7 TROUBLE-SHOOTING
Troubleshooting 9032X
Problem Possible Cause(s) Solution(s)
Calibration Fail Empty or Contaminated
Standards Solutions
Container(s) Check to make sure
calibration standard bottles
are 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(s) Run Solenoid Check cycle in
Diagnostics – check status
and connections of
solenoid valves.
Calibration Fail Strength is too low. <83 Make sure both 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 (5mm
into 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 5.5.2 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.
