Battery life

The programming windows of the software provide you
with typical guide values for the expected lifetime of the
battery. This lifetime is calculated on the basis of the
following factors:
• Measuring cycle
• Number of connected sensors
Since the battery life depends on quite a few other factors,
the calculated data can only serve as guide values.
The following factors have a negative effect on the battery
life:
• longer flashing of the LEDs
• frequent reading out (several times per day) via the
SD-card
• extreme fluctuations in operating temperature
The following factors have a positive effect on the battery
life:
• display switched off
The battery capacity reading in the display of the data
logger is based on the calculated values. However, the
data logger is switched off when a critical voltage level has
been reached. It may therefore happen that:
• readings are still recorded, even though the battery
capacity reading says "empty".
• the measurement program is stopped, even though the
battery capacity reading just before indicated a still
remaining battery capacity.
In case of an empty battery or a battery change saved
readings will not be lost.
