PRECAUTIONS

1. Safety Precautions The Measuring Unit connected to the Display Unit uses a very low power laser.

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

1) An applicable laser product class of the IEC standard: a Class 2 laser product uses a visible laser (maximum power: 1.3 mW for scanning; laser device: semiconductor laser; wavelength: 650 nm).

2) Do not look directly into the laser beam. (Even if it seems that no light is being emitted from the emission window, do not look into it.)

3) If measuring flat objects with mirror finishes, avoid looking at the reflection on the surface.

4) Close the beam shutter when the instrument is not in use.

5) Do not remove the laser class identification labels attached to the Measuring Unit.

6) Before using this unit, carefully read the “Measuring Unit Specifications” and “Precautions on Use of Laser” sections provided in the manual supplied with the Measuring Unit.

2. Before making the connection between the Measuring Unit and the Display Unit, turn off the power. If an optional device is to be connected to this system, make sure that the optional device is also turned off.

3. Firmly tighten the screws of the cable connectors and interfaces to ensure shielding.

4. Do not touch the terminals of the connectors, otherwise contact may be poor.

5. Positively ground the Display Unit.

6. An error display may appear during operation. However, it may not always indicate a fault. If an error display appears, consult the “Maintenance and Inspection” section.

7. Unplug the power cord when a system failure is encountered.

Do not open the covers provided on the emission unit and reception unit.

INSTALLING CONDITIONS

The Mitutoyo Laser Scan Micrometer LSM-6100 series is both a precision optical instrument and a precision electronic instrument, and this unit is the instrument suitable for indoor use as well. Therefore, it must be carefully installed and the following conditions must be taken into consideration to attain the highest possible accuracy.

1. Vibration Install this unit if possible in a place where it will not be subject to vibration. If this unit is used for a long period of time in an environment where there are significant vibrations, the precision parts in this unit may be affected, resulting in the deterioration of measuring accuracy.

If this unit has to be used in an environment where vibration is significant, measures such as the laying of a vibration damping rubber pad under the unit must be applied to reduce the effect of vibration.

2. Dust Dust and airborne particles at the installation site adversely affect optical parts including the protective glass and electronic parts of the Measuring Unit. Place this unit in a place with as little dust and as few airborne particles as possible.

3. Direct sunlight If this unit is subjected to direct sunlight, the heat may deform this unit and affect the measuring accuracy.

4. Draft from air-conditioning equipment

5. Ambient temperature and humidity

WARRANTY

If this unit must be placed by a window where it will be subjected to direct sunlight, protect the unit by shading it.

If the measuring area is subject to such as warm or cold draft from any air-conditioning equipment, the laser beam may be artificially refracted due to the unevenness of ambient air concentration, affecting the measurement accuracy.

If this is the case, block the draft in the mid-way to the measuring area by such as a curtain, etc.

This unit must be operated in an environment where the temperature is between 0 and 40˚C and the humidity is between 35 and 85% RH. Avoid installing this unit where there is significant temperature or humidity change.

Significant temperature and humidity changes may reduce measuring accuracy.

In the event that the Mitutoyo Laser Scan Micrometer (LSM) should prove defective in workmanship or material, within one year from the date of original purchase for use, it will be repaired or replaced, at our option, free of charge upon its prepaid return to us.

If the unit fails or is damaged because of the following causes it will be subject to a repair change, even if it is still under warranty.

1. Failure or damage due to inappropriate handling or unauthorized modification.

2. Failure or damage due to transport, droppage, or relocation of the machine after purchase.

3. Failure or damage due to fire, salt, gas, abnormal voltage, or natural catastrophe.

This warranty is effective only where the machine is properly installed and operated following this manual.

INTRODUCTION

1.1 Outline

This system is an accurate, non-contact measurement system capable of measuring workpiece dimensions at a high speed using a highly directional scanning laser beam.

This non-contact optical measuring system is capable of measuring workpieces which are difficult to measure with conventional measuring instruments. It performs simple and accurate measurement of brittle or elastic objects, objects at high temperature, objects which must be kept clean, and soft objects which may be deformed and suffer dimensional changes under the measuring forces used.

1.2 Foreword

This user’s manual primarily explains the functions of the Display Unit. For information about the safety precautions, specifications, dimensions, standard accessories, and options for each Measuring Unit, refer to the user’s manual supplied with the Measuring Unit.

This chapter describes the Laser Scan Micrometer (LSM) models and nomenclature of the Display unit and the Measuring unit.

