Required Software Version
- Calman Version 5.12.3 or newer
- No external drivers are needed; the meter is configured as a Windows HID device.
Important: Calman does not require the installation of any additional software. First and Third-party software that captures the meter can prevent other software from connecting to the meter. If you have installed the other applications that connect to the meter, you may need to uninstall it before connecting Calman to the ColorChecker Display Plus.
The ColorChecker Display Plus includes an attached white disk diffuser for use when taking ambient light measurements or measuring direct light sources such as a projector in direct view mode. In all other modes, the diffuser is not used. The diffuser pops slightly away from the meter body and swings away from the lens.
Flat Panels and Rear-Projectors
The ColorChecker Display Plus should be positioned with the face of the meter squarely in contact with the center of a flat panel or rear projector screen, to block ambient light. The cable counterweight can be draped over the top of the display to facilitate this.
The ColorChecker Display Plus has a tripod mount for use in non-contact mode, to measure front projector screens. The ColorChecker Display Plus should be placed about three feet (1 meter) back from the screen.
Calman Connection Procedure

- On the Meter Settings page, click Find Meter.

Low Light Handler
When enabled, the low light handler averages multiple meter samples per measurement, when measuring light levels below the specified Low Light Trigger level.
Note: For better low light accuracy on many consumer TVs, the following Low Light Handler options are recommended:
- Low Light Handler: Enabled
- Low Light Mode: 4 or 5 Seconds
- Low Light Trigger: 1 cd/m2
