Possible measurements:
- earth resistance measurment with 3-pole method,
- measurement of continuity of equipotential bondings and protective conductors with auto-zero function - with current 200mA,
- resistance measurement using 2-pole method.
Additionally:
- AUTO-OFF function after 5 minutes,
- indication of battery state.
It allows to take:
- earth resistance measurement using auxiliary probes with 3-pole method,
- resistance measurement using 2-pole method,
- measurement of continuity of equipotential bondings and protective conductors (meeting the requirements of IEC 61557-4) with auto-zero function – with current 200mA.
Additionally:
- AUTO-OFF function after 5 minutes,
- indication of battery state.
