Problem
Deviation of the cell constant
value higher than 30 % of its
nominal value.
Unstable reading for more
than 60 s.
1st, 2nd or 3rd standard
have the same nominal
value.
Incorrect standard solution.
Standards temperature.
Problem
Measured value out of range
Measured temperature value
out of limits.
Measured value out of the
programmed limits.
Activation of the alarm relay.
Temperature Coefficient
selected, TC = 0
Salinity measurement with
TC=0
Possible causes
Cell "worn out".
Error in the selection of the cell.
Verify programming
Defective or dirty cell.
Standard at temperature different from ambient.
Same standard was used for both calibration
points.
Press ESC to quit calibration.
The standard used is not among the 3 in memory:
147 µS/cm, 1413 µS/cm or 12.88 mS/cm. at
25 °C. Press ESC to quit calibration.
Standard temperature > 35 °C or < 10 °C.
Possible causes
Conductivity reading > 200 mS/cm.
After 10 minutes, the current output will remain
fixed at 22 mA, the alarm will activate and the limit
relay will deactivate.
Pt 1000 probe broken or temp. < -20 or >150°C.
Verify the programmed limit values.
Verify process evolution.
The programmed relay lag for activation of the
alarm relay has been surpassed.
Current output will remain fixed at 22 mA. and
the limit relay remains activated.
Measurement configured as salinity. Impossible
to measure with TC=0. The instrument proposes
autimatically TC=2.
TC=0 has been programmed. To measure
salinity, modify the TC.
