Acquisition of the standard values (calibration without a known weight)
- If you do not want to proceed with theoretical calibration, press 4 times.
- If you do want to calibrate the weighing unit without the use of a weight and with the help of the
factory data, enter the values printed inside the unit with the help of functions (X... , .X.. , ..X. , and
...X) and validate each value by pressing .

Testing the printed circuit voltages
Supply voltage of the electric battery (min. 12 V - max.
13.8 V)
Supply voltage of the CPU card (5 V +/- 0.5)
Contrasted power supply LCD voltage
(15 V +/- 0.5)
Sensor excitation voltage (8 V)
Supply voltage of the electric battery after protection
(min. 11 V).
Threshold of the Low voltage alarm.

SENSOR EXCITATION VOLTAGE
Refer to the electronic circuit board connection diagram.
- If the voltage is less than 7.5 V, disconnect all the sensors from the circuit board and read the
excitation voltage again.
- If this voltage is still less than 7.5 V, there is a problem with the circuit board: change the weighing
unit.
- If it returns to 8 V, connect the sensors one by one and check if the voltage drops each time the
sensor is connected. As soon as the voltage drops, this means the sensor that has just been connected
is faulty - replace it.
