Power supply failure Promass 80
Lasting min. 1 power cycle:
• EEPROM saves measuring system data if the power supply fails
• HistoROM/S-DAT: exchangeable data storage chip with sensor specific data (nominal diameter, serial
number, calibration factor, zero point, etc.)
Promass 83
Lasting min. 1 power cycle:
• EEPROM and T-DAT save the measuring system data if the power supply fails.
• HistoROM/S-DAT: exchangeable data storage chip with sensor specific data (nominal diameter, serial
number, calibration factor, zero point, etc.)
Potential equalization No measures necessary.
