3.0 SETUP
The tension meter is delivered 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 switching the tension
meter on, the battery needs to be recharged.
NOTE: To ensure maximum battery life, avoid discharging the battery completely or
charging it frequently for short periods. The battery should not be stored for a extended
period of time when empty. After a maximum storage period of one year, the battery has
to be recharged.
3.1 Charging the Battery
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 5 bars . The charging time is
approx. 3 ½ hours (using the AC adapter).
NOTES: It is not possible to overcharge the battery. The battery can only be charged
at a temperature between +5 °C and +45 °C. Before you connect the AC adapter, verify
that the supply voltage is correct (100 V – 240 V).
3.2 Switching the tension meter ON and OFF
To switch ON
Press and hold the button (for approx. 1 sec.) until the DISPLAY shows the
measuring range, the software and hardware versions, e.g. E 1.0, and then “0”. During
startup, the tension meter performs an automatic zero adjustment (see Section 5.3).
Holding the button makes the display freeze so that you can read the measuring
range and the software and hardware versions.
While switching on the tension meter, make sure not to move it. This will
cause the automatic zero adjustment to be faulty
To switch OFF
Automatic Switch Off : After 3 minutes of non-use the tension meter will switch off.
Manual Switch Off : Press and hold the button for ve seconds.
