Calibration/Adjustment*
Always calibrate/adjust the scale after setting it up in a new
location.
Available Features
Calibration/adjustment can only be performed when
– there is no load on the scale,
– the scale is tared,
– the internal signal is stable.
If these conditions are not met, an error message
is displayed.
The weight required for calibration/adjustment is displayed.
Example
Calibrate the scale
Menu code settings: Factory-set codes
Step Key (or instruction) Display
1. Turn on the scale [ON/OFF]
2. Tare the scale t 0.000 ct
3. Begin calibration [CAL/CF] + 100.000
Calibration weight
is displayed without
weight unit (here: 100 g)
4. Place the indicated 100.000
calibration weight
on the scale
After calibration, the + 500.000 ct
calibration weight
is displayed with wt. unit
5. Remove the 0.000 ct
calibration weight
* “Calibration” technically means to determine the difference between
the scale readout and the actual weight on the pan to determine
the accuracy. Adjustment means to bring a scale into the state of accuracy
required for its use. Therefore, “calibration,” as used in this manual,
actually means “adjustment.”
Operating the Scale
Basic Weighing Function
Available Features
– Taring the scale
