Extech DVA30 AC Volt / Current Detector Non-Contact Ac

four LR44 button batteries and pocket clip.

Detects and pinpoints wide range voltage and current with sensitivity adjust

• Current function detects live circuits through shielded wires, conduit and metal circuit breaker or junction boxes where voltage detectors cannot work
  
• Non-contact detection of AC voltage from 12VAC to 600VAC; detects AC Current from 200mA at 0.2" and larger current at greater distances
  
• Sensitivity adjustment increases or reduces sensor trigger threshold
  
• Dimensions / Wt: 7.6 x 1.2 x 0.9" (192 x 31 x 24mm) / 2.1 oz (60g)
  
• Audible and visual indicator of current or voltage
