The Core is 12 A / D converter microcontroller, high accuracy, wide measuring range (30 V ~ 400V). When Measure value exceeded the scope of value, the light will flashing as alarm (set aside the interface for alarm buzzer). Three settings buttons, you can set the maximum and minimum.

Can be get Power directly from the testing, and only 2 wires can be normal work and will be able to access accurate testing, no need match with low-voltage power adapter. Buttons can control the decimal point position, set measurement range, precision.

Conditions of Use: -20 degree to 85 degree, and relative humidity ≤ 80% (25 degree).
Voltage: Since the self rating change 15%, the error caused by it will not more than the basic error.
