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.

Safety standards:

Operating environment: Temperature 32 to104°F (0°C to 40°C), Humidity ≤ 80% RH.

Storage environment:

Power supply: One standard 9 volt battery (NEDA 1604, IEC 6F22 or equivalent).

Dimension: 165(H) x 83(W) x 36(D) mm

Weight: Approx. 360g (including battery).

2.2 ELECTRICAL SPECIFICATIONS

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

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.
