Trouble
Remedies
Electrode Open!
Connecting cable is not
connected.
Check on connection
between the detection
electrode and stirrer.
Electrode cable is broken or
loosely connected.
Replace the electrode.
Electrode short!
When the electrode is
shorted.
Twin Pt pins of electrode are
in contact.
Correct the two pins to
extend in parallel.
It is over-titration.
Add water to polarize the
cell.
The tip of electrode is
cracked.
Replace the detection
electrode.
Over Titr!
Over-titration is underway.
Reagent with too much iodine
is cell.
Add water to the cell.
The titration cell is under
direct sunlight.
Refrain from direct sun’s
ray
or use a brown cell.
The anode is stained with
foreign objects.
Clean the inner burette and
the electrode.
Meas. Over!
When measurement exceeds
the range.
Change the catholyte.
Also change the anolyte if
necessary.
One time measurement
exceeds 300mgH2O.
Reduce sample size not to
exceed 300mgH2O, and try
again.
Current Error!
Sample liquid resistance is too
high or the electrode cable is
broken causing no current
flow for electrolysis in inner
cell.
Check on electrode
connection.
Reduce sample size.
Preamp Error!
Preamplifier circuit is now
defective.
Contact your local dealer.
