Adjusting the Device
Material Calibration and adjustment weight
Requirements
− The weighing pan is unloaded.
− The operating display shows a stable weight value.
− The external calibration and adjustment function is
set (see Chapter 7.2.2, page 32).
− The preset weight value for the adjustment weight or
the user-defined weight value for the adjustment
weight is selected (see Chapter 7.2.2, page 32).
Procedure
t Press the [Zero] button.
t Press the [Adjust] button.
t Place the indicated calibration and adjustment
weight on the balance.
y The weight value is displayed.
t If the calibration with subsequent automatic adjust-
ment function is selected and the adjustment weight
placed on the device is within the specified limits:
y The adjustment process starts.
y If the “+“ prefix is displayed: The applied weight is
too high.
y If the “–“ prefix is displayed: The applied weight is
too low.
y The “CAL.END.“ message indicates the end of the
calibration process.
t Remove the adjustment weight.
t If the calibration without subsequent automatic ad-
justment function is selected and the adjustment
weight placed on the device is within the specified
limits:
t Press the [Confirm] button.
y The adjustment process starts.
y If the “+“ prefix is displayed: The applied weight is
too high.
y If the “–“ prefix is displayed: The applied weight is
too low.
y The “CAL.END.“ message indicates the end of the
calibration process.
t Remove the adjustment weight.
8.6 Printing Results of the Calibra-
tion and Adjustment Process
The results of the calibration and adjustment process
can be printed in a GLP printout.
Procedure
t Set the GLP printout in the menu (setting parame-
ters, see Chapter 4.6.7, page 24).
t Adjust the device.

Weight Units” Function
The “Toggle between weight units” function enables to
switch between a maximum of four different units. The
selected basic unit is displayed every time the device
started (see “UNIT“ Chapter 4.6.8, page 25). The
units can be set during the weighing process and the
decimal places can be adjusted.
Requirements
The “Toggle between weight units” function is activated
(see Chapter 4.6.8, page 25).
The weight value must be valid.
Procedure
t To switch the displayed weight unit during weighing
or before an application: Press the [Unit change]
button until the desired unit is displayed.
y The current weight value is displayed in the selected
unit.
8.9.2 Selecting Convertible Units and their
Decimal Places
Procedure
t Press and hold down the [Unit change] button.
t Select one of the parameters “Unit 1“ – “Unit 4“ in
the submenu. To do this, press the [Confirm] button.
t Select the desired unit. To do this, press the [Con-
firm] button.

The “Statistics“ application saves up to 99 weight val-
ues and evaluates these statistically.
The following values are saved and exported:
− Number of components
− Mean value
− Standard deviation
− Variation coefficientSum of all values
− Lowest value (minimum)
− Highest value (maximum)
− Spread: Difference between maximum and minimum
Requirements
− A printer or a PC is connected and configured.
− The “STATIST.“ application is selected.
Procedure
t Place a sample on the weighing pan.
t To save the weight value: Press the [Confirm] button.
y The position of the saved value is displayed, e.g., “NO
1“.
y The recording of the statistics starts.
t Remove the sample on the weighing pan.
t To save the next value:
t Place a new sample on the weighing pan and
press the [Confirm] button.
t To switch between the display of the current weight
value, the number of saved components, and the cal-
culated mean in the results display: Press the [Up] or
[Down] button.
