VOLTAGE DETECTOR

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 Key Features • Top “primary supply level” safety class rating for voltage detectors • CAT IV 1000 V design meets CE Mark qualifications • Continuously indicate battery status with green indicator lamp • Both visual and audible voltage detection indication • Automatic power switching prevents battery discharge

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 Metalware 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.
