WARNING
‣
If the incorrect time is set, this falsifies the result of the decay compensation. This could
result in a dangerous failure that cannot be diagnosed in the device.
8.9 Behavior in the event of low terminal voltage
8.9.1 General principles
If the terminal voltage is low, the available energy level may not suffice to make all
functions of the device available. To ensure a reliable measurement function, the following
measures are taken depending on the energy available:
• For devices with a display (optional): the background lighting of the display and the
Bluetooth function are disabled
• For devices without a display: the total available energy is always available to the
sensor
If the energy does not suffice to reliably guarantee the measurement function, an alarm
F801 "Increase supply voltage" is output and the sensor function is switched off.
