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

C±5°C, with relative humidity less than 80%RH. The precision index
mentioned above refers to the accuracy of 40%~60% range of each
measurement range. The accuracy index of the current measured outside
the measuring range increased by 1.5%, and the accuracy of other
measurement functions increased by 1%. Check waveform is sine wave.
Current accuracy assessment shall be based on the position of clamp center.
