9.6 Using the Calibration Wizard with Running
Programs
The RTDAQ Calibration Wizard provides an easy to use interface which
steps the user through the calibration process described above. By using
simple screens to gather information, the proper changes to the mode variable
and known measurements are performed automatically by the Wizard. The
user only needs to set the sensors to the known value(s), and provide a few
required inputs to the Wizard. This greatly simplifies the user’s interaction
with the sensors and datalogger program.
9.6.1 Calibration Wizard Basic Operation
When a program with one or more FieldCal instructions is running on a
datalogger, and RTDAQ is connected to that datalogger, you can select
Datalogger | Calibration Wizard from the RTDAQ menu to start the Wizard.
A list of measurements referenced from one or more FieldCal instructions used
within the program is then displayed to the user. The user selects a
measurement for calibration and moves forward by entering known values, if
necessary, and triggering calibration steps.
9.6.2 Using the Wizard to Perform Two-Point Multiplier and
Offset Calibrations
To perform a two-point calibration using the Wizard, run a program in your
datalogger utilizing a two-point multiplier/offset in the FieldCal instruction.
Connect to your datalogger and choose Calibration Wizard from the
Datalogger menu.
The steps for performing a two-point slope only (multiplier only)
calibration in the Wizard are nearly identical to those for a two-
point multiplier and offset calibration. Only a two-point
multiplier and offset calibration example will be shown here. NOTE
