Key parameters
Fits tracing live wires when you need one pen-style tool for non-contact AC voltage and non-contact AC current presence, with separate indicators, without contacting conductors.
Key advantages
- Dual NCV + NCI — non-contact AC voltage (~12–600 VAC) and current (~200 mA–1000 A class).
- Separate indicators — distinct voltage and current LED/audible cues.
- CAT III 600 V — pen-style dual-function detector.
- No conductor contact — trace live wires and estimate current presence without clamping.
Typical applications
- Tracing live wires when both voltage and current presence matter.
- Quick panel scans before contacting conductors.
- Kits consolidating NCV and non-contact current into one pen.
Selection guide
- Type — Extech DVA30 non-contact AC voltage and current detector.
- Voltage — Non-contact AC voltage detection about 12 to 600 VAC.
- Current — Non-contact AC current detection about 200 mA to 1000 A class.
- Indication — Separate voltage and current LED/audible indicators.
- Safety / form — CAT III 600 V class dual NCV/NCI detector; pen-style body.
Common mistakes
- Expecting a calibrated amp reading — listed path is non-contact current presence (~200 mA to 1000 A class), not a clamp-meter measurement.
- Ordering DV30 when you need current indication — DVA30 adds the NCI path; DV30 is voltage-only on its extract.
- Treating separate LED/audible channels as simultaneous logging — they indicate presence.
- Ignoring CAT III 600 V when working on higher-category gear.

When to RFQ / what to tell us
- Need for dual NCV + NCI vs voltage-only (compare DV30).
- Voltage/current bands vs about 12–600 VAC and ~200 mA–1000 A class.
- Quantity, ship-to, CAT III 600 V confirmation.

FAQ
Q: How is DVA30 different from DV30? A: DVA30 adds non-contact AC current (~200 mA–1000 A class) beside AC voltage (~12–600 VAC). DV30 is voltage-only on its extract.
Q: Does it give a numeric amp reading? A: No — separate LED/audible indicators for voltage and current presence, not a clamp-meter amp value.
Q: What should I send for a quote? A: Dual NCV/NCI need, quantity, ship-to. Compatible with systems using Extech DVA30 — we do not claim authorized-dealer status.
