DETECTOR DE TENSÃO 3120

Non-Metallic Contact Voltage Detector with Battery Life Indicator

Hioki leads the industry in non-metallic contact test and measurement technology that promotes safety on the worksite. The 3120 is a non-metallic contact voltage detector with a power switch that also gives a clear indication of the battery state with a green LED. When voltage is detected, the LED lights red along with an audio signal.

CAT IV 1000 V

Características principais

If a malfunction is suspected

Although the following phenomena, which are unavoidable in the detection principle, can be observed, the instrument has no malfunction.

・Phenomenon
The instrument incorrectly detects metalware including steel desks as live.
・Cause
Metal-ware close to AC power may charge AC potential (induced potential) to ground due to the influence of electrostatic capacitance, resulting in incorrectly detecting.

・Phenomenon
If the instrument is rapidly moved closer to or away from non-live circuits or DC circuits, the instrument detects live state temporarily.
・Cause
The non-live circuits or DC circuits may charge static electricity, temporarily resulting in incorrectly detecting.
