Charging the Measuring Instrument
Temperatures and Ambient Conditions
The device heats up during the charging
process.
If the hand-held measuring instrument
only functions briefly or not at all despite
repeated charging, the built-in battery is
defective and must be replaced. Please
contact PERI if this is the case.
The specified maximum operating times
apply only under optimum conditions. The
ambient temperature and charging cycle
can significantly reduce performance
times. In addition, the charging capacity is
reduced due to technical reasons during
use or when stored in conditions with
very high or low temperatures.
