Zero Calibration
To perform a zero calibration, click on the “Zero” option - The circle will be filled in with a dot for the
selected option. The millivolt range for the input will need to be set so that the span values are correct.
The chart below will determine the range for each T/C type.

For a zero calibration, the recommended value to source
is 0 mV. The user can also individually select each input
(one through three/five) to calibrate, where Check = yes
(calibrate) and No Check = no (do not calibrate).
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
To perform a span calibration, click on the “Span” option - The circle will be filled in with a dot for the
selected option. The millivolt range for the input will need to be set so that the span values are correct.
When a range is selected, the recommended value will also be populated. For a span calibration, the
recommended value is 90 % of the full range. For example, if the range is 80 mV, then the span should be
72 mV. The recommended value can be changed by clicking on the recommended value and entering the
new value. The user can also individually select each input (one through three/five) to calibrate, where
Check = yes (calibrate) and No Check = no (do not calibrate). Once an input is checked, its current value will
be displayed.
For a span calibration, a value of 90 % of the full range
(or the adjusted value) will need to be sourced to the
input or inputs.
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.
The user can select the input to perform the trim on
from the “Input” box. The user can enter the cold
junction offset in the “Offset” box. The current
temperature value will be displayed next to the “Value:”
line.
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
