3.3 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 (Chapter 3.3.2), 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 exten-
ded period of time when empty. After a maximum storage period of one year,
the battery has to be recharged.
3.3.1 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).
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 5 bars
.
The charging time is approx. 3 ½ hours (using the AC adapter).
Battery overcharging is not possible
3.3.2 Switching the tension meter 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 chapter
3.5.2).
Holding the
button makes the display freeze so that you can read the measuring
range and the software and hardware versions.
While switch-on the tension meter, make sure not to move it. Otherwise, the
automatic zero adjustment will be faulty.
3.3.3 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.
