ERROR CODES
E02 Reading is under the lower range limit; See
page 67 for range specifications for all
parameters
E03 Reading is over the upper range limit; See
page 67 for range specifications for all
parameters
E04 Error in measuring original data (damaged
temperature sensor or temperature out of
specicifications) results in conductivity or pH
value error. E02 or E03 will also appear in the
temperature column. If E04 is caused by high
liquid temperature (E03), cool down the liquid
temperature.
E12 Factory calibration data error (pH); Restart
the meter
E13 Slope or Offset value of the pH probe is out of
range
E16 Factory calibration data error (conductivity);
Restart the meter
E17 Cell constant of the conductivity probe is out
of range; Restart the meter
E31 Measuring circuit failure; Restart the meter
E32 Memory Integrated Circuit failure
