The pH reading does not
match the Taylor kit test
measurement
The pH calibration is
failing
The ORP reading does
not match the chlorine
and pH measured values
No ORP reading (- - -)
The ORP calibration is
failing
•The sensor needs to be
cleaned, see section 6
•The sensor
measurement is drifting
and needs to be
calibrated
•The sensor is subject to
stray current
•The sensor needs to be
cleaned, see section 6
•The sensor needs to be
calibrated
•The sensor is broken

•The cyanuric acid
concentration in the pool
is too high (> 70 ppm)
•The ORP sensor is
disconnected from the

•The pH sensor is
connected instead of the
ORP sensor
•The measured ORP is
lower than 50 mV

ENGLISH
•Clean the sensor
•Proceed to calibration
of the pH sensor (see
process page 13)
•Check that the bonding
lug is connected
•Clean the sensor
•Proceed to calibration
of the pH sensor (see
process page 13)
•Replace the pH
sensor
•Clean the sensor
•Proceed to calibration
of the ORP sensor (see
process page 13)
•Check that the bonding
lug is connected
•Reduce the cyanuric
acid concentration in the
pool by draining it (or part
of it)
•Check that the red BNC
connector (ORP) is
connected to the right
BNC on the electronic
circuit board
•Check that the sensors
are not mixed, and the
color code is matching
•Clean the sensor and
calibrate it
•Replace the sensor
•Clean the sensor
•Proceed to calibration
of the ORP sensor (see
process page 13)
•Replace the ORP sensor
