6 Calibration
Electronic balances take mass measurements making use of gravity (g). Different
latitude and in geographic areas and altitude will vary gravity acceleration value (g).
Therefore, for accurate measurements, the balance must be adjusted to the local
environment. This adjustment is accomplished by the calibration function.
6.1 External calibration balances
6.1.1 External calibration
Calibration is accomplished by pressing CAL button.
1. Press CAL button when pan is empty, dashes are displayed on the display.
2. When calibration weight value starts to flash, load the weight on the pan.
The display will stop
flashing, indicating
calibration weight
value.
Once the calibration
is effected will be
shown the value of
the calibrated weight
and the current unit
of measure.
3. Unload calibration weight from the pan. The
balance is ready for weighing operations.
NOTE: if there is interference during calibration process, an error message will be displayed.
Moreover, it is
possible to
calibrate the
balance with a
calibration weight
higher than the
one set by default:

11
1. Press and keep CAL button pressed with empty pan until the acoustic alarm stops,
then release the button. On display it will be visualized the string "-CAL-", followed by
flashing string "LOAD".

ht equal higher or lower than default calibration weight; the balance will recognize it
as valid weight if equal or higher than calibration weight as long as it is a whole
number in comparison with the most meaningful digit of calibration weight.
e.g.: if calibration weight is 200g, it will be possible to calibrate the balance with
values from 100g 200g, 300g, 400g up to the highest limit of balance weighing
range.
The message“LOAD” on display will stop flashing. Once calibration has been
effected, the value of calibrated weight will be displayed.
3. Unload calibration weight. The balance is ready for weighing operations.
NOTE: if there is
interference during
calibration process,
an error message
will be
displayed.

6.2 Balances with internal calibration
6.2.1 Internal calibration
In these balance models there are 4 calibration modes:
From display zero condition, press and keep pressed the MENU button until the acoustic
alarm is over, then release the button. The message “unitS” will be visualized on display,
press then MENU button until you visualize “Calib” on display. Press PRINT to confirm.
1. Select the calibration mode you wish by pressing MENU button in sequence:
~AUT-CAL: auto calibration
~I-CAL: internal calibration
~E-CAL: external calibration
~TEC-CAL: technical calibration
2. Press PRINT button to confirm “AUT-CAL”, “I-CAL”, “E-CAL”.
To confirm “TEC-CAL” keep pressed the PRINT button until the acoustic alarm is
over.
3. After selection, the balance returns to calibration menu. Press and keep pressed
MENU button until the acoustic alarm is over, then release the button. Balance is
again ready for weighing operations.
6.2.2 Autocal ibration (AUT-CAL)
The balance auto calibrates through the internal reference calibration mass, after the
microprocessor has checked that no other weighing operations are being effected. In this
mode it is furtherly possible to effect calibration through reference internal mass by
pressing CAL button at any time, being sure first that there’s no weight load on the pan.
1. Press CAL button with no weight on the pan.
The message“CAL” will be displayed and balance calibration will be effected
automatically.
2. At the end of calibration, balance returns to normal weighing conditions.

13
If calibration is not finished due to vibrations or air flows, then the message “CAL
bUt” is displayed. Press again CAL button. If the problem repeats then select
external calibration and contact the product supplier.
6.2.3 Internal calibration (I-CAL)
The balance calibrates itself with internal reference mass ONLY on user command by
pressing CAL button.
Before effecting internal calibration, be sure that there’s no weight loaded on the
balance pan.
6.2.4 External calibration (E-CAL)
The balance is calibrated through an external reference mass (NOT provided with
models with internal calibration).
(Follow procedures described at paragraph 6.1.1)
6.2.5 Technical calibration (TEC-CAL)
This function allows storing the value of internal reference mass whenever checking or
assistance actions require it.
1. After having selected the TEC-CAL calibration mode, press CAL button at empty
pan. It will be displayed “CAL”.
2. When the value of calibration weight start flashing on display, load the weight on to
the balance pan.
3. Wait the
acoustic alarm
and that the
displayed
calibrated
weight value
stops flashing,
then unload
the weight
from balance
pan.
4. When string “0.000” is displayed continuously, then press and keep pressed the
PRINT button. This starts the internal weight value automatic acquisition and store.
During the acquisition cycle, the display will show “TEC-MEM”.
