The AC voltage and AC current of this
instrument are measured by TRMS. True RMS
measurement is different from mean
measurement. The mean measurement
method can only measure the symmetric
waveform, such as sine wave. True RMS
measurements can reliably measure any
irregular waveform and obtain valid values for
AC voltage or AC current.
Test current of 0.3mA typical; Open circuit
voltage 3.2V DC typical.
Threshold <=50Ω; Test current < 0.5mA
