Instruction for use | Supercal 5
5.4 Power Supply at the Calculator
Supercal 5 can be supplied with either battery or external mains modules. These can be
retrofitted at any time.
5.4.1 Power Supply Modules
The mains module is equipped with a backup battery already installed.
5.5 Connecting Sensors
5.5.1 Pulse Input for Volume Counting
The Supercal 5 allows the connection of slow and fast flow sensors. For this purpose, two
specific filters are provided (normal or fast mode), which can be switched via the Superprog
software.

Terminal 9 is intended to supply a flow sensor up to Vmax = 3.6 V and Imax = 20 µA. For high
-
er voltage or higher current, it’s strongly recommended to install a power supply module to
avoid reduced battery lifetime.
