Features:
The 4000counts is a pocket-sized 3 3/4-digit automatic digital instrument with stable performance, high precision, high reliability, clear reading and overload protection.
Driven by AAA 1.5V battery, the instrument adopts LCD display and adopts boost power supply.
Even at the edge of 2.3V low battery, it can ensure the ultra-high brightness of backlight and flashlight.
This watch is easy to carry and is a meter that users like very much.
The backlight can be turned on and off automatically after 15 seconds.
This series of instruments can be used to measure DC voltage and AC voltage, AC current 600A, resistance, continuity test, frequency measurement and true RMS.
It is a superior tool and instrument, laboratory, factory, radio enthusiasts and the ideal tool for the family.

Notes:
1. When measuring voltage, please do not input the limit voltage exceeding the effective value of DC 1000V or AC 750V;
The voltage below
2.36V is a safe voltage. When measuring higher than 36V DC and 25V AC voltage, check whether the test leads are in reliable contact, are connected correctly, and are well insulated to avoid electric shock;
3. When changing functions and ranges, the test leads should leave the test point..
