Click on the Calibrate button to begin the calibration.
A progress bar will be displayed along the bottom of the screen giving the progress of the calibration.
Zero Calibration - Outputs
To perform a zero calibration, click on the “Zero”
option - The circle will be filled in with a dot for the
selected option. When ready to start the calibration,
click on the Ready button. The user will then have to
measure the current at the appropriate output
terminals and enter that value on the button next to
the Ready button by clicking on that value button and
entering the value.
Click on the Calibrate button to begin the calibration.
A progress bar will be displayed along the bottom of
the screen giving the progress of the calibration.
Span Calibration - Outputs
To perform a span calibration, click on the “Span” option - The circle will be filled in with a dot for the
selected option. When ready to start the calibration, click on the Ready button. The user will then have to
measure the current at the appropriate output terminals and enter that value on the button next to the
Ready button by clicking on that value button and entering the value.
Click on the Calibrate button to begin the calibration.
A progress bar will be displayed along the bottom of the screen giving the progress of the calibration.
Cold Junction Calibration
The “Cold Junction” option will allow the user to
perform a cold junction trim on the selected
board.
To determine if a cold junction adjustment is
needed, hook up the calibrator with the
appropriate T/C wire attached, and source a
temperature to the input. It is recommended to
use an operating temperature to source. For
example, if the furnace typically runs at 1700 °F,
then 1700 °F should be sourced to the input. If
the displayed value does not equal the value
being sourced, then a cold junction adjust would
be necessary. The “Offset” will be the amount
of change desired. For example, if 1700°F is
being sourced, and the “Value” is showing
1696.4 °F, then the “Offset” would be set to 3.6. If 1700 °F is being sourced, and the “Value” is showing
1702.3 °F, then the “Offset” would be set to -2.3.
Click on the Calibrate button to begin the calibration.
Wait 120 seconds and verify with a source calibration device with the correct T/C type.
Note: During a
normal calibration procedure, the user should zero and span all of the inputs first and then perform a cold
junction calibration, if necessary
.
It is recommended after each Cold Junction calibration to source a value in and check what the displayed
temperature reading is.
