EXTECH Non-Contact AC Voltage and Current Detector DVA30 User Guide and Manual
Summary
Advanced non-contact AC voltage and current detector engineered for electrical professionals. This versatile two-in-one tool helps trace concealed "hot" wires in conduits, walls, and fixtures. Capable of sensing voltage from 12V up to 600VAC and measuring high currents (up to 1000A), it provides critical visibility where standard detection fails. The accompanying documentation details setup, extended range testing, sensitivity adjustments, and multiple non-contact applications for reliable electrical troubleshooting and safety checking.

Frequently Asked Questions
What is the usable range for both voltage and current detection?
Voltage ranges from 12V to 600VAC, and current detects flow from 200mA to 1000A.
Can this device detect hidden wires or trace current through conduits?
Yes, it can trace concealed wires in walls/floors and detects current flow behind walls or in conduit.
Does the detector require physical contact with the circuit?
No, it is a non-contact AC voltage and current detector. It also detects current through shielded wires and junctions.
What special features are available for accurate reading?
It includes sensitivity adjustments to control the sensor's trigger threshold, an audible alarm, and a visible indicator.
