2.1.4 Adjustment Mode and Displaying the Calibration Counter
Contents [284|285]
To begin readjustment or to display the calibration counter contents, start the
scale and press another key while the display shows seca. The contents of the
calibration counter (i.e. the number of adjustment procedures carried out so far)
are then displayed for 18 seconds (flashing).
While the calibration count is displayed, a key must be kept pressed (for more
than 1.5 seconds) to switch the scale to adjustment mode.
2.1.5 Placing Adjustment Weights on the Scale
[374|376|378|703|704|634|635|644|645|656|657|664|665|674|675|676|677|684|

Once you have switched to adjustment mode as described in section 2.1.3 or
2.1.4, the display shows the text “CAL”. By pressing any key except for the start
key for more than 1.5 seconds, the actual readjustment mode is activated. The
display reads "dec". The weight value currently measured then appears. The
scale is in decrementing state. To switch over from decrementing to
incrementing mode and vice versa press a key for more than 1.5 seconds with a
test weight placed on the scale. The display will read “dec” or “inc” accordingly.
The test weight is at least 25% of the max. load of the scale (we recommend
approx. 66-75%).
Adjustment can now be completed by pressing a key until the display shows
“Sto”. The scale computes and stores a new linearity coefficient and switches
off automatically. Your scale is now adjusted. Remove the test weight.
Note:
Timeout control is not active for the phase of placing and confirming the test weight.
To minimize adjustment errors, readjustment can only be carried out using a test
weight above 25 % and below 100 % of the max. load. Otherwise the error “Er:x:15”
will be displayed.
