Polarity: Automatic negative polarity indication.
Zero adjustment: Automatic.
Overrange indication: The "OL" or "-OL" display.
Low battery indication: Display "
Data hold: Display "DH" sign.
Relative measurement: Display "△" sign.
Auto Power Off: Display "APO" sign. When measurement exceeds 10 minutes without
switching mode and pressing key, the meter will switch to standby mode. Press any
key to exit standby mode. When restart the system, press and hold SELECT key to
disable auto power off.

2.2 ELECTRICAL SPECIFICATIONS

Accuracies are ± ( % of reading + number in last digit ), at 23 ± 5°C ,≤75% RH.

Overload protection: 600V DC or AC rms
Impedance: 10M ，More than 100M on 400mV range.
2.2.2 AC Voltage (
Range
0.4V,4V
40V,400V,600V
Impedance : 10M . More than 100M on 400mV range.
Overload protect:600V DC or AC RMS.
[1] All ac ranges are specified from 1 % to 100 % of range. Below 5 % of range, add 10 counts. （In
the range 400mV, an additional 2mV.）.
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 at 3000 counts, decreasing linearly to 2 at full scale.
AC volts and AC amps are dc-coupled.
If the measurement of AC voltage contains more than DCV 250V, please choose manual range
600V.
