ANENG Intelligent Digital Backlit Clamp-On High-Precision Multimeter, Specification: ST182 with Temp Measurement Feature: 1. Small size, easy to carry, easy to use with one hand 2. The 36mm large jaw opening can be measured without touching or interrupting the circuit, Automatic range, intelligent and efficient operation, obtain scientific and accurate results 3. 400A AC current measurement: 40A~400A wide range measurement, suitable for various wires, convenient and accurate 4. NCV non-contact voltage detection: If you want to detect whether there is AC voltage or electromagnetic field in the space, you can put the front end of the clamp head of the meter close to the measured object, if there is, a buzzer will sound and the NCV light will flash 5. Data retention function: keep the measurement data, easy to view or observe the data 6. Backlight function: LCD screen with backlight, which can clearly display data 7. Low voltage reminder: When the low battery symbol appears, the battery needs to be replaced in time. Insufficient battery may affect the accuracy of the measurement results 8. Automatic shutdown: if there is no operation within 15 minutes, the meter will automatically shut down 9. Multi-function measurement: ACDC voltage, AC current, resistance, capacitance, frequency, temperature, NCV test, diode, continuity test Specification: 1. Product material: ABS 2. Wire: Brass+PVC 3.
