The reference
electrode does not
operate correctly.
There is a leak or
blockage in the
reactivation solution
tubing.
The reactivation
solution pump does not
operate correctly.
Solution
Make sure that the end of the reactivation solution
tube is at the bottom of the bottle.
Replace the reactivation solution. Refer to
Replace the calibration and reactivation solutions
on page 4.
• Make sure that the sodium electrode is
installed correctly. Refer to the installation
manual.
• Make sure that there is no air in the glass bulb
of the sodium electrode.
• Remove the reference electrode from the
measurement cell. Lift the collar that is on the
glass part to let some KCl electrolyte flow out.
Push the collar down and turn the collar less
than 1/4 of a turn to lock the collar. When the
collar is locked, the collar does not turn. Install
the reference electrode in the measurement
cell.
• Make sure that the reference electrode is
installed correctly. Refer to the installation
manual.
• To identify if the problem is fixed, push diag,
then select SENSOR REACTIVATION to do a
reactivation.
Look for a blockage or leak in the tubing. Replace
tubing as necessary.
Push diag, then select PERFORM TEST >
REACT SOL DELIVERY > HIGH to set the
reactivation solution pump to a high flow rate. If
reactivation solution does not flow to the middle
chamber of the measurement cell, replace the
reactivation solution pump.
