7.8 Adjustment
As the standard gravity value is not the same in every spot on Earth, every display
with the scale plate connected should be adjusted, in line with the weighing rules
resulting from the laws of physics, to the standard gravity in the scale location
(provided the scale system has not already been subject to factory adjustment in its
location). Such an adjustment process should be carried out during the first start,
following every location change and also in the case of any ambient temperature
fluctuations. To ensure achieving accurate measurement date, it is also
recommended to carry out regular display adjustment also in the weighing mode.
•
Prepare the required adjustment weight, see chapter 1.
Whenever possible, adjust using the adjustment weight with the weight
similar to the maximum load of the scale (the adjustment weight is
recommended, see chapter 1). The adjustment may also be carried out using
weights with other nominal values or tolerance classes, but this is not optimal
from the measurement technique perspective. The adjustment weight
precision must correspond to the interval [
d
] of the scale, though preferably it
should be a bit higher. For information concerning reference weights, see
online at:
•
Ensure stable environmental conditions. The heating time is required for the
stabilization (see chapter 1).
•
Ensure there are no objects on the scale plate.
What to do:
Switch the scale on and when the autotest is carried out, press and hold the
button until the <
> is displayed.
Release the button . <
> and then the blinking symbol of the first
adjustment point will be displayed.
Using the
ZERO
button, select the required adjustment weight, see chapter 1
“Adjustment points” or “Recommended adjustment weight”.
Place the adjustment weight and confirm by pressing .
Wait until <
> is displayed.
Remove the adjustment weight.
Press . After the successful adjustment, the scale will switch to the weighing
mode again automatically.
If there is any adjustment error or if an incorrect adjustment weight is used, the
error message is displayed. Repeat the adjustment process.
