Malfunction Possible Cause Remedy
Noisy Blocked junction on
reference electrode
Chloride or reference
electrode failure
Make sure electrolyte is flowing properly and
the bottle is pressurized by the air pump.
Check the cable connections and location of
wiring to terminal strip. Refer to Chapter II.
Temperature probe failure Disconnect ATC. Temperature should read
25 °C (E101). Replace if necessary.
Air pump failure Check the air flow for a steady stream of
bubbles in the flow cell and replace the air
pump if necessary.
Calibration standard
carryover
Disconnect the air pump intake tube. Rinse
the flow cell and electrodes with deionized
water by lifting the flow cell cap. Reconnect
the air pump.
Faulty electrode cables Replace electrode cables.
Excessive Drift Sample concentration

Chloride or reference
electrode failure
Reference electrode
filling solution empty or
incorrect solution used
Check sample status. Perform a span check
and if span check passes, the analyzer is okay.
Make sure electrolyte is flowing properly and
the bottle is pressurized by the air pump.
Check the cable connections and location of
wiring to terminal strip. Refer to Chapter II.
Use Cat. No. 100057F4 reference electrode
filling solution.
Temperature probe failure Disconnect ATC. Temperature should read
25 °C (E101). Replace if necessary.
Low Flow Rate Sample pressure below
8 psi
Pressure regulator set
too low
Check the sample pressure. If it is less than
8 psi, increase the pressure. Refer to
Chapter II.
Increase the pressure by pulling on the
red locking ring and turning the black knob
clockwise. Refer to Chapter II.
Inlet filter clogged Replace or clean the filter.
Restrictor tubing crimped
or clogged
Replace the restrictor tubing. Refer to
Chapter II.
