In the “Span Input X/Range Y” section, enter the span voltage that you are sourcing in and click on the
Calibrate button. A suggested value will be supplied. This will calibrate the span range. The progress of the
calibration will be shown in the progress bar at the bottom of the screen. Repeat these steps for all of the
inputs.
Clicking on the Next -> button will display the next screen(s) for the user calibration. Clicking on the
<- Back button will display the previous screen(s).
To calibrate the zero range for the
outputs, you must first attach your
measuring device.
In the “Zero Output X” section, click on the
Prep for Zero button. Let the unit output
what it has set for the zero measurement,
then enter what you are measuring coming
out of the terminals. Once entered, click on
the Calibrate button and let the procedure
finish. The progress of the calibration will
be shown in the progress bar at the bottom
of the screen.
In the “Span Output X” section, click on the Prep for Span button. Let the unit output what it has set for the
span measurement, then enter what you are measuring coming out of the terminals. Once entered, click on
the Calibrate button and let the procedure finish. The progress of the calibration will be shown in the
progress bar at the bottom of the screen. Repeat these steps for all of the outputs.
Once all of the inputs and outputs have been calibrated, return to the first screen for cold junction
calibration, if necessary.
Step 2. Cold Junction Calibration.
If you have recently finished the zero and span calibration, and the calibration screen is still displayed,
select “Done” and return to the user display. Set up the calibrator for the specific thermocouple type of the
thermocouples in the analog board: type K, type J, etc. Then source a specific temperature, like 1000°F. It is
recommended that the actual temperature used be similar to an appropriate process temperature. For
example, if your equipment normally operates at 1700°F, then perform the cold junction calibration using a
1700°F signal. Compare what you source (on meter) to what the actual reading is (shown in Configurator). If
the values are out of tolerance (per your specifications), then refer back to the User Calibration section.
The user can enter the cold junction offset in the box next to the Calibrate button. The current cold junction
value will be displayed next to
the “Current CJ Value:” line.
To determine whether a cold
junction adjustment is
necessary, source a specific
temperature to the input (as
explained above). If the
temperature reading
displayed is not sufficiently
close to the source value,
then the “Offset” will need to
be changed. Enter the
amount of change in the
“Temperature of Terminals”
