Testing the Current Function
To verify the accuracy of AC current measurement functions, do the following:
1. Using jaw of the meter around the suitable wire or conductor.
3. Apply the inputs for steps 1-2 in Table 3.
4. For each input, compare the readings on the Meter display to the reading in Table 3.
5. If the display reading falls outside of the range shown in the Table 3, the meter does not meet
specification.

Testing the uA Function
To verify the accuracy of the uA function, do the following:
1. Connect the calibrator to
V
Ω
and
COM
on the Meter.
3. Apply the inputs for step 1-2 in Table 4.
4. Compare the Meter display readings to the display readings in Table 4.
5. If the display reading falls outside of the range shown in Table 4, the Meter does not meet
specification.

Testing the Capacitance Function
The Meter measures capacitance by charging the capacitor with a known Direct current,
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
V
Ω
Hz
and
COM
inputs on the Meter. For steps 1-4 in Table 5.
2. Turn the rotary switch to .
3. Compare the reading on the Meter display to the reading in Table 5.
4. If the display reading falls outside of the range shown in Table 5, the Meter does not meet
specification.
