Calibration of Scales seca
03.04.2013/JEG 7 (24) 30-34-00-864
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 unscrew the lower service lid after having
removed the seal.
3. Connect the two jumper contacts using a jumper.
4. Then set up the scale properly again 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.
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 1).
Model Calibration weight
335, 382, 384 10 kg
334, 384, 833, 834 15 kg
835 20 kg
383, 385 40 kg
Table 1: Calibration weights required
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.).
