Digital AC Clamp Meter

True-rms clamp meter: this voltage meter can accurately measure ac current, ac/dc voltage, frequency or duty cycle, resistance, capacitance and also provides diode, continuity, and temperature tests. True rms for accurate measurements on non-linear loads. Lowz & lpf: low input impedance helps prevent false readings due to ghost voltage. Low pass filter (lpf) for accurate measurement of variable frequency drive signals when measuring motors and transformers. To measure the current you need to clamp the meter around one of the wires and not the whole power cord. Ncv defection function: non-contact voltage detection effectively check the electrical status by through measuring em field intensity without touching any wires. Multi-function: two-color backlit lcd display - when the voltage is > 80v, the current is > 3a, the lcd backlit screen turns red to warn you of high voltage. Package included: 1 x kaiweets digital clamp meter, 1 x test leads (pair), 1 x thermocouples (pair), 2 x aaa batteries, 1 x user manual, 1 x carrying bag.
