5. Check the 10V/5V output, and then turn bit 04 (the Set Bit) of CIO word
n+1 ON and then OFF again.
While the Gain Bit is ON, the gain value will be saved to the Unit’s EE-
PROM when the Set Bit turns ON.

(data is being written to the EEPROM). Otherwise, illegal data may be written
in the Unit’s EEPROM and “EEPROM Errors” may occur when the power sup-
ply is turned ON or when the Unit is restarted, causing a malfunction.
!Caution When making adjustments, be sure to perform both the offset adjustment and
gain adjustment at the same time.
Note The EEPROM can be overwritten 50,000 times.
