WHEN TO CALIBRATE SENSOR
Calibration is required:
After an extreme change in temperature (+/– 30°F or +/–15°C) from the current calibration map.
After an extreme change in exposure time (+/– 1/2 sec) from the current calibration map.
If either the T or E in the CAL: T/E indicator is not green.
If the noise profile shows patterns or lines. For more information, go to
“Check Noise Profile” on page 109
.
After each firmware upgrade.
To check the temperature/exposure of the current calibration file, go to

CALIBRATE SENSOR: MANUAL CAPTURE
The camera offers two (2) ways to calibrate the sensor: Manual Capture and Auto Capture. This section
describes how to calibrate the sensor with Manual Capture. For more information on Auto Capture, go to
“Calibrate Sensor: Auto Capture” on page 111
When you start a Manual Capture, the camera calibrates the sensor at the current exposure and temperature
setting. You will need to re-calibrate the sensor after extreme changes in exposure and temperature. The
Manual Capture process takes several minutes.
To perform a Manual Capture, follow the instructions below:
1. Ensure that the camera reaches the temperature you want to use for your shoot.
2. Set the exposure to the exposure you want to use for your shoot.
3. Ensure that the sensor is as dark as possible.
‒
Preferably, take off the lens, and install the front body cap.
‒
If you cannot take off the lens, put a lens cap on the lens. (Not all lens caps completely block IR. Lens
caps are made to protect the lens, not necessarily to block light.)
‒
If possible, use a dark room.
‒
Just closing the aperture is NOT sufficient.

NOTE:
If the calibration map name is “empty”, that means that the only calibration map on your camera is
the factory calibration.
5. You can create up to four (4) calibration maps at a time. Select a check box for each calibration map you
want and select the exposure you want for each from the drop-down menus.
6. Select
Start Capture
.
A dialog box displays, reminding you to cover the sensor.
7. Select
OK
to continue.
The system initializes and then makes multiple passes through the following phases of the calibration:
‒
Capturing
‒
Analyzing
‒
Erasing
‒
Programming
8. When the Calibration Successful dialog displays, select
OK
to complete black shading.
The new calibration map is automatically selected.
