1.4 Indications and meaning of symbols
Terminal voltage monitor
The terminal voltage monitor displays on-line the voltages on the test terminals and information about
active test terminals in the AC installation measuring mode.
The voltage applied is displayed by means of the testing terminal symbol. All three
testing terminals L, N and PE are used for the selected measurement.
The voltage applied is displayed by means of the testing terminal symbol. The
testing terminals L and N are used for the selected measurement.
The testing terminals L and PE are active testing terminals. The testing terminal N
should be connected as well in order to have a correct input voltage.
The polarity of the testing voltage applied (R LOW, R ISO) is displayed at the
output terminals L and N.
Battery indication
Battery capacity indication.
Low battery.
The storage battery charge condition is too low to ensure correct measuring results.
Recharge the storage batteries or replace the batteries.
Charging in progress (if power supply adapter is connected).
Messages
Measurement is running, consider displayed warnings.
Conditions on the input terminals allow starting the measurement; consider other
displayed warnings and messages.
DC VOLTAGE! Warning!
Too high DC voltage (> 50 V DC) applied to the testing terminals!
Conditions on the input terminals do not allow starting the measurement, consider
displayed warnings and messages.
RCD tripped-out during the measurement (in RCD functions).
Portable RCD selected (PRCD).
Instrument is overheated. The measurement is prohibited until the temperature
decreases under the allowed limit.
RCD of type EV (Electric Vehicle)
RCD of type MI (Mobile Installation)
Result(s) can be stored.
High electrical noise was detected during measurement. Results may be impaired.
L and N are changed.
