Machine weight: 190g Features: 1. The clamp head can open up to 32mm and the large jaw design can measure 600A current 2. Automatic shutdown, automatic shutdown after 15 minutes of no operation (can be canceled manually) 3. Use temperature sensing line to measure liquidairsurface temperature 4. NCV non-contact voltage induction, when the front of the meter is close to the line with voltage, it will emit a continuous alarm sound prompt (TA811B, TA811C) 5. For voltage measurement, press the voltage button lightly, and the screen will display the voltage value 6. For AC current measurement, pull the trigger to open the jaws, and place the clamp meter around the conductor to be tested, and the display will display the current value (when the current is greater than 3A, the backlight will turn orange) Function: -True RMS -Continuity test -Diode test -Data retention -MaxMin Mode -Low battery prompt -Relative value -FlashlightBacklight -Automatic shut-down Package list: - Host x 1 - Test lead x 1 - Cloth bag x 1 - Instructions x 1 - Thermocouple x 1 (TA811C)
