Table 3b DC mA Test:
Step Range Source Reading
1 40mA 30.00mA 29.80 to 30.20
2 400mA 300.0mA 298.0 to 302.0
Testing the DC ampere Function (for 61-340 and 61-342)
1. Connect the calibrator to the 10A and COM inputs on the meter.
2. Turn the rotary switch to the
position. Press the SELECT button to select the DC function
3. Apply the inputs for steps 1 - 2 in Table 3c.
4. For each input, compare the reading on the meter display to the reading for your meter in Table 3c.
5. If the display reading falls outside of the range shown in Table 3c, the meter does not meet
specification.
Table 3c DCA Test:
Step Range Source Reading
1 4A 3.000A 2.950 to 3.050
2 10A 9.00A 8.82 to 9.18
Testing the AC microampere 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 the
position. Press the SELECT button to select the AC function.
Press the REL button to make sure the display is zero.
3. Apply the inputs for steps 1 - 6 in Table 4a.
4. For each input, compare the reading on the meter display to the reading for your meter in Table 4a.
5. If the display reading falls outside of the range shown in Table 4a, the meter does not meet
specification.
Table 4a AC microampere Test:
Step Range Source Frequency Reading
1 400µA 40.0µA 60Hz 38.9 to 41.1
2 400µA 40.0µA 400Hz 38.9 to 41.1
3 400µA 300.0µA 60Hz 295.0 to 305.0
4 400µA 300.0µA 400Hz 295.0 to 305.0
5 4000µA 3000µA 60Hz 2950 to 3050
6 4000µA 3000µA 400Hz 2950 to 3050
