Battery Status – StatusOfBattery
Figure 8: System function StatusOfBattery
Function
StatusOfBattery
Description
Checks for the status of the battery and measures the battery voltage level.
Attention: During the check the battery will be unloaded for a very short time, e.g. it results in a little
discharge. This is the reason why this function should not be called periodically, but from time to
time only.
