Testing the DC microamperes Function (for 61-340 and 61-342)
To verify the accuracy of AC and DC current measurement functions, do the following:
1. Connect the calibrator to the
2. Turn the rotary switch to the
and COM inputs on the meter.
position. Press the SELECT button to select the DC function.
3. Apply the inputs for steps 1 - 3 in Table 3a.
4. For each input, compare the reading on the meter display to the reading for your meter in Table 3a.
5. If the display reading falls outside of the range shown in Table 3a, the meter does not meet
specification.
