    S E C T I O N O N E PRODUCT DESCRIPTION The X-Rite 891/892 automated instruments measures paper, film, and printer balance control strips. Simply insert the strip into the instrument for motorized, automatic measurements. Red, green, and blue density data is sorted for fields such as HD, LD, and Stain, then simultaneously displayed and transmitted to a minilab printer for analysis.

  • Page 15: Applying Power

    To apply power to the instrument: 1. Verify that the voltage indicated on the adapter complies with the AC line voltage in your area. If not, contact X-Rite or your authorized representative. 2. Insert the small plug from the adapter into the power-input connector on the instrument.
