MAINTENANCE
The unit does not require any routine maintenance. It may be necessary to perform periodic checks
of the calibration of the scale due to mechanical reasons. The frequency of the calibration checks
depends on the application condition and on the required measuring accuracy.
It may happen that, in exceptional conditions, the unit locks on a wrong memory location and it is not
possible to restart because the keyboard is not operative.
To restart it is necessary to switch the power OFF then ON again.
9.4. SERVICE
There are no serviceable parts. The unit may be repaired by trained personnel only.
The user may check cable connection(s) and power supply.
