The following settings are necessary to operate the
device togetherwith connected components:
−Set up the communication of the connected devices
−Set up additional components
The following settings are recommended to set up the
device:
−Set the menu language
−Set the date and time
−Set the calibration and adjustment
Procedure
t Press the [Menu] button.
t To adjust settings: Open the desired menu.
t Select and confirm the desired parameter
(parameters, see Chapter “7.3 Parameter List”,
page 19).
t Exit the menu.
7.2 Setting the Calibration and
Adjustment
7.2.1 Setting Internal Calibration and
Adjustment (Only Model I-1x)
The following functions can be set for the internal
calibration and adjustment:
−Internal calibration with automatic start of the
adjustment.
−Internal calibration with manual start of the
adjustment.
Procedure
t Open the “SETUP”/”BALANCE” menu. Call up
the “CAL.JUST.” parameter and select the value
“CAL.INT.”.
t If the calibration function needs to be set with
subsequent automatic adjustment: In the
“SETUP”/”BALANCE” menu, for the “CAL.SEQ.”
parameter, select the “ADJUST” setting value.
t If the calibration function needs to be set without
subsequent automatic adjustment: In the
“SETUP”/”BALANCE” menu, for the “CAL.SEQ.”
parameter, select the “CAL./ADJ.” setting value.
7.2.2 Setting the External Calibration and
Adjustment
The following functions can be set for the external
calibration and adjustment:
−External calibration with manual start of the
adjustment.
Procedure
t Open the “SETUP”/”BALANCE” menu.
t If the calibration function needs to be set with
subsequent automatic adjustment: Select the
“ADJUST” calibration value for the “CAL.SEQ.”
parameter.
t If the calibration function needs to be set
without subsequent automatic adjustment:
Select the “CAL-ADJUST” calibration value
for the “CAL.SEQ.” parameter.

Parameter Setting values Explanation
AMBIENT V.STABLE Sets the ambient conditions to “very stable”: Activates a fast change in
the weight values in the event of a load change with a high output rate.
Recommended for the following work environment:
−Very stable table near the wall
−Closed and calm room
STABLE* Sets the ambient conditions to “stable”. Recommended for the following work
environment:
−Stable table
−Slight movement in the room
−Slight draft
UNSTABL. Sets the ambient conditions to “unstable”: Activates the delayed change in
weight values with a reduced output rate. Recommended for the following work
environment:
−Simple office desk
−Room with moving machinery or personnel
−Slight air movement
V.UNSTBL. Sets the ambient conditions to “very unstable”: Activates a significantly delayed
change in the weight values and long wait for stability with a further reduction in
the output rate.
Recommended for the following work environment:
−Noticeable and slow floor vibrations
−Noticeable building vibrations
−Weighed goods moved
−Very strong air movements
APP.FILT. FINAL.RD.* Activates a filter that enables a fast change in the display for very fast load
changes. Display changes with minimal load changes (in the digit range) occur
more slowly.
FILLING Activates a filter that enables a very fast change in the displaywith minimal load
changes, e.g. when filling containers.
STAB.RNG V. ACC. Sets the stability to “very accurate”.
ACC.* Sets the stability to “accurate”.
FAST Sets the stability to “fast”.
V. FAST Sets the stability to “very fast”.
ZER./TAR. W/O STB. If the button is pressed: The function of the [Zero] or [Tare] button is executed
immediately.
W/ STAB.* The function of the [Zero] or [Tare] button is only executed after stability is
achieved.
AUTOZER. ON* Activates automatic zeroing. The display is automatically set to zero in case of
a deviation of 0 less than (X).
OFF Deactivates automatic zeroing. Zeroing must be triggered with the [Zero]
button.

−The device displays the weight in the selected unit.
−The availability of units depends on national legislation and is therefore
country-specific.
DISP.DIG. ALL* “Show all decimal places”: All decimal places are shown in the display.
The setting change is not available on conformity-assessed devices.
MINUS 1 “Last decimal place off”: The last decimal place is switched off.
CAL./ADJ. EXT.CAL. The [Adjust] button starts an external calibration and adjustment process with
the preset calibration weight.
E.CAL.USR. The [Adjust] button starts an external calibration and adjustment process with
the user-defined calibration weight value.
REPRO Starts the reproducibility test. Determines the current calibration frequency
with a user weight.
SELECT The interface [CAL] is assigned a selection of permitted menu items from
“CAL./ADJ.”
INT.CAL.* The [Adjust] button starts an internal calibration and adjustment process.
CAL.SEQ. ADJUST* The adjustment starts automatically after the calibration.
CAL.-ADJ. The adjustment must be started or exited manually after calibration with the
[Confirm] button.
ON Z/T ON* Activates the initial taring/zeroing. The device is tared or zeroed after it is
switched on.
OFF Deactivates the initial taring/zeroing: After it is switched on, the device shows
the same value as before it was last switched off.
EXT.CAL. UNLCKED* Activates the external calibration/adjustment function under [CAL./ADJ.].
LOCKED Deactivates the external calibration/adjustment function under [CAL./ADJ.].
