Error description
Possible cause
Suggested remedy
E1
Response time failure. Calibration failed
to reach stability in 1 hour
Temperature unstable
Avoid draughts and direct
sunshine
E2
Zero calibration out of limits
Check limits ± 0.5 μA (±5.0nA)
Zero calibration not properly
performed
Repeat carefully
E3
Slope calibration out of limits
Check limits 40 to 200 %
Calibration not properly
performed
Wrong membrane thickness set
Repeat carefully
Check code 01
E4
Membrane failure
Perforated membrane
Replace and recalibrate
E7
Temperature too high
> 50 °C/122 °F
Process temperature too high
Wrong sensor programmed
Incorrect wiring
Check process
Check model code sensor
Check connections and
cable
E8
Temperature too low
< 0°C/32 °F
Process temperature too low
Wrong sensor programmed
Incorrect wiring
Check process
Check model code sensor
Check connections and
cable
E9
Cell current abnormal
Galvanic : outside -10 to 50 μA
Polarographic: outside -100 to 500 nA
Sensor fault
Programming fault
Check membrane
Check setup
E10
EEPROM write failure
Fault in electronics
Try again, if unsuccessful
contact Yokogawa
E12
Abnormal measured value.
The dissolved oxygen value (%sat.)
exceeds 150%. (or value set in Code 54)
Wrong DO sensor or
temperaure sensor
programmed.
Incorrect wiring.
Check code 01, 02, 10, 12
and 54.
Accurately perform
calibration.
E15
Cable resistance influence to temperature
exceeds ±7.5°C (±13.5°F)
Cable resistance too high
Corroded contacts
Wrong sensor programmed
Check cable
Clean and reterminate
