The internal sample counter is active in On mode and is reset if the sensor is turned off without the charger connected. All readings sampled when the counter was active can be seen in User Interface Program UIP-P.
- Page 9 Tips before a measurement • If possibly do the measurements without the charger connected. • Start the measurement with a fully charged battery. • Select a sampling interval without overwriting samples. Note! • If the sensor is turned off without the charger connected the sample counter is cleared.
