user by pressing the

CAL

button.

Before carrying out the internal calibration, ensure that no weight is loaded on the plate.

9.12.3 External calibration (E-CAL) [locked for verified balances]

The balance will be calibrated by using the external reference mass.

(Follow the procedures described in paragraph 8.1.2)

9.12.4 Technical calibration (TEC-CAL) [locked for verified balances]

This function allows the internal reference mass to be calibrated whenever assistance-control-
maintenance interventions make this necessary.

1. After having selected the

TEC-CAL

calibration mode, press the

CAL

button with the plate

empty. The word “CAL” will be displayed.

2. When the value of the calibration weight begins to flash, load the calibration weight on the

plate.

3. Wait for the calibrated weight to be displayed and the stability symbol to turn on, and then

remove the weight from the plate.

4. When

“0.000”

is shown on the display, press the

PRINT

button in a prolonged manner until

the beeping stops.

The acquisition and automatic storage of the internal weight will now

begin. During the acquisition cycle, the display will show the following flashing writing:
