Error
Probable cause
Action
Meter completely dead
No power supply.
Check the electrical connection.
Measurement value
fluctuates greatly
up and down..
Electrode not connected.
Check the connection.
Cable fault.
Check the cable.
Electrode without measurement water.
Check the flow cell
Incorrect measurement
values
(pH or chlorine).
Dirty electrode.
Clean the electrode.
Incorrectly calibrated meter.
Carry out calibration with fresh buffer solution.
Defective electrode.
Try shaking the electrode (if there is an air bubble
in the glass ball); otherwise replace the electrode.
Calibration cannot be carried Defective electrode
Replace the electrode.
Poor contact with the meter.
Check the cables, including the cables on the
inside connecting the BNC connectors on the out-
side with the circuit board.
Defect buffer solution.
Check the buffer solution.
Electrodes give sluggish
but correct value in buffer
solution but incorrect during
measurement
Dirty electrode.
Clean the electrode.
Electrode used up.
Replace the electrode.
Measurement value stuck at
pH = 7 and 0 mV or 0 mg/l
Short-circuit of measurement signal.
Check electrode, cables and connections.
Meter is not dosing, dosing
lamp is not illuminated or
AUTO is flashing.
Meter in “manual” mode.
Put the meter in “auto” mode.
“PHF” error.
Determine the cause and reset the alarm; chlorine
dosing starts when the pH value is correct.
The meter is not dosing, the
dosing lamp is illuminated.
Dosing equipment is not connected cor-
rectly.
Check connection
Dosing relay defective
Return the meter for repair.
Incorrect chlorine measure-
ment values
(Prominent measuring cell)
.
Air bubbles in the membrane.
Carefully tap on the outside of the electrode’s glass
casing or temporarily increase flow past the cell.
Dirty membrane.
Clean the membrane and fill with fresh electrolyte.
Pressure changes.
Depressurize the outlet from the flow cell.
Unstable pH value.
The pH value must be stable during chlorine mea-
surement; adjust pH to 7.4
Incorrectly calibrated meter.
Calibrate chlorine.
Chlorine value too low to be
adjusted to measured value
(Prominent measuring cell)
.
Poor electrolyte.
Replace the electrolyte or wipe off the gold tip of
the measuring cell with a napkin.
Oxides on the gold tip of the
measuring cell.
Carefully polish with wet grinding paper.
Incorrect chlorine measure-
ment values
(PB-200 measuring cell)
.
Test water flow too low.
Ensure that the flow through the measuring cell is
correct.
Unstable pH value.
The pH value must be stable during chlorine
measurement; adjust pH to 7.4
Incorrectly calibrated meter.
Calibrate chlorine.
Water sample contains high content of
isocyanuric acid.
Dilute or replace the pool water with fresh water.
Chlorine value shows zero all
the time
(PB-200 measuring cell)
.
Cable connection to metal cylinder loose. Fasten the cable connection.
No “click” during dosing;
dosing lamp is illuminated.
(Frequency controlled dosing).
Dosing relay defective.
Return the meter for repair.
