Features

• Continuously monitors set-up values and provides readouts for two measurement values simultaneously
• Automatic workpiece detection starts measuring when a workpiece advances into the specified measuring area
• Capable of statistical analysis such as average, maximum value, minimum value, range (maximum to minimum) and more
• Segment measurement (7 points) or edge measurement (1 to 255 edge) can be selected
• Abnormal value elimination function removes false readings for more accurate measurements
• 100 tolerance values, preset values or settings can be stored for single operation recall
• Standard I/O and analog output interface to connect it to an operation controller or PLC used on a production line
• Standard RS-232C interface for connection to personal computers or printers
• Measuring setup memory: The measuring setup can be registered as a program (100 programs), saved, and can be recalled with a single operation
• 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 setup
• Automatic workpiece detection: Automatically starts measurement when a workpiece advances into the specified measuring area
• External trigger signal input: By supplying a contact signal to the footswitch connector at the rear panel of the display unit, the measurement can be triggered
• Data output interval 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
• Additional means of data output, including SPC, BCD and GP-IB output interfaces
• Multi-limit judgement: In addition to +NG, GO, and -NG judgment criteria limit values from limit 1 to limit 6 can also be set

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.

• 10 programs (a piece of calibration data) X 10 sets

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 gauge and a workpiece is to be allowed for in calibration, or if a dimension of a workpiece that exceeds the measurement range of the LSM 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 LSM, 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 seconds). In the moving average mode, the number of scans can be set at one of seven steps between 32 (0.01 seconds) and 2048 (0.64 seconds), 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.

Automatic measurement using edges

The edges created by scanning a workpiece can be used to program an LSM. 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.

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.

Simultaneous (dual-program) measurement

It is possible to measure two items simultaneously with one laser scan micrometer unit, and to output the data. This function can be used to simultaneously measure the outside diameter and runout of a bar that is rotating, or to measure the outside diameters of two cylinders or wires at the same time.
