Calibrate Aux Analog Input

If an SSi analog input board is set up, then this menu option will be visible. The Calibration menu screen
will allow the user to calibration the zero, span, and cold junction trim value for all of the inputs on each

board.
The Select button at the top of the screen will allow
the user to select one of the current boards to
perform a calibration on.
Select the appropriate board and click on the OK
button. Clicking on the Cancel button will not select
the board to calibrate.

Note: A board must be

selected for calibration to begin

.

The user will need a thermocouple calibrator capable of outputting a thermocouple signal to calibrate the
zero, span or cold junction value of the input board. The user will need to connect the calibrator to one of
the inputs on the analog board for the channel that will be calibrated. It is recommended to let everything
(calibrator and analog board) sit for approximately thirty minutes to allow the temperature to achieve
equilibrium. It is important to note that when performing a zero or span calibration,

do not use

regular

thermocouple wiring. Instead, use any kind of regular sensor wire, or even regular copper wire. To
perform the calibrations, the user will need a calibrator that is capable of outputting volts, millivolts, and
temperature.
The “Zero/Span” tab will allow the user to perform a zero and span calibration on the selected board.

The help button -

- next to the “Range” drop-down list will allow the user to select a range based upon

an input type if the range is not known.

Select the input type and click on the OK button. The correct millivolt range will be displayed in the drop-
down list. Click on the Cancel button to cancel this action.

Below is a listing of the suggested ranges for the various TC types.
