GENERAL SPECIFICATIONS
Clamp size
opening approx. 35mm
TRMS
The AC voltage and AC current of this meter are meas-
ured 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 curent.
Diode Test
