Notes:
1
–
Occurrence of fault as "EEPROM Error"
–
the destruction of EEPROM indicates that the data of the programmed
parameters (Table 3.6) is damaged. To continue the operation, it is necessary to turn off UBZ and restore the factory settings
(5.2.7
–
second method).
2
–
Occurrence of fault as "Error CALIB"
–
UBZ improper calibration means that the calibration coefficients of the measured
data are damaged. The continued operation of UBZ is impossible. Re-calibration of the device is required to be done at the
manufacturer factory.
