Main highlights

True-RMS clamp meter: This multimeter can accurately measure AC/DC 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. Easy to use for labs factories and household.

NCV Detection Function: Non-contact voltage detection effectively check electrical status through measuring EM field intensity without touching any wires; The NCV button lies on the right side. Simply place your thumb on it and push.

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 transformer. To measure the current you need to clamp the meter around one of the wires and not the whole power cord.
