Question: Are there any reference plaques available to verify that the iCPlate2I is reading correctly?
Answer: Yes. The iCPlate2 Target is a long-term stable absolute reference. You can use the iCPlate2 Target to test the device for its exactness, and if necessary to calibrate it. The reference plate used by X-Rite is an extremely precise cut glass substrate that is metal vaporized and, as is usual in semi-conductor manufacturing, etched out. It is embedded in gray plastic. The reference plate has a lifetime of two years. The expiration date and the serial number are printed on the label.
