7.1 Predictive pH Sensor

Diagnostics

End-of-Sensor Life

☞

The analyzer can predict the date (month/year) for the end
of the pH sensor’s operating life. This predictive diagnostic
feature operates automatically and continuously. You need
not enable or configure this feature.

The analyzer forecasts the predictive diagnostic end-of-
sensor life date based on information contained in the
“Calibration Record.” The analyzer monitors the degrada-
tion of the sensor’s slope, offset, electrode impedance, and
other parameters over time.

NOTE:

The  “Calibration Record” is only updated during a
calibration. Consequently, for the predictive diag-
nostics to be useful and important the sensor must
be routinely cleaned, maintained, and calibrated.
Failure to do this may prematurely update the end-
of-sensor life date, providing a false indication to
replace the sensor, when all it may really need is
cleaning and/or routine maintenance. (See sensor
operating manual for cleaning and maintenance
information.)

You can scroll to the “PREDICT: month/year” date (shown
on bottom line of MEASURE screen) using

. Un-

til a “first-time” sensor calibration is performed, the display
indicates  “PREDICT: 0/00.” After the first calibration, the
display indicates the month in which calibration was per-
formed, and the five-year maximum prediction. As more
calibrations are performed, the end-of-sensor life date is
updated based on the rate of degrading sensor perform-
ance (active or glass electrode impedance, slope, and
offset). Example: Suppose a new sensor is installed and
calibrated every month based on process conditions. When
originally installed, the sensor had a slope of 60 mV/pH.
After the first and two subsequent monthly calibrations, the
analyzer diagnosed that the sensor slope is degrading at a
rate of 2 mV/pH per month. Based on this rate, the analyzer
predicts the date that the sensor will no longer be useable.
When the “predict” date actually occurs, the analyzer dis-
plays a “WARN” alert, and creates diagnostic message # 34
(predicted probe date) which can be displayed by accessing
the “Messages” submenu in the DIAGNOSTICS menu.
