VOLTAGE DETECTOR
3120

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.
