6. Place the calibrated weight in the middle of the weighing surface in one,
or at most two steps of equal size. The calibration weight required may
vary depending on the model (see Table 2).

7. Once a correct, stable weight value is identified, the LCD display will
stop flashing, and a calibration value will be calculated and stored. The
scale then switches off automatically shortly afterwards. If the LCD
display does not stop flashing, the measured weight is either above or
below the weight to be expected, or a stable weight value cannot be
established (due to vibration / shocks, etc.).
8. Then remove the weight from the scale, move the slide switch on the
PCB back to its original position and refit the display.
9. Now set up the scale again and switch on. Next, place a calibrated
weight on the scale and check the display for the correct weight value. If
manual calibration was successful, reseal the scale according to the
national regulations.
Note:
Automatic monitoring of the battery voltage is not possible during manual calibration. It
should therefore be checked before and after every calibration procedure. This can be
carried out by switching on the scale and observing the display. If the battery voltage is
insufficient, either the battery warning symbol or the "bAtt" display will be activated. If one
of these displays appears before or immediately after calibration, the batteries should be
replaced and the calibration procedure repeated.
Manual calibration can be aborted before placing the required weight on the scale by
switching off the device.
