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 and COM inputs on the meter.

2.Turn the rotary switch to

a. 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.

Testing the DC milli amperes Function (for 61-340 and 61-342)

1.Connect the calibrator to the and COM inputs on the meter.

2.Turn the rotary switch to .

a. Press the SEL button to select the DC function

3.Apply the inputs for steps 1-4 in Table 3b.

4.For each input, compare the reading on the meter display to the reading for your meter in Table 3b

5.If the display reading falls outside of the range shown in Table 3b, the meter does not meet specification.
