GammaCompMD QA Client User Manual

A LCD display is fragile and may be damaged if the external sensor

is forcefully pressed against it. Never attach a sensor with suction

cups to the display. Always use the supplied cable and suspend the

sensor with a weight so that the sensor is stationary in front of the

display.

If the external sensor is separated from the screen during

calibrations or tests (i.e. by falling off), the process may fail. Be

sure to keep the external sensor in place, until the process is

completed. If the sensor has been displaced, position the sensor

on the screen again and best restart the process.

Black Level setup Several supported external sensor models require the adjustment

of the Black Level (Dark Current) for improved accuracy. This Black

Level measurement will be performed before any calibrations and

tests. Please follow the guidance on the screen. In most cases, the

sensor needs to be placed on a dark surface for this setup.
