Calibration procedures
a. Once the value has stabilized, the Buffer Solution Value field will
automatically populate to match the exact buffer value. You may
also change the value, if desired. Touch
Calibrate
.
b. Touch
Done
in the lower right corner of the screen to return to
the pH Settings screen.
5. Follow the steps below for 2-point calibration.
Note:
Three-point
calibration uses the same steps, but will repeat steps “d” and “e”
for the third calibration point.
a. After touching
2-Point Calibration
, a screen will appear
prompting you to select a temperature compensation to use for
the calibration. The expected buffer temperature will be used if
there is no RTD present. You can also use the RTD, if present,
by setting the slider to enable it. Touch
Next
.
b. The screen that appears will prompt you to put the pH sensor
(and RTD, if selected) into the first buffer solution for Calibration
Point 1. Touch
Next
.
c. The following screen displays the stabilizing pH sensor value for
Calibration Point 1. Once the value has stabilized, the pH value
field will automatically populate to match the exact buffer value.
You may also change the value, if desired. Touch
Calibrate
.
d. The screen that appears will prompt you to put the pH sensor
(and RTD, if selected) into the second buffer solution for
Calibration Point 2. Touch
Next
.
e. The following screen displays the stabilizing pH sensor value for
Calibration Point 2. Once the value has stabilized, the pH value
field will automatically populate to match the exact buffer value.
You may also change the value, if desired. Touch
Calibrate
.
f. The following screen states that the pH calibration is done, and
prompts you to update the desired temperature compensation
in the next screen. Touch
Next
.
g. Set the temperature compensation to use when the sensor is
set as active. The expected buffer temperature will be used if
there is no RTD present. You can also use the RTD, if present,
by setting the slider to enable it. Touch
Done
.
h. The pH Calibration Complete screen should appear. Touch
Done
in the lower right corner of the screen to return to the pH
Settings screen.
