Product Overview

The DVA30 is the only two-in-one current/voltage detector designed for electrical testing. It detects AC voltage from 12-Volt to 600Vlt and AC current from 200 mA at 0.2 in. distance and at much greater distances for larger current flow up to 1000-Amp. sensitivity adjustments increase or reduce sensor trigger threshold. Audible and visual indicators show the presence of current or voltage. It can be used to trace concealed wires in walls and floors, identify hot wires, trace current flow where voltage detection does not work (behind walls, in conduits, through concrete, or underground). The sensitivity is high enough to trip on Low-Voltage HVAC or similar signal levels. Complete with four LR44 button batteries and pocket clip.

I'd like to measure the voltage & current to be delivered to (i.e. at the outlet) and running through a #6 or #8 3- or 4-wire flex cable adapter before plugging into my car. Will this do that? I don't want to have to expose the individual wires to use a "clamp-type" meter.

Thank you

Answer: 
No, it will not measure the voltage or current. It will only detect that is is a voltage or current in the cable. It will only detect current if the current is flowing.
