TROUBLESHOOTING
Problem Possible Cause(s) Solution(s)
Calibration Fail Empty or Contaminated
Standards Solutions
Container(s) Check to make sure calibration
standard bottle is full, check calibration
tubing to make sure it is not pinched.
Replace calibration standard with fresh
solution and try again.
Calibration Fail Faulty Solenoid Valve Run Solenoid Check cycle in
Diagnostics
– check status and
connections of solenoid valve.
Calibration Fail Strength is too low. <83 Make sure containers of standard are
full of solution.
Calibration Fail Strength is too low. <83 Verify condition of reagent solution.
Replace monthly.
Calibration Fail Strength is too low. <83 Verify electrodes are connected
properly
Calibration Fail Strength is too low. <83 Check that vapor bubbles are
emerging from bottom of entrainment
tube.
Calibration Fail Strength is too low. <83 Ensure reference electrode tip is 42-48
mm from the top of the flowcell (5 mm
into the sample)
Calibration Fail Strength is too low. <83 Ensure calibration standard is flowing.
Perform Solenoid Check cycle in
Diagnostics to verify.
Calibration Fail Strength is too low. <83 Regenerate the sodium measuring
electrode. See section
Monthly
maintenance in manual.
Calibration Fail Strength is too high. >110 Make sure both containers of standard
are full of solution.
Calibration Fail Strength is too high. >110 Check level of reference electrode salt
bridge solution; add more if necessary
Calibration Fail Strength is too high. >110 Faulty reference electrode. Replace
with one of known performance.
Calibration Fail Strength is close to zero. Make sure both containers of standard
are full of solution.
Calibration Fail Strength is close to zero. Ensure there is flow of standard
solution through flow cell.
Calibration Fail Strength is close to zero. Check all connections from electrodes
to pre-amp box
Calibration Fail Strength is close to zero. Verify operation of solenoid valve.
Calibration Fail Strength is close to zero. Check level of salt bridge solution in
reference electrode.
Calibration Fail Strength is close to zero. Faulty reference electrode. Replace
with one of known performance.
