1-3 Electrical Specifications

Accuracy is given as ± (% of reading + counts of least significant digit) at
23°C ± 5°C, with relative humidity Less than 80% R.H.,
and is specified for 1 year after calibration.
 Condition of Auto Power On :
With batteries fitted :
- > 3.0V or < -8.0V between L2 and L1
- Detect AC signal by Single Pole
- Continuity
Without batteries :
> | ±35.0V DC | or > 45.0V AC between L2 and L1
 Auto Power Off :
The Meter automatically turns off if one of the following
conditions are met for about 10 seconds
- The Auto Power On condition is not met.
- Both buttons are not pressed.
The Meter automatically turns off if one of the following
conditions are met for about 30 seconds
- The resistance is OL when the Meter is in Resistor mode.
- The current is < 1.0A when the Meter is in Ampere mode
 For > 300V, Time rating (tr): 30 seconds; Recovery time (rt):
240 seconds
 AC Function
- ACV and ACA specifications are ac coupled, true RMS.
- For non-sinusoidal waveforms, Additional Accuracy by
