3. The position 2 ("CAL") must be selected with the slide switch on the
PCB, which is now accessible, or with older models, the two jumper
contacts have to be connected using a jumper.
4. Then set up the scale properly and switch on.
5. After start-up of the scale the segment test is followed by a flashing
message on the display reading "LOAd".
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 3).

7. Once a centred load is identified on the weighing surface, the display
will read "CAL L". A few seconds later it starts to flash, showing the
weight to be placed on the scale.
Note:
If the display reads "CAL E", a corner load has been identified. In this
case the weight must be removed and the procedure aborted by
switching off the scale. Check correct set-up of the scale and repeat
linear calibration (from item 4.)
8. The weighing value displayed should now be acknowledged by briefly
pressing any key (except the Start key). Once a stable weight value is
identified, the LCD display will stop flashing, and a calibration value will
be calculated and stored. Shortly afterwards the LCD display will read
"Sto", and the scale switches off automatically a few seconds later.
9. Then remove the weight from the scale, move the slide switch on the
PCB back to its original position or remove the jumper and reassemble
the display housing.
