1.2 Unlocking and Locking the Shoe The instrument is shipped from the factory with the shoe in the locked position. The shoe should always be locked next to the instrument when it is stored. To Unlock Shoe: 1. Hold shoe [1] against instrument. 2. Slide lock button [2] on bottom of unit towards the back until it stops, then slowly release the shoe [1]. To Lock Shoe: 1. Hold shoe [1] against unit. 2. Slide lock button [2] towards the front of unit until is stops, then release shoe.
1.3 Applying Power Battery Operation During battery operation power is applied automatically when a measurement is taken or if a key is pressed. The instrument automatically goes into a shut down mode to conserve battery life after 45 seconds of non-use. AC Operation As long as the AC adaptor is connected to the instrument, the 978 will remain On.
1.4 Charging the Battery Pack The 978 is powered by six nickel-cadmium batteries in a removable battery pack. The instrument’s batteries should be charged before use. The unit can be operated while the batteries are being charged. Before plugging in the AC adaptor, make sure that the voltage indicated on the adaptor complies with the AC line voltage in your area. If not, contact X-Rite or your Authorized Representative.
1.5 Function Selection ☛ There are five measurement functions that can be accessed by pressing the "FUNCTION" key. The "PASS/FAIL" and "555" functions are used for Textile QC operation and are covered in Section 3. The "SIMPLE COMPARE" and "ABSOLUTE COLOR" functions can be used for scratch pad type measurements. These two functions are covered in Section 4. - The desired function is selected by repeatedly pressing the [FUNCTION] key.
SECTION 2 INSTRUMENT POSITIONING & MEASUREMENT TECHNIQUES The variety of items that the 978 can measure is almost endless. However, in order to obtain accurate and repeatable measurements, the bottom of the shoe must be: * Parallel with the surface to be measured if the surface is flat. * Tangent to the surface to be measured if the surface is curved. The reason for this is that any movement during measurement can cause the reading to vary.
Instrument Positioning & Measurement Techniques . . .
SECTION 3 TEXTILE QC OPERATION Subjects covered in Section 3: * 3.1 Defining QC Setups * 3.2 Loading QC Setup and Reference Entry * 3.3 Pass/Fail and 555 Shade Tag Measurements Pass/Fail function displays the difference (numerically or by words) between the reference and sample. After a measurement is taken, a pass or fail signal will then be indicated dependent on the tolerances assigned in the QC Setups.
3.1 Defining QC Setups ☛ Setups must be defined in QA-Master if stored sample data is to be uploaded to QA-Master. Refer to Section 21 in QA-Master Reference Manual for procedure. The 978 will store up to 30 individual "setups" with user defined options. This provides a very versatile instrument that can measure a broad range of samples with different tolerancing needs. Simply call up the proper setup number and measure a reference.
Defining QC Setups . . . continued L*C*h° - color space is calculated from L*a*b*. The "L*" defines lightness, "C*" specifies chroma, and "h°" denotes hue angle. L*C*h° sometimes offers an advantage over L*a*b* in that it’s easy to relate to the earlier system that is based on physical samples, like the Munsell color space. XYZ - X, Y and Z are the CIE tristimulus values calculated per ASTM E308-90. X,Y and Z are used in calculating the other color spaces and indices.
Defining QC Setups . . . continued It is this automatic adjustment to the "volume of acceptability", compensating throughout the color space making CMC tolerancing so desirable, for matching human sensitivity to color difference. The CMC equation is summarized as follows: The volume of acceptance is defined by DECMC ≤ cf where: ∆L 2 ∆C 2 ∆H 2.5 DECMC =ι S + cS + S L c H Where SL, Sc, SH are the semi-axes lengths for a 1.0 DECMC ellipsoid.
Defining QC Setups . . . continued Illuminant/Observer (illum) - Is used to select the illum/obs combination that the setup will measure samples under. The available combinations are: C2, C10, D652, D6510, D502, D5010, A2, A10, F22, F210, F72, F710, F112, F1110, F122, and F1210.

SECTION 9 BAR CODE READER (Optional) Subjects covered in Section 9 are: * 9.1 Attaching SP78-200 Bar Code Reader to an Instrument * 9.2 Scanning a Bar Code * 9.3 Troubleshooting The Optional SP78-200 Bar Code Reader is used to scan bar codes. When the BCR is used in conjunction with an X-Rite instrument, a scanned bar code becomes a tag for the measurement(s) taken with the instrument. When the data is uploaded into a software program (e.g., QA-Master®) the bar code tag(s) become sample tag(s). 9.
9.2 SCANNING A BAR CODE Follow these guidelines for successful bar code scanning. 1) Turn on the X-Rite instrument. Be sure the instrument is in the Storage mode. (5°-45°) 2) Hold the BCR in your hand as you would a pencil. The BCR works best when tilted from 10° to 30°, although any angle from 5° to 45° will work. See Figure 2. Figure 2 3) Place the tip of the BCR on the white space to the left or right of the bar code. Drag the BCR smoothly and lightly across the bar code.
9.3 TROUBLESHOOTING The factory default mode can be restored if the SP78-200 BCR is placed into an unusable or unknown configuration. To restore the factory default mode: 1) Disconnect the BCR from the instrument. 2) Reconnect the BCR to the instrument. 3) Scan the default configuration bar codes shown in the SP78-200 Bar Code Reader Instruction Sheet (P/N SP78-510). Does the SP78-200 BCR have power? * A red light will be visible at the tip of the BCR if it has power.
Troubleshooting . . . continued Was the entire bar code scanned? * Drag the BCR through the entire bar code at a constant speed. Increase the scanning speed. Typically the BCR is moved too slowly. * Be sure the BCR scans the entire bar code. * Be sure the BCR maintained contact with the surface of the bar code. * Be sure the bar code is not damaged, dirty or worn. Try to scan an area without these defects.

APPENDIX D COLOR CHECK The color check procedure will help you track instrument color performance to assure measurement accuracy. Initially, the three patches on the standard should be measured once a day for a period of 10 days to determine the reference values. Thereafter, a periodic check (once a week depending on usage) is all that is required. Located on the back of the reference standard envelope is a color check label. The reference data should be recorded there for quick reference.
Color Check . . . continued 7) After 10 days average the white, blue, and brown values and enter data in the designated place on the color check label. 8) Enter date, illuminant, observer, aperture size, temperature, instrument model, and serial number on color check label. Note: Temperature of the reference standard should be maintained (±2°C) throughout color check sequence.
