X-Rite 310 Operator Manual INTRODUCING THE X-RITE 310 When we designed the 310, we took a close look at the needs of the photofinishing industry. Then, we applied years of experience in densitometry to develop this sophisticated color transmission/reflection densitometer.
X-Rite, Incorporated, use the original carton. If the original carton is not available, X-Rite can ship a replacement to you. A padded carrying case for your 310 is available from X-Rite. It provides the safest possible storage for your instrument, and also makes it easily portable.
Aperture Keyboard The 310 Transmission Densitometer The 310 Transmission Densitometer provides a Light Table platform for backlighting transmissive measurement targets such as film and transparencies. The Reading Head Arm that extends over the Light Table features the Keyboard and the Reading Head.
You can select an aperture (measuring area) of 1mm, 2mm, or 3mm. All three sizes are supplied with your 310. If you are unsure which size is best for your application, use the 3mm aperture; it provides the best results for averaging film measurements.

Then, a vocabulary overview of the instrument keyboards, reading heads, and displays is provided. Next, this chapter covers the 310’s main features and functions, including Calibration; Null procedures; and Density, Range, and Color Balance measurement.
This is useful in determining the plus/minus variation of the measured range as compared to a standard. Status A/M (Transmission only.) The 310 can be set at Status A response or Status M response. By simply pressing a keyand without mechanically changing opticsStatus can be switched between the two.
Using the 310 KEYBOARD VOCABULARY Your 310’s functions are controlled via the Keyboard on the Reading Head Arm. The Reflection Head Assembly (Model 310TR only) also has a Keyboard. Each has twelve keys: The 310 Transmission Densitometer Keyboard has three rows of four keys; the Reflection Head Assembly has four rows of three keys.

X-Rite 310 Operator Manual READING HEADS The instrument Keyboards are used to activate measurement functions and enter measurement values; however, actual measurements are performed using the Reading Head and Read Button on the Reading Head Arm; and the Reflection Head on the Reflection Head Assembly.
Using the 310 DISPLAY PANEL VOCABULARY Function and measurement information for both the 310 Transmission Densitometer and the Reflection Head Assembly is displayed in the Left and Right Display Panels on the 310. Along the outside edge of each display panel, functions related to the Keyboard keys are listed.
The first thing you should do before performing a measurement or a calibration is to check your Status response setting. Status responses are industry standards for densitometric measurements. Your 310 allows two response settings: Status A, which defines the response function for the measurement of...
Using the 310 CALIBRATING THE 310 Your X-Rite 310 is designed for long life and extremely stable readings. To maintain proper quality control procedures, you should calibrate your instrument. Once your instrument is calibrated, you should then periodically check calibration to verify measurement accuracy and proper operation of the unit.
Page 22
X-Rite 310 Operator Manual NOTE: It is possible to set Cal Lo on a density higher than 0.00D by entering the appropriate calibration number as shown in Step 4. This is required only for specialized calibrations. 6. Once the desired value appears, press CAL-SET.

“Cal Hi” measurement. The values listed for the check plaque are measurements traceable to certified reference standards maintained at X-Rite, Incorporated. NOTE: Make sure your check plaque is free of smudge marks and dust, which can dramatically affect measurement of the darker steps.
X-Rite 310 Operator Manual 8. The Display Panel displays the Cal Hi density value for Cyan (or the first color selected), and the Keyboard is automatically set in numeric format. As necessary, enter the Cal Hi density for Cyan, using a four- digit value.
Using the 310 NULLING (ZEROING) ON A STANDARD Before taking measurements, you should “null” or “zero” your instrument. This establishes the “zero” measurement according to which measurements that follow will be calculated. You can null by measuring a standard; or by manually entering the desired standard values.

Left Display Panel. Once the D x 10 function is activated in this step, all procedures that follow are the same. MEASURING RANGE (MINIMUM/MAXIMUM) In addition to normal density measurements, your 310 also provides Range and Minimum/Maximum measurement features. There are two ways to measure range using your 310:...
Page 33
Using the 310 6. Measure the second target sample in your series. Hold the measurement (the Read Button or Reflection Head down) until the display turns back on. The difference range value between these two measurements is displayed. Since these are the only two measurements so far, they are the Minimum and Maximum.
X-Rite 310 Operator Manual MEASURING COLOR BALANCE In addition to normal density measurements, your 310 also provides Color Balance measurement features. There are two ways to measure color balance using your 310: You can take an absolute color balance measurement that express the density of each color as the difference between the color and the highest of the three primary color densities.
Page 35
Using the 310 The display for the color with the highest measured density is set to 0.00. The other two color displays show the additional density required for these colors to “balance” with the high-density color to achieve a neutral gray color. The VIS display contains the greatest density value computed, which may be used to help adjust exposure time or illumination intensity.
X-Rite 310 Operator Manual USING MEMORY Your X-Rite 310 comes equipped with five display memory locations labeled M1 through M5for Status A Transmission, five Status M Transmission, and five for Status A Reflection. Density, Density x 10, and Balance each have five display memory locations for Status A Transmission, Status M Transmission, and Status A Reflection.

Clear-to-Send goes high before continuing. If Clear-to-Send is low when a PRINT command is given, the 310 will wait until the Clear- to-Send goes high.
Page 46
Cyan (Red) Magenta (Green) Yellow (Blue) The 310 is also capable of outputting data in this format while in the DENSITY x 10 function. The four density characters are output MSD to LSD. The Clear-to-Send/Busy pin is used as a Clear-to-Send for this format. In other words, if the Clear-to-Send is at a logic one (high) the densitometer will output data.
Input/Output (I/O) Functions SERIAL INPUT FORMAT Your 310 is equipped with an input that allows the 310 to be controlled or monitored remotely. Every function that can be performed at the keyboard plus a few functions not activated by the keyboardcan be activated via the serial input.
