7.4 Inserting and connecting the batteries
7.4.1 Overview of battery arrangement options
Three battery terminals are available in the measuring device. These terminals are assigned
different uses depending on the number and arrangement of the batteries.
B1 and B2 are the terminals for power supply to the measuring device, B3 is the terminal for the
GSM/GPRS modem.
The measuring device is initially powered by the batteries in terminal B2. If the voltage supplied
by these batteries becomes too low, the measuring device issues a message and switches
automatically to the battery in terminal B1.
If power is supplied to the measuring device externally and the power supply fails, the battery
in terminal B1 acts as a backup power supply.
The GSM/GPRS modem is always powered by the battery in terminal B3.
This is also the case if the measuring device uses an external power supply.
The batteries are not charged if an external power supply is used.
The current state of charge of the batteries can be read on the onsite display or in the
BATTS parameter.
