Repair Information
Your 393/394 Instruments are covered by a one-year limited warranty—excluding alkaline battery—and should be referred to the factory for repair within the warranty period. Attempts to make repairs within this time frame may void the warranty.
X-Rite provides a factory repair service to their customers. Because of the complexity of the circuitry, all repairs should be referred to the factory.
X-Rite will repair any 393/394 past warranty. The customer shall pay shipping cost to the factory, and the instrument shall be submitted in the original carton, as a complete, unaltered unit.
Calibration/Recertification
X-Rite sensitometers are calibrated at exposure setting “3” at the factory. The exposure of Step 11 is adjusted to match factory standard instruments maintained by X- Rite.
A certificate of calibration is provided with each instrument, along with a calibration sticker that is initialed and dated by the Quality Assurance Inspector. Because calibration requires a master instrument for comparison, sensitometers do not have user accessible calibration adjustments. X-Rite offers a recertification program to verify sensitometer calibration. Recertification is recommended every 12 months and can be arranged through X-Rite’s Customer Service Department.
