Máy đo điện trở đất Sonel MRU-10
It allows to:
- measure earthing resistance using auxiliary electrodes,
- measurement of resistance of auxiliary electrodes RS and RH,
- measurement of interference voltage,
- measurement in the presence of interference voltage in the power network with frequency 50 Hz and 60 Hz,
- selection of maximum measuring voltage (25 V and 50 V),
- indication of battery state.
