UNPACKING
Remove the instrument from shipping carton. Inspect for possible damage. If any damage is noted, contact the transportation company immediately. Do nothing more until the carrier’s agent has inspected the damage.
If damage is not evident, make sure the following items are included.

• X-Rite 301 Operation Manual (with Warranty Card)
• 1mm, 2mm and 3mm apertures (inside back cover of manual)
• Standard Reference Step Tablet (inside front cover of manual)
• 301(X) Instrument

OPERATING INSTRUCTIONS

Operation of the X-Rite 301 is very simple. Procedures of the various modes of operation are provided in the following paragraphs. When operating the instrument, use these recommended common sense suggestions to protect yourself and your instrument:

• Avoid dangerous environments (e.g., don’t use instrument in damp, wet areas)
• Use proper electrical connections.
• Ensure electric cord does not interfere with work.
• Disconnect power before servicing.

POWER APPLICATION
The 301(X) is designed to operate from a standard grounded line source.
Always plug the instrument into a 3-wire receptacle.

1. Plug line cord into a 3-wire grounded outlet.
2. Turn on power switch.

APERTURE REPLACEMENT
Remove the installed aperture by lifting the edge upward. Install a new or different aperture by inserting the aperture into the light source cavity, making sure that the aperture is fully seated and pressed flush against the cavity. NULLING (ZEROING) PROCEDURE
Due to the electronic memory loss caused by power removal, null must be established each time power to the instrument is removed. Null remains very stable (±0.01D) as long as power remains on.
Null the instrument as follows:

1. Remove film from reading area.
2. Lower the reading head by pressing the read button until it deflects totally and actuates the switch.
3. Momentarily push the null button.
4. Remove pressure on the read button to release the reading head.

NOTE: The read button is a read-hold activator. Compress the button with only as much pressure as necessary for total deflection.

ABSOLUTE DENSITY MEASUREMENT
Measure absolute density as follows:

1. Null the instrument as previously described in Nulling (Zeroing) Procedure.
2. Center the film area directly over the bright green light spot under the reading head.
3. Lower the reading head by pressing the read button until it totally deflects and actuates the switch.
4. Allow the instrument reading to settle to a stable number.
5. Remove pressure on the read button to release the reading head.

NOTE: Always measure density with the film emulsion side up. When measuring density values above 2.50D, ensure that reading head light seal is completely on surface of the film being measured.

DENSITY COMPARISON MEASUREMENT
Compare density readings as follows:

1. Place reference film over aperture. Press read button and momentarily press the null button.
2. Place the film to be compared over the aperture and measure density.
   • This measurement is the difference between the reference film density and the compared film density.
   • A negative (–) display indicates a lower compared film density than the reference film.

NOTE: When referencing with densities greater than 3.00D, press the null button longer to allow the instrument electronics to fully stabilize.

CALIBRATION

Calibration of this instrument should remain stable over a long period of time and over an extended range of voltage and temperature. However, a calibrated step tablet is provided (inside front cover) to verify the instrument calibration. Handle the step tablet with care to prevent accumulation of dirt and fingerprints on the surface.

CALIBRATION FREQUENCY
Under normal operating conditions, the instrument calibration should be verified once a week by the following the Calibration Procedure.

CALIBRATION PROCEDURE
See illustrations on the following page for calibration adjustment locations and reference.

To verify calibration:

1. Null the instrument as described in Nulling (Zeroing) Procedure page
2. Center the “CAL” portion of step tablet under read head.
3. Press read button to measure step tablet.
4. Hold read button down until a stable reading is attained.
   • The “CAL” reading should be ±0.02D of the “CAL” value marked on the step tablet.

If “CAL” reading is NOT within tolerance, calibrate instrument.
To calibrate instrument:

1. Center the “CAL” portion of step tablet under the read head.

2. Press and hold read button to measure the step tablet.

3. Use a small screwdriver or adjustment tool into hole on the right side of instrument, to engage the calibration adjustment (potentiometer).

4. With read button still depressed, adjust as necessary to within ±0.02D of the “CAL” value marked on the calibrated step tablet.
   • Rotate counterclockwise to increase value, clockwise to decrease.

5. Remove step tablet and press read button to check null, re-null the instrument as necessary.

6. Repeat until the calibration value and null are within tolerance.

NOTE: Always return the step tablet to the plastic bag on inside front cover for protection.

OUTPUT CONNECTION (301RS)

The Model 301RS has the capability of sending measurement data to a printer, computer, or modem. This is done through the use of a RS- 232 output connection located in the rear of the instrument. Data is sent each time the READ button is released.
RS-232 CONNECTION
Use a RS-232S type cable to connect the 301RS and the receiving device. The Transmit Function Switch, located inside the instrument, must be set to DTE (Data Terminal Equipment) or DCE (Data Communication Equipment) to correspond with the receiving device. The DTE setting sends the TRANSMIT signal through pin 2 and is normally used for printers or computers outputs. The DCE setting sends the TRANSMIT signal through pin 3 and is normally used for modem outputs.
NOTE: The output connection is preset from factory to DTE operation for X-Rite 301 units and DCE operation for Fuji 301 units.
To change the Transmit Function Switch setting:

1. Disconnect power to instrument.
2. Turn unit upside down and remove bottom cover by the four screws in located in the rubber feet.
3. Set the Transmit Function Switch to DTE for printer or computer connections or DCE for modem connections.
4. Return bottom cover in place and secure with four screws.

DATA INSTRUCTION FORMAT
Data is sent in the following format:
