HR-ST

Voltage indicators type HR-ST and LRM-ST are portable parts of a voltage detection system, which are single-pole capacitively coupled to active parts. The test of the display – and the entire function of the device – is possible with the function tester HR / LRM. According to DGUV regulation 3 (table 1c), the device is subject to the repetition test prescribed in a cycle of 6 years.
