9031CX Sodium Analyzer
Average factor: increasing the average factor will increase noise dampening and decrease
response time of the analyzer. Recommended Average factor = 80
Sensor data: this is a free text field up to 12 characters. The user may input the date of
exchange of a new sensor, the name of a sensor, etc.
Backlight Off delay: user may adjust the time the analyzer takes to turn off the backlight on
the display in order to save the life of the HMI screen / save energy. This may be from 0 min
to 120 mins.

TROUBLESHOOTING
3.6.1
CALIBRATION FAIL
A Calibration Fail condition will occur after a 2-Pt calibration if the electrode response does not
meet requirements. This happens when the electrodes “strength” (“slope”) from a 2-Pt calibration
is below 83 or greater than 110. This could be caused by a number of factors
3.6.1.1
Strength less than 83%

Make sure standard containers (CAL1 and CAL2) are full of solution.

Check that vapor bubbles are emerging from the bottom of the stainless steel entrainment tube
.

Check the condition of the reagent solution.

Regenerate the sodium measuring electrode. See Section Monthly maintenance
If the slope value is not improved after the sodium measuring electrode is regenerated, the electrode
may need to be replaced.
3.6.1.2
Strength more than 100%

Possible cause may be faulty reference electrode. Check status of reference electrode filling solution
and add more if using N3010-171A.

Check the status of reference electrode and replace if necessary.

Make sure standard containers (CAL1 and CAL2) are full of solution.
3.6.1.3
Very low or 0% slope

Check the operation of the solenoid valve(s).

Check flow of standard solution through flow cell.

Check the level of the salt bridge solution in the reference electrode, if using N3010-171A.

Check for open circuit reference electrode by substituting it with an electrode of known performance.

Check all electrical connections in the electrode junction box and interconnect cable.

Make sure standard containers (CAL1 and CAL2) are full of solution.

Make sure the low 100ppb standard is connected to Cal1 tubing and high 1000ppb standard is
connected to Cal2 tubing. Note that the high standard is red in color.
