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
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
4.For each input, compare the readings on the Meter display to the display readings in Table 8.
