Caution
Do not turn OFF the power supply or restart the Unit while the Set Bit is ON (data
is being written to the EEPROM). Otherwise, illegal data may be written in the
Unit’s EEPROM and “Special I/O Unit Errors” may occur when the power supply
is turned ON or when the Unit is restarted, causing a malfunction.
When making adjustments, be sure to perform both the offset adjustment and
gain adjustment.
Note
The EEPROM can be overwritten 50,000 times.
