Display unit functions

Measuring setup memory

The measuring setup can be registered as a program and saved (100 programs). These programs can be recalled with a single operation.

Multiple calibration data memory function

This function allows storage of 10 types of calibration data. In this function mode, up to 10 sets of 10 programs are available in hand.

Drill/endmill (odd number flute) diameter measurement

The diameter of drills or endmills that have an odd number of flutes can be measured by changing the parameter set up.

Automatic workpiece detection

This function automatically starts measurement when a workpiece advances into the specified measuring area.

Preset/offset

Sets the currently displayed measurement value to zero or a specified numeric value. This is useful, for example, if a difference in the diameters of a reference gage and a workpiece is to be allowed for in calibration, or if a dimension of a workpiece that exceeds the measurement range of the laser scan micrometer is to be measured.

Mastering

For continuous processing of high-precision workpieces, fine-adjusting the preset or offset value is called mastering. By specifying a mastering value, the total correction will be (zero-set/offset value) + (±mastering value). If a positive mastering value is specified, the displayed value for a workpiece diameter measurement will be greater than the actual value. If a negative value is specified, the displayed value will be smaller than the actual value.

Sample measurement

On a sample measurement the number of measurements will be defined (in the range of 2 to 999) in advance. From this sample, measurement various calculation results (mean, maximum, minimum, and range) can be derived. These measurements can be used for runout measurements on a revolving workpiece and simplified cylindricity measurements.

Arithmetical average/moving average

Arithmetical/moving average modes are provided to obtain the average of measurement values. On this type of laser scan micrometer, either of them can be specified before starting measurement. In the arithmetical average mode, the number of scans over which to take an averaging can be set at one of twelve steps between 1 (0.32 ms) and 2048 (0.64 sec). In the moving average mode, the number of scans can be set at one of seven steps between 32 (0.01 sec) and 2048 (0.64 sec), and the measurement value will be updated every sixteen scans on and after the second measurement, irrespective of the specified number of scans for averaging. The latter mode is suitable for judging the trend in the diameter or width of an endless workpiece, such as wire or tape from a measurement that requires a long period.

Measurement using segment specification

The following conventions are used to set up to the maximum of seven segments. However, if the transparent object measuring mode is set, no more than three segments can be set at one time.

Automatic measurement using edges

The edges created by scanning a workpiece can be used to program an laser scan micrometer. A maximum of 127 workpiece features, and 127 of the spaces between these features, can be used, which involves a total of 255 edges. This is most useful for measuring such things as IC chip leads or connector pins that are approximately equally spaced. This method cannot be applied to transparent objects.

External trigger signal input

By supplying a contact signal to the foot switch connector at the rear panel of the display unit, the measurement can be triggered.

Abnormal data elimination

If a piece of data significantly exceeds the tolerance limit because the workpiece or measuring unit is contaminated by a water droplet, oil droplet or dust, the piece of data will be automatically removed by this function.

Data output internal setting

By setting an interval (between 1 and 999 seconds) to continuous measurement in advance, data output will take place at each specified period of time.

Statistical calculation

With this function, multiple measurements are taken from the same type of workpiece, statistical values are calculated from the measurement results and quality evaluation is executed for each lot.

Data output

It has a standard RS-232C interface unit, allowing data to be output to an external PC or printer. Additionally, it has the standard I/O-Analog output interface that allows the laser scan micrometer to be connected to a sequencer, etc.
