Exchanging the battery
▪
It can be assumed that a 1.5 Volt battery will have a general service life of
approx. 5000 hours.
The voltage of the battery may be sufficient for normal use, but not for
measurements. In this case, the device will not take a measurement or provide
noticeably inaccurate readings.
Wide measurement discrepancies can be caused by a used battery.
In case of strong measurement deviations, the device should be calibrated with
distilled water after the battery has been exchanged,
and calibrating.
▪
If the error code "LLL" is shown on the display, the battery has to be replaced by a
new one.
