Manual calibration of scale
[874|875|876|877|878|952|956]
Manual calibration is activated using a sliding switch (SJ1) on the PCB (see Figure 5). It
is only accessible after breaking the seal and opening the scale. After changing the
switch position to 2 ("CAL"), the scale has to be switched on to start manual calibration.

The following steps are necessary to perform manual calibration of the scale:
1. Switch on the scale and check the battery charge (see note). Calibration
must not continue if the batteries are low!
2. Then switch the scale off and open the integrated display by releasing
the four screws after having removed the seals.
3. The position 2 ("CAL") must be selected with the slide switch on the
PCB, which is now accessible.
4. Then set up the scale properly and switch on.
5. Start-up of the scale is followed by the segment test and then a flashing
display showing the weight to be placed on the scale.
