Sensor
Calibration
All analog sensors can be calibrated
directly based on a wet test, or using a
2-point method. You can reset the
input to factory default calibration as
well.
1- Press
the
CAL
button.
2- Use the Up and Down arrows to
locate the sensor you wish to
calibrate and press
OK
.
Notice the underline in the current
value on the next screen. That is the
cursor. In this single point calibration
screen, the up and down arrows will
adjust this digit. The right and left
arrows will move the cursor to a
different decimal digit to match your
wet test. Pressing
F1
SAVE completes
the single point calibration adjustment,
-or- Pressing
F3
MORE gives you
more calibration options.
The calibration program allows you to
select a single or 2-point calibration
method. Once chosen, the screen that
follows step 2 above will be that
choice. From this screen, you can select
F3
, MORE,
to switch back to the other mode or select reset to
factory calibration.
3a- (Single Point Calibration) Edit the value and
press
F1
to SAVE. Choose
F1
again to calibrate
another sensor or press
ESC
to exit.
OR
3b- (2-Point Calibration) Place the sensor into a
known value sample or pH buffer (i.e. 7.00 pH
buffer). Adjust the reading until it is equal to the wet
test or buffer. Press
F1
to
continue to the
NEXT
buffer.
4- Place the sensor in the second buffer (10.00
pH)or known sample and edit as before.
Press
F1

CAUTION!
Correct sensor operation / Run-in period
Accurate measuring and metering is only
possible if the sensor is working correctly.
Please read the operating manual for the
sensor for more information.
Please also read the operating manuals for
the fittings and other components used.
It is imperative that the run in periods of the
sensors are adhered to.
The run in periods should be allowed for
when planning commissioning.
It may take an entire 24 Hour day to run in a
new CTE or CGE sensor.
