Testing the Capacitance Function (cont’d)
d) For each input, compare the readings on the Meter display to display readings in
Table 7. The meter selects the proper range automatically. Each measurement takes
about one second per range. 5mF will taken about 15 seconds.
3. If the display reading falls outside of the range shown in Table 7, the Meter does not
meet specification.

Checking the Diode Test Function
To check the diode test function, do the following:
1. Connect the Calibrator to the VΩ and COM inputs on the Meter.
2. Turn the rotary switch to
.
3. Apply 3.000V.
The meter display should read approx. 3.000V dc.
4. Press “Blue” key to test
function.
5. Apply a 50Ω resistor to meter, the built-in beeper alarms.
Testing the Milliamp (mA) Function
To verify the accuracy of DC and AC current measurement functions, do
The following:
1. Connect the Calibrator to the mA and COM inputs on the Meter.
2. Turn the rotary switch to mA.
3. Apply the inputs for steps 1-2 in Table 8.
4. For each input, compare the readings on the Meter display to the display readings in
Table 8.

Input Readings
Step Current 61-633 61-635
1 36.000rnA 35.780 to 36.220 35.888 to 36.112
2 360.00mA 357.80 to 362.20 358.88 to 361.12
5. Press the blue button on the Meter to toggle to AC measurement function.
6. Apply the inputs for steps 1-4 in Table 9.
7. For each input, compare the readings on the Meter display to the display readings in
Table 9.
8. If the display reading falls outside of the range shown in the Tables, the meter does not
meet specification.
