Testing the DC microamperes Function (for 61-312 and 61-314)
To verify the accuracy of AC and DC current measurement functions, do the following:
1. Connect the calibrator to the V Ω Hz and COM inputs on the meter.
2. Turn the rotary switch to µA .
a. Press the SEL Button to select the DC function
3. Apply the inputs for steps 1 through 3 in Table 3a.
4. For each input, compare the reading on the meter display to the reading for your m
in Table 3a
eter
t 5. If the display reading falls outside of the range shown in Table 3a, the meter does no
meet specification.
