3.2.6 Controller Calibration

This blackbody has a precision temperature
sensor monitoring the emitter temperature. The
THERMOCOUPLE measurements are passed
through a look-up table that ultimately
provides the correct exit radiance temperature

for the indicated temperature. A separate
calibration report is included.
This controller has been programmed to contain
a custom look-up table that may be used to
precisely calibrate the controller/indicator
against reference sensor. The look-up table to

the right appears as shown in the controller GUI
interface (not supplied).
The logic of this table is: “when the sensor input
measures the value shown in INPUT #, force the
display to show the value in the corresponding

OUTPUT # and do linear interpolation between
points”. A sample table is shown to the right.
The actual table used for your calibration is
shown on the next page.
Follow directions on the next page to alter
output values from the controller front panel.

Note: You may download Eurotherm iTools Software from this web site:

http://www.eurotherm.com/products/controllers/itools/

With this software and some practice, you will see this GUI interface screen. To permit

iTools to talk to your blackbody, you may have to set the controller comm. port to
“Modbus” mode. Procedure to change communications to Modbus are shown in
Section 3.2.7.
