LRM-ST | HR-ST
Voltage indicator for capacitive measuring points
Voltage indicators type LRM-ST and HR-ST are portable parts of a voltage test system which are capacitively coupled to active parts with a single pole.
The display – and the entire function of the device – can be tested with the HR/LRM-ST function tester.
The device is subject to the periodic test prescribed in a cycle of 6 years in accordance with DGUV regulation 3 (table 1c).
Product features
- LRM-ST: Voltage indicator for low-impedance systems according to IEC 62271-213 and IEC 61243-5
- HR-ST: Voltage indicator for high-impedance systems according to IEC 61243-5
- Voltage display via flashing LED
- Also suitable for permanent operation on socket modules
