2. Press 2.
3. Press 4 until Level 3 appears.
4. Press 4 until 3 appears. Wait.
5. Press 1 until INPUT OPERS and Cust Lin 1 Page appears.
6. Press 2 until display shows the Output # that corresponds to the calibration point shown
in the listing on the previous page.
7. Use the UP/DWN buttons (3 and 4) to dial in the measured radiance temperature from a
freezing point transfer device or other radiance standard.
8. Press 2 to view/change more correction points.
9. Press the round center button located above 2 and 3 to resume normal display until
ready to lock controller.
10. When finished with all calibrations and to lock the controller, press 1 until ACCESS
appears.
11. Press 2.
12. Press 3 until Level 1 appears.
13. Press the round center button located above 2 and 3.
Note: Calibration points do not have to be used as pre-programmed. To dial in a
different calibration point, simply change an INPUT # and the corresponding OUTPUT #
to be the new desired calibration point. Set the blackbody to the calibration
temperature using its setpoint. When exit radiance data is measured, dial in the new
OUTPUT # temperature as described above. All cal points must be in ascending order!
Example: In place of Silver freezing point correction at 961.78 °C, you prefer to use 1000 °C.
1. Using the above steps, set INPUT 9 equal to 1000.0. Set OUTPUT 9 equal to 1000.0.
2. Allow blackbody to control and stabilize at 1000.0 °C.
3. With your radiance standard, you measure 1001.2 °C.
4. Use the above procedure to dial in 1001.2 in the OUTPUT 9 location.
5. Wait for blackbody to re-stabilize at 1000.0 and verify radiance temperature.
All corrections between calibration points are performed using straight-line interpolation.
6.2 Tune Controller at Setpoints
When temperature is somewhat stable at 300 °C, activate AUTOTUNE by:
1. Press 1 until ACCESS appears.
2. Press 2.
3. Press 4 until Level 3 appears. Wait.
4. Press 4 until 3 appears. Wait.
5. Press 1 until AUTOTUNE appears.
6. Press 2 until display shows the word off.
7. Press 4. Display will show ON. Unit will go into autotune mode.
8. Press center round button.
9. When finished, all displays will appear normal (no ‘tune’) anywhere on display.
Repeat the above steps 1-8 for the following setpoint temperatures: 550 °C, 750 °C, and 1400 °C.
