Display Mode, EvaluationLarge Numeric Display ModeControl Chart Display ModeSpecification Limit Display ModeThe easy to read data display allows theoperator to discern important informationimmediately, positive avoidance oferrors ..., all these aspects have beentaken into consideration during thedesign of the instrument. The largenumeric display mode allows reading ofthe measurement even from a distance.Only the information necessary for themeasurement process is displayed. Thelast or selected measurement is enlargedallowing for clear readability.Data presentation in the form of qualitycontrol charts can be used to monitorand control production processes (e.g.,coating processes). The FISCHER-SCOPE ® MMS ® evaluation software providesfull SPC/SQC support capability.The control chart can be printed if required.Process capability factors Cpand Cpk as well as Kurtosis and Skewnesswhich are important to evaluate theprocess quantitatively, are calculatedcontinuously.The specification limits are freely selectableto allow for control of the processto be monitored using the control chartdisplay. Measurement subgroups areseparated by vertical bars. Useful for,e.g., scanning object surface.When a subgroup of measurements isfinished, the subgroup evaluation data isdisplayed at the push of a button. Theresult includes number and percentageof measurements that violate the upperand lower specification limits.EvaluationPrint FormProbability chartThe FISCHERSCOPE ® MMS ® saves theuser from having to do the sometimescomplicated and extensive mathematicalcomputations for the statistical evaluationof the measurement data. The evaluationis performed separately for the applicationand or over a section of blocks.Graphical evaluation menus as histogramand normal probability chart are usefullfor data analysis.The normal probabilitychart allows for a quick visual evaluationof the process, particularly useful to seeif measurements follow a normal distribution.Note: In this context, ‘measurements’refers to the mean value of several singleHistogramreadings, e.g., of random samples. Thesemean values have a normal distributionaccording to the central limiting valuetheorem of statistics if no systematicvalues are present.If the distribution is not normal, either thenumber of samples measured must beincreased, or the process is not understatistical control, or the process is notnormally distributed by nature. Suitablemeasures must be taken to eliminate possibleassignable causes still present. Onlywhen the measurements show normaldistribution can the usual known rules fora capability evaluation be applied.Example for a customer specific print formIn today’s quality conscious environment,user or customer specific documentationof the measurement result isa service the customer expects from hissupplier. Often, documentation of thecoating thickness and of other materialproperties is a stipulation.In addition to the standard print formtemplate included, a separate PC basedprogram allows the creation and downloadingof customer specific print formtemplates. In addition to the standardprint form template up to 5 customerspecific print form templates may bestored in the FISCHERSCOPE ® MMS ®and are readily accessible for final andbatch results evaluation.8
