6.1 Controller Calibration (Adjustment)
The M330 has a precision, thermocouple
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
THERMOCOUPLE’s. 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
THERMOCOUPLE input measures the value
shown in INPUT #, force the display to show
the value in the corresponding OUTPUT #
and do linear interpolation between points”.
Follow directions below to alter output
values from the controller front panel.
Note: You may download Eurotherm iTools Software from this web site:
http://www.eurotherm.com/itools/itdnlds.htm
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.
To gain access to the custom look-up table, refer to the 4 square buttons on the face of the
controller and use this procedure.
1. Press 1 until ACCESS appears. If Access Level and Level 1 appear, skip to step 3.
