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
has enough charge. If the instrument does not power up or if the battery level indicator
shows a low charge
after power-up, the battery needs to be recharged.
To ensure maximum battery life, avoid discharging it 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
The battery can only be charged at a temperature b5 °C and +45 °C.
Before you connect the AC adapter, verify that the supply voltage is correct
(100 V – 240 V).
To charge the battery, remove the rubber stopper from the USB interface. Then connect
the AC adapter cable to the USB output. The battery can also be charged by connecting
the USB cable to a PC. The battery level indicator will be shown full
when the
battery is fully chaarged. The charging time is approx. 3 ½ hours (using the AC adapter).
NOTE:
Battery overcharging is not possible
3.2 Switching the tension meter on
1. 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. If the
tension meter does not display zero, perform a manual zero adjustment procedure
(see section 5.1).
NOTE:
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. Otherwise, the
automatic zero adjustment will be faulty.
3.3 Switching the tension meter off
Automatic switch-off (if enabled): After an idle period of 3 minutes, the tension meter
switches off.
Manual switch-off: Press and hold the button for 5 seconds.
