- Page 7 Your instrument was packaged in a specially designed carton to assure against damage. If reshipment is necessary, the instrument should be packaged in the original carton. If the original carton is not available, contact X-Rite at: 1-888-826-3044 or 1-616-803-2100 to have a replacement shipped to you.
- Page 8 Instrument Description The 396 Sensitometer is a battery operated, dual color, single sided exposure sensitometer, designed for quality control of cine and X-ray processing systems. It produces a repeatable stepped exposure on applicable film. Its ease of operation enables anyone with little instruction to expose repeatable sensitomerty strips, with either blue or green exposing light—simulating the light from blue and green intensifying screens.
- Page 9 Refer to Section Four to see battery replacement procedure. If this does not rectify the problem, refer the instrument to X-Rite or an authorized service center for proper servicing. There are no user serviceable components in the sensitometer.
- Page 10 2. Application and Procedures Sensitometer Monitoring For Process Control The sensitometer exposes film with a known quantity of light through a 21-step light modulator. The maximum light is emitted from Step No. 21. Each successive step emits approximately 70.7% of the light emitted from the step adjacent to it (.15 log exposure).
- Page 11 • Density Difference (Contrast Index): This is a calculation of the slope in the straight-line portion of the D-Log E Curve. Choose the High Density (HD) step as the step closest to 2.20D. The Low Density (LD) step is chosen as the step closest to but not lower than 0.45D.
- Page 12 Use sensitometry whenever trouble is suspected, or a change has been made to the process. Processing Procedure Allow the processor temperature and X-Rite chemistry to reach equilibrium when starting up the processor before processing film. Films should be processed immediately after being exposed.
- Page 13 After processing of film is complete, record the date, time, and processor identification number on the film in the designated areas. Manual Data Recording Procedure Establishing Normal Mid Density, Density Difference, and Base+Fog The normal mid density (speed index), density difference (contrast index), and base+fog values are established on a representative film, when the processor is considered to be operating in an optimum fashion.

- Page 15 Automatic Data Recording Procedure Using the 391 Densitometer When the X-Rite 391 densitometer is used to measure process control films, it will automatically calculate and store the values for: mid density (speed index), density difference (contrast index), and base+fog. The unit will also store up to 32 measurements of film data for twelve processors.
- Page 16 Processor Troubleshooting When troubleshooting out of tolerance processor conditions, use Mid Density (Speed Index) as the primary guide. This is the most predictable indicator for all film types. Base+Fog is predictable, but is the least sensitive. Density Difference (Contrast Index) reacts predictably for a given set of film conditions but may vary from film to film.
- Page 17 3. Using the Sensitometer Setting Exposure Color Optimum sensitometric control occurs when the proper color light exposes the film. Expose with the same color emitted from the intensifying screen recommended by the film manufacturer for the film being exposed. For example, when using blue emitting intensifying screen—expose in “BLUE”...
- Page 18 1.OD+ Base+Fog on Step No. 11. • If the X-Rite 390 or 391 Densitometer is used to measure film strips, the sensitometric exposure must meet the following criteria:...
- Page 19 - The exposure must have a gamma of .7 or greater on steps 7 through 15. (increasing density increments of at least .11D). - The film must have at least 1.25 inch of clear leader at both ends of the exposure. The use of 8" x 10"...
- Page 20 Allow cover to raise and remove the film immediately. Develop the film in the processor to be monitored (refer to Section 2). Record data on film immediately after development (refer to Section 2).
- Page 21 Because of the complexity of the circuitry, all repairs should be referred to the factory. X-Rite will repair any 396 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.
- Page 22 Cleaning the Instrument Your instrument requires very little maintenance to achieve years of reliable operation. The following cleaning procedures should be performed from time to time. General Cleaning The exterior of the instrument may be wiped clean with a cloth dampened in water or a mild cleaner, whenever required.
- Page 23 Replacing the Battery A low battery condition prevents exposures from occurring. Always Replace The Battery before referring the unit for service. Turn Power Switch “Off” and remove battery access cover. Disconnect old 9-Volt battery from the circuit and discard appropriately. Connect a new 9 Volt Alkaline battery to the circuit—recognizing proper polarity—and insert into the compartment.
