
c) Select Δ or (REL) for steps 1 and 2 in Table 7. After steps 1 and 2 are complete, escape
from Δ mode and press (RANGE) key until (AUTO) is displayed.
