TC Extension Correction Curves

 

 

This menu option will allow the user to set up to three TC correction curves for the 9220 controller.  The error offsets applied here will only affect the corresponding temperature value. Once the curve has been completed, it can be applied to an input by using the SSi Analog Input Setup option in Configurator.  Clicking on the “click” value for a curve will display the curve edit form.  Note: If the first “Temperature” value and the first “Error” value are both zero, then the curve will not be set.  The user can enter up to ten “Temperature”/“Error” combinations.  The range for the “Temperature” field is –300 to 9999.  The range for the “Error” field is –30.000 to 30.000.

 

NOTE: Curves are interpolated between points in order to provide a smooth transition between those points.  For example:

 

Point	Temp	Error
1	100	0
2	300	2

 

In the above setup, temperatures would read as follows:

 

Actual Temperature	Displayed Temperature
100	100
150	150.5
200	201
250	251.5
300	302
