400mA 100μA
*15A 10mA
* A waiting period of at least 15 minutes is necessary between every 15
second testing period.
AC CURRENT TRMS
NOTE: Specifications are AC-coupled true RMS.
Range Resolution
40mA 10μA
400mA 100μA
Frequency response: 50 - 400 Hz
[1]
All ac ranges are specified from 1 % to 100 % of range.
Below 5 % of range, add 6 counts.
Because inputs below 1 % of range are not specified, it is
normal for this and other true-rms meters to display nonzero
readings when the test leads are disconnected from a circuit
or are shorted together. For volts and amps, crest factor of
≤3.
