What to do if Megger Measuring Instruments show 'ERR 115'?
- LLeah CampbellJul 28, 2025
If your Megger Measuring Instruments display 'ERR 115', it could mean that both the main battery module and the backup battery are completely drained. To resolve this, recharge the main battery or replace it with a charged one. Then, switch the instrument on; the calibration constants will be retrieved from EEPROM.
