3.1 CalculatingtheDi󰀨erencebetweenTwoMeasurement Values
Theresultofthecalculationofthedi󰀨erence(calculationresult)betweentwomeasurementvaluesis
displayed in the bottom row of the LCD.
Therearethreedi󰀨erentitemsforcalculatingthedi󰀨erencebetweentwomeasurementvalues.Usethe
method that matches your application.
y Calculatingthedi󰀨erencebetweenthecurrentandpreviousmeasurementvalues(regularcondition)
Intheregularcondition,thedi󰀨erencebetweenthecurrentmeasurementvalueandtheprevious
measurement value is displayed in the bottom row of the LCD.
For example, if the current measurement value is 45.000 mm and the previous measurement value is
25.000mm,[20.000]willbedisplayed.Thedi󰀨erencebetweenthecurrentmeasurementvalueand
the previous measurement value can be checked by reading the value displayed in the bottom row.
For details, see
"3.1.1CalculatingtheDi󰀨erencebetweentheCurrentandPreviousMeasure-
mentValues"onpage34.
Tips
If inside diameter, outside diameter, or plane scanning measurements are made, the center value of the
inside diameter, the center value of the outside diameter, or the median value for the displacement is used
respectively for the calculation.
y Calculatingthedi󰀨erencebetweenthecurrentmeasurementvalueandasetreference
Whenareferenceisset,thedi󰀨erencebetweenthecurrentmeasurementvalueandthereference
is displayed in the bottom row of the LCD.
For example, if the surface plate is set as the reference, and multiple circles are measured contin-
uously, the height of the center of each circle relative to the surface plate will be displayed in the
bottom row of the LCD.
For details, see
"3.1.2CalculatingtheDi󰀨erencebetweentheCurrentMeasurementValueand
a Set Reference" on page 35.
Tips
The measurement value varies according to the type of measurement.
• Inside diameter measurement: Center of the inside diameter
• Outside diameter measurement: Center of the outside diameter
• Plane scanning measurement: Median, minimum, or maximum value
