The clamp meter can be used to measure AC DC current/voltage, resistance, capacitance, diode, continuity,frequency, temperature. lt also includes functions like NCV, Live. MAX/MIN, HOLD, INRUSH, VFD, flashlight, backlight, automatic shutdown, full-range overload protection, low battery indication.

A dual-color molded housing with ergonomic soft rubber grip for superior comfort and slip resistance. The stylish two-tone design combines visual appeal with practical durability

AUTO-V LOZ Function
Turn the rotary switch to the AUTO-V LOZ position. The meter will enter low-impedance voltage auto-identification mode. In this mode, no manual conversion is required—the meter will automatically detect whether the measured voltage is AC or DC based on the input signal.

ZERO Function
To ensure the accuracy measurement. press the ZERO button in DC current mode to clear the base number caused by electromagnetic interference in the use environment. After zeroing, keep the same direction for measurement.

Correct Measurement
Only a single wire should be placed in the clamp for measurement and placing two or more wires simultaneously will result in incorrect readings. ensure the load is active during measurement.

Jaw Design
The jaws of the clamp meter can be opend up to 30mm (1.12 inch) suittable for various wire measurements, easily measure current, voltage.

Variable-frequency Measurement
Start VFDin AC voltage and current mode to effectively reduce high-frequency interference on measurement results.

Accurate Temp Measurement
Features a high-precision K-type thermocouple probe for fast, reliable temperature readings (-40°C to 1000°C / -40°F to 1832°F)

Large LCD wirh Backlight
The LCD Backlit Screen and Flashlight make it easy to use in a dark working area.

HOLD Function
"HOLD"can “freeze” the readings so you can record them. If you need to write down the readings for later use, a hold button is indispensable.
A USEFUL TROUBLESHOOTING TOOL
