3.3 Setup
The tension meter comes with a built-in rechargeable LiPo battery, which has been
charged at the factory. The tension meter can only be switched on if the battery is still
working, i.e. if the battery has enough charge. If the instrument does not power up or if
the battery level indicator shows only one bar
after power-up (Chapter 3.3.2), the
battery needs to be recharged.
To ensure maximum battery life, avoid discharging it completely or charg-
ing it frequently for short periods. The battery should not be stored for a pro-
longed time when empty. After a maximum storage period of one year, the
battery has to be recharged.

HANS SCHMIDT & Co. GmbH provides no warranty or liability for any
damage resulting from the use of AC adapters from other manufacturers.
To charge the battery, connect the cable of the AC adapter to the low USB output.
The battery can also be charged by connecting the USB cable to a PC.
When the battery is fully charged, the battery level indicator will show 3 bars
.
