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
converted and 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 have been integrated (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
higher voltage or higher current, it’s strongly recommended to install a power supply mod-
ule to not decrease the battery lifetime.
