voltage detector BE20
Information about the device
Device description
The bipolar voltage detector serves to indicate voltage ranges
between 12 and 690VDC or 12 and 400VAC. The voltage
amounts are displayed in
8sections on an LED display with their polarity being indicated.
The device may be used in facilities of overvoltage category 3
(CAT III = domestic installations).
The device is further equipped with a torch for easier voltage
detections on poorly lit areas.
