Calman supports the X-Rite i1 Display colorimeter (Retail and OEM) for measuring many display types, including CCFL, LED, plasma, and also front and rear projectors.
Required Software Version
- Calman version 4.5 or newer
- No external drivers needed; the meter is configured as a Windows HID device.
Important: Calman does not require the installation of any X-Rite software The X-Rite i1Profiler software captures the meter (X-Rite services) and prevents other software from connecting to the meter. If you have installed the i1Profiler software, you will need to uninstall it before connecting Calman to the i1Display.
Meter Diffuser
The i1Display 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.
Meter Positioning
Flat Panels and Rear-Projectors
The i1Display 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.
Front Projectors
The i1Display has a tripod mount for use in non-contact mode, to measure front projector screens. The i1Display should be placed about three feet (1 meter) back from the screen.
