TEMP CHANGE
Temperature Change sets the increment (in degrees) of change required to automatically trigger the FFC process when the temperature changes in the field of view. After each FFC, the camera resets the baseline temperature and resumes temperature monitoring.
You can select from the following:
•1.0 - 3.0°C
•1.8 - 5.4°F
The default is based on the Temp Units settings (refer to Temp Units on page 48):
•1.0°C
•1.8°F
To program the temperature change:
1.Program preset 95 (28). The main menu appears.
2.Position the cursor (>) beside <Camera>. Press the Iris Open button; the menu appears.
3.Position the cursor (>) beside <Flat Field Correction>. Press the Iris Open button; the menu appears.
4.Position the cursor (>) beside Temp Change. Press the Iris Open button; the cursor moves to the right.
5.Move the joystick up or down until the desired Temp Change setting appears.
6.Do one of the following:
•Select: Press the Iris Open button to select the option.
•Cancel: Press the Iris Close button to leave the setting as is.
DO MANUAL FFC
From time to time, image quality may degrade. When this happens, perform a manual FFC. After manually performing this process, the camera restarts the frequency clock and resets the baseline temperature.
To manually perform the FFC:
1.Program preset 95 (28). The main menu appears.
2.Position the cursor (>) beside <Camera>. Press the Iris Open button; the menu appears.
3.Position the cursor (>) beside <Flat Field Correction>. Press the Iris Open button; the menu appears.
4.Position the cursor (>) beside Do Manual FFC.
5.Press the Iris Open button to perform the FFC process. The cursor briefly changes to an asterisk (*) during the FFC process. You can also call preset 89 to perform the FFC quickly.
