Calibration Features
The PCR II Plus calibrates itself to ensure that its CRT brightness and
contrast levels remain consistent throughout the day.
The film recorder calibrates:
• At the end of the warm-up sequence.
• Each time you remove and replace the camera back.
• Each time you select a new film type.
The PCR II Plus also calibrates periodically during routine imaging un-
less you select the DISABLE CAL function to disable the automatic cal-
ibration.
Calibration Functions
There are three calibration functions:
1. CRT CALIBRATION forces the PCR II Plus to calibrate all of its as-
signed brightness and contrast levels. Use this function to clear a
brightness or contrast calibration error message.
2.
DISABLE
CAL
shuts
off the PCR II
Plus
calibration
routine.
The
film
recorder will not calibrate even when a command to force a cali-
bration is sent from the host computer.
Note: In normal operations, leave calibration on.
However, there may be certain imaging applica-
tions where it may be easier to work with calibra-
tion shut off.
3. ENABLE CAL turns on the calibration routine if you had previously
disabled it.
