Testing the Voltage Function (for 61-340 / 61-342)
To verify accuracy in the AC and DC voltage ranges, do the following:
1. Turn the rotary switch to the
position.
2. Connect the calibrator to the
and COM inputs on the meter.
3. Set the calibrator for the voltage in steps 1 - 7 in Table 1.
4. Compare the reading on the meter display with the display reading shown in Table 1.
5. If the display reading falls outside of the range shown in Table 1, the meter does not meet
specification.

1. Turn the rotary switch to the
position.
2. Set the calibration for the voltage and frequency in steps 1 - 10 in Table 2.
3. Compare the reading on the meter display with the display reading shown in Table 2.
4. If the display reading falls outside of the range shown in Table 2, the meter does not meet
specification.
