Ac Accuracy
±(1.5% of reading + 5 digits); resolution 1 V
Dc Voltage
0 to 690 V DC
Dc Accuracy
±(1.0% of reading + 3 digits); resolution 1 V
Continuity
0 to 200 kΩ, guaranteed on <50 kΩ; audible tone
Low Impedance
12–250 V AC/DC; impedance <6 kΩ; two-handed low-Z testing
Fits two-pole voltage and continuity checks where you need an Extech VT30 covering AC to 480 V and DC to 690 V with low-impedance testing, polarity LEDs, and CAT III/IV 600 V safety.
Key advantages
- AC — 0 to 480 V AC; ±(1.5% + 5 digits); LCD step scale family
- DC — 0 to 690 V DC; ±(1.0% + 3 digits)
- Continuity — 0 to 200 kΩ; guaranteed on <50 kΩ; audible
- Low-Z — 12–250 V AC/DC; impedance <6 kΩ; two-handed low-Z
- Safety / build — CAT III 600 V / CAT IV 600 V; IP64 rubberized; flashlight; 2× AAA
Typical applications
- Electrician voltage presence checks.
- Continuity and polarity verification.
- Low-Z tests to reduce ghost voltage.
Selection guide
- Low-Z use — Ghost voltage situations
- CAT rating — Match installation category
- Flashlight — Dark panels
- Power — AAA batteries
Common mistakes
- Relying on low-Z on circuits that cannot tolerate load.
- Exceeding CAT III/IV 600 V limits.
- Single-handed misuse of two-pole tester.
When to RFQ / what to tell us
