4.3 Adjusting (calibrating) the scale
The scale was adjusted at the factory. However, we still recommend adjusting the scale when it is put into
operation for the first time, and thereafter at regular intervals, especially after a change of location.
Adjustment can only be done in service mode. Before doing the adjustment, the geo adjustment value
must be checked for correctness in the "GEO" menu block (see table in Chapter 7).

• In service mode call up the "CAL" menu block. With the b key
select "CAL YES" and then start the adjustment with the c key.
• Select the desired weight unit for the adjustment and confirm with
H9
the c key. The units available depend on the selected region (menu
block "CTY"): for the setting "EU" (Europe) only "kg" is available
while for the setting "GE" (USA) there is a choice between "kg" and
1B
"lb".
• Select the maximum capacity of the scale (this is printed below
the display, adjacent to the level indicator) and confirm it with the
c key. Note: The values in the display have a 1000x higher resolu-
tion, i.e. a displayed value of 6000 represents 6 k g or 6 l b (de-
pending on the unit selected previously) and a displayed value of
15000 represents 15 kg or 15 lb.
• The scale prompts you to empty the weighing pan. Remove any
loads on the pan and confirm this with the c key. The scale then
performs a zero setting during which a counter is displayed which
counts backwards from 5 to 1.
• After the zero setting, your are prompted to place an adjustment
weight on the pan which corresponds to 2/3 of the selected capa-
city (in this example 4 k g / l b , corresponding to 2/3 of the weigh-
ing capacity of 6 kg/lb). Confirm that the weight has been placed
on the pan with the c key. While the weight is being measured, a
counter is again displayed which counts backwards from 5 to 1.
• The scale now prompts you to load the weighing pan with the
adjustment weight which corresponds to the selected capacity (in
this example 6 kg/lb). Confirm that you have placed the weight on
the pan by pressing the c key. While the weight is being measured,
a counter is again displayed which counts backwards from 5 to 1.
• The adjustment is complete. Press the c key to save the result and
quit service mode. If you do not want to save the result, press b
and confirm the "Abort" message with the c key.
