8.
Press
to read the sensor input value of Pt 1.
Note that the Raw Input Measurement has been automatically entered into
the Pt 1 Sensor Input Value field, and the standard value is now displayed as
the Calibrated Output Measurement.
9.
Place the probe in the second known standard.
10. Enter the value of the standard in the Standard Value field for Pt 2.
11. Observe the Raw Input Measurement displayed near the bottom right corner
of the screen and wait until it has stabilized.
12. Press
to read the sensor input value of Pt 2.
Note that the Raw Input Measurement has been automatically entered into
the Pt 2 Sensor Input Value field, and the standard value is now displayed as
the Calibrated Output Measurement.
13. Press
to accept the new calibration and return to the Sensors screen, or
press
to cancel the new calibration and revert to the previous or default
calibration.
One-Point Slope Calibration Procedure
A one-point slope calibration requires one known standard. For instance, if you
are calibrating a dissolved oxygen sensor, you might use 100% saturated water,
for which you can look up the oxygen concentration based on temperature and
pressure.
The fields of the Calibration dialog box are identified on page 74.
1.
From the Sensor field, select the desired sensor.
2.
From the Measurement field, select the desired measurement.
3.
Set the Single/All field to “Calibrate selected measurement only.”
4.
From the Calibration Type menu, select 1 Point Slope, if it is not already
selected.
5.
Place the probe in the known standard.
