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.
