General information and setup
After transporting the scale from a cold place to warm room let it rest for 15 minutes
without power supply to avoid damages at electronic components due to condensation.
Place the scale on a solid and level ground. Soft ground (carpet) or a table that bends if a
heavy weight is placed on the board, can cause wrong results.
The scale needs a power supply of 6V, either by the AC-adapter or by 4 * 1,5V battery.
If the adapter is plugged in, the power supply to the battery is disconnected. They can
remain in the scale, but also if used with rechargeable battery, there is no charge function.
Connect the display unit to the spiral cable that leads to the plateframe and fix the two
screws at the plug softly by hand. The metal mount can be used to place the display on a
wall, or to gain better visibility to the field of view of the LCD when the display is placed on
a table. When transporting the scale, we suggest to turn the wall bracket forwards to
create a protection of the LCD screen.

Keypad Functions
3.2.1
“ON/OFF” key
：
holding down
“ON/OFF” key untill the display shows “ON”,
then the current internal voltage, scale range, at last,
displays from “F----1” to
“F-----9” while performing a self-test. After a view seconds “0,0kg” appears.
The scale now is immediately able to be used for weighings of heavy materials like
parcels or persons, for this just place a weight on the platform. But please note that
after startup the scale needs a view minutes to reach its optimal operation
temperature and to adjust the electrical components properly. During this time, the
scale is not as accurate as it can be after about 15 minutes, especially for dosages
of tiny amounts. If the scale is going to be used several times each day, we suggest
to start it in the morning and keep it running with the display backlight on AUTO to
save energy (with deactivated LCD-backlight, the scales energy supply goes down
to about 0,5W and consumes
about 1 € of energy if one year never turned off).
To turn off the scale, hold down the
“ON/OFF” key till the display shows “OFF”, the
scale will turn off automatically.

the container, the scale shows a negative value of containers weight. Press
