Typical approximate values for the expected battery life are included
in the programming windows of the software. These values are
calculated on the basis of the following factors:
- Measuring rate
- Number of probes connected
- Status led (green LED) activated/deactivated
The calculated data is only an approximation since the battery life
depends on many additional factors.
The following factors have a negative influence on the battery life:
- Alarm LED flashing for longer periods of time
- Frequent reading out (several times a day)
- Strong fluctuations in operating temperature
The following factors have a positive influence on the battery life:
- Deactivated Status led (green LED) particularly in the case
of extended measuring rates
The battery capacity displayed is based on calculated values.
The data logger can be switched off if a critical power level has
been reached. The following could occur:
- The logger continues to take readings although the display
indicates that the battery capacity is "empty".
- The measuring program is stopped even though the battery
capacity display indicated a short time previously that
battery capacity was available.
Saved readings are not lost if the battery is spent or
changed. Requirement:
The battery is changed by following the directions in the
Instruction manual.
