5. Calibration State-of-the-art technology and thereference-beam principle mean thatcalibration is needed onlyinfrequently. We recommend acalibration interval of two months.

Calibration is also necessary:

• at the first startup

• in the event of a drastic change inambient temperature (for example,after moving the unit to a new site)

• if "Please Recalibrate" appears onthe display (for example, afterstored calibration values havebeen modified).

To ensure accurate calibration, useonly original standards fromBYK-Gardner.

Do not touch the reference surface.Protect it against scratching.Even with careful treatment,ambient conditions may alter astandard’s values over time. Forthat reason, have Customer Servicecheck your standards regularly(once a year) against primarystandards.

Make sure the values displayedduring calibration match the data forthe standards you use, in order toavoid mixing up or accidentallychanging the calibration values (seeSection 5.3).

To calibrate:

CAUTION: Make sure thecalibration standards are cleanand free from scratches!

5.1 Additional Standards forMonitoring Test Equipment

To check proper operation of theinstrument, measurements withspecial test standards should beperformed at regular intervals(about once every three months).The appropriate test standards arelisted in the Ordering Guide.

The displayed readings should fallwithin the specified values for thestandard. If they do not, check thatthe standard was clean and that thedevice was properly calibrated. Ifcleaning the standard andrecalibration do not correct theerror, please contact CustomerService.

5.2 Cleaning the Standards

Calibration with a dirty or damagedstandard may severely affect theaccuracy of measurements.

Standard surfaces are very delicate.Be very careful when cleaningthem.

Use a fresh, soft cloth, and washthe standards in running or standingcold water. Do not apply ascrubbing action or heavy pressure.Make sure no large particles thatmight damage the surface adhere tothe cloth.

Do not use aggressive cleaners likesolvents, rubbing alcohol,trichloroethylene, benzine, or strongalcohols, acids or lyes. Mostchemical cleaners or polishes willcause damage.

To remove stubborn dirt, add a littlehousehold dish detergent to thewater. Rinse with distilled water.Dry with compressed air and blowoff any dust or lint.

Never rub the standard dry! Therubbing action may causescratches from surface dust.

Precise calibration is possible onlywith flawless standards. If visualappearance or measurement errorssuggest that a standard is compro-mised, we’ll be glad to check it.

9. Parameters Appearance of TransparentMaterials

When a parallel beam of lightstrikes a transparent specimen, anumber of effects may result,depending on the nature of thematerial:

• Homogeneous material with asmooth surface

Some of the incident light will bereflected from surfaces, and somewill pass through the specimenunaltered. The specimen willappear glossy and crystal clear.

The intensity of the transmittedlight will be diminished by theinherent absorbance of thematerial, dyes or pigments.

• Rough surfaces and internalscattering

Diffuse scattering will decrease anobject’s imaging quality. Particlesinside the material or structures on

its surface may act as "scatterers".The more scatterers are present,the greater the amount ofscattered light; the distribution ofscattered light in space is relatedto the scatterers’ size distribution.The scattering behavior of aspecimen will determine itsappearance. Two differentcomponents can be clearlydistinguished visually (Fig. 1).

• Wide-angle scattering - Haze

Wide-angle scattering diffuseslight uniformly in all directions, andthe light intensity per angle issmall. This reduces contrast andresults in a milky or cloudyappearance. This effect is calledhaze.

• Narrow-angle scattering – Clarity

Narrow-angle scattering deflectslight in small angles, so that thelight intensity is concentratedwithin this narrow angular range.

Contours may be distorted andseem less distinct. This effect,called clarity, influences theresolution of fine details.

Unlike haze, clarity is distance-dependent, and deteriorates asthe distance between thespecimen and the observed objectincreases (near/far transparency).

Transparency Evaluation Criteria

The appearance of a transparentproduct is a function of gloss, colorand transparency. Essential criteriaof transparency are totaltransmittance, haze and clarity.

Total transmittance is the ratio oftotal transmitted light to incidentlight. It is reduced by reflectanceand absorbance.

Measurement Principle

A beam strikes the specimen andenters an integrating sphere(Fig. 2). The light, uniformlydistributed by the matte whitecoating on the sphere wall, ismeasured by a detector. Totaltransmittance is measured with thesphere outlet closed, and haze ismeasured with the outlet open. Aring sensor in the outlet openingmeasures clarity. The entire

measurement sequence iscontrolled automatically.

Notes:

• For values of less than 10 %, themeasurement range is auto-matically switched over to adisplay with two decimal places.

• In taking a measurement, themean is taken across the illumina-ted surface of the specimen. Sinceit cannot be assumed that opticalcharacteristics will be uniform overthe entire surface of the specimen,we recommend taking readings ata variety of points on the speci-men, and using the mean.

• There is little sense in takingreadings from dirty, scratched orotherwise damaged areas of thespecimen, unless you want toobtain the measurements as anindication of the severity of suchdamage, for example inmeasuring abrasion resistance(Taber Abraser).

• Specimen surfaces must be asplane-parallel as possible; awedge shape will deflect light.

• When taking comparativereadings note the specimenthickness, since absorbance andscattering increase in directproportion to thickness.

• Differences in reflectioncharacteristics may affecttransparency measurements.Particularly when specimens areglossy on one side and dull on theother, the same surface shouldalways be directed toward thesphere aperture.

• Positioning the specimen at thesphere inlet reflects light from thespecimen within the sphere. Thisimproves the sphere’s efficiency,and the measured totaltransmittance will be slightlyhigher.For completely clear specimens,you can obtain precisetransmittance values by keepingthe specimen at the clarity portduring the transmittancemeasurement.Specimens with high levels ofscatter should always be placed at

the haze port. Here werecommend calibrating theinstrument with a previouslymeasured transmittance standard(see Section 5.3). This standardmust have a surface reflectivitysimilar to that of the specimens tobe measured.

• Optical-quality cuvettes withplane-parallel walls and an edgelength of at least 50 mm may beused to take readings on liquids.Appropriate cuvettes are listed inthe Ordering Guide.

• In practice, it may be significant toknow whether scattering is causedby internal scatterers or surfacestructure. In these cases, surfacescattering can be eliminated byimmersing the specimen duringthe readings in a liquid with thesame refractive index as thespecimen. Only bulk scattering willthen come into play.