1.2.1 Measuring units available

This Display Unit can be used with the following Measuring Units.

sledoM

S005-MSL S105-MSL S305-MSL S605-MSL S215-MSL S615-MSL

1.2.2 Using the Measuring Unit separately

All models, excluding the LSM-500S, can be used separately (the laser emission unit and reception unit can be separated) by removing the mount from the Measuring Unit.

For information about using an LSM separately, refer to the measuring unit user’s manual.

2. The terminal located at the left end of the power input terminal and marked (by a

symbol ) is the grounding terminal to keep the potential of signal line of this unit equal with other instrument connected. It is used to enhance resistance against electrical interference.

NOTE Precautions for wiring the terminal block

1. If wiring the I/O analog terminal and Power input terminal, do not directly touch the

output terminals of the terminal block by hand, which has static charges, because the internal circuit may be damaged by static discharge. If your hands are charged, discharge the static energy by touching the metallic surface of the Display Unit in advance. In addition, unplug the power cable from the outlet before commencing wiring.

2. After wiring has been completed, close the protective cover.

3. Do not touch the input terminals on the terminal block during operation, otherwise

an operation error may result.

OPERATIONS

This Display Unit is provided with many useful functions that can be customized according to the user's needs.

This chapter describes these functions and key operations.

3.1 Outline of the Operation Modes

3.1.1 Measurement Principle

In order for the user to understand the measurement principle of the LSM, the following paragraphs describe about the system block diagram, segments (measurement positions) and measurement interval (measurement time).

3.1.1.1 Overview

Unlike light emitted from natural sources, a laser provides extremely fine, rectilinear beams which do not diffuse (coherent light beams).

Using the properties of the laser beam, the Mitutoyo Laser Scan Micrometer (LSM) moves a scanning laser beam over the workpiece and determines its dimensions by measuring the duration in which the beam is obstructed by the workpiece.

The configuration of the system is shown in the above block diagram. A laser beam emitted from the laser oscillator is directed at the polygon mirror which rotates at high speed and is synchronized by clock pulses. The laser beam that is reflected by the polygon mirror is then collimated by the collimator lens towards the workpiece. As the polygon mirror rotates, this horizontal beam scans the workpiece and the beam not obstructed by the workpiece will reach the photoelectric element through the condenser lens and induce an output voltage in the photoelectric element. The output voltage will change according to the duration over which the laser beam is obstructed. Counting pulses generated during that period are used to determine the dimension of the obstructed portion. This data is sent to the CPU for processing and the dimensions are displayed digitally.

Consequently, either the dimensions of the workpiece (shadowed areas) or workpiece clearances (highlighted areas) can be determined by specifying the segments to be measured.

TIP In the system block diagram described in the previous page, the laser beam passed

through the collimator lens is made parallel and, at the same time, stopped down so that the beam diameter is minimized at the measurement position.

3.1.1.2 Setting the segment

Set the objective portion of a workpiece to be measured. The highlighted and shaded portions created when the laser scans over the workpiece are

controlled with each assigned number. In the basic setup a selection must be made from one of two cases: case where there are 1 to 4 highlighted and shaded sections, and case where there are 1 to 127 similar sections. In the former case the portions are controlled through the segment number, and are simply called segments. In the latter case the portions are controlled by the edge number (edge number is between 1 and 255) and called edges. Edge numbers equal to or greater than 256 are not available.

3.1.1.3 Measurement interval (measurement time)

A measurement interval (measurement time) varies depending on the averaging method and the number of scans selected for the measurement data.

There are two types of averaging method: the arithmetical average and the moving average. Select the one best suited for the user’s purpose.

1) Arithmetical average

• If a moving workpiece is measured, the OD of the workpiece is determined by averaging the measured data taken from each section (a: first measurement, b: second measurement,

.... n: nth measurement) of the workpiece the specified number of averaging times, as

shown below.

2) Moving average

second measurement

ban

Moving workpiece

. . .

nth measurement

Moving direction

• One of the following number of averaging times can be selected: 1, 2, 4, 8, ....1024, 2048.

(If extra fine wire measurement is specified in the basic setup, the number of averaging times can be selected from between 16 and 2048.)

• This is suitable for measuring a still object or the run-out of rollers, etc.

In the moving average method, a measurement interval identical to that in the arithmetical average is divided into finer sections such as a1 (1st measurement), a2 (2nd measurement), -

- - , an (nth measurement). Each measurement is performed almost in parallel. If, for ex-

ample, the number of averaging times is set to 512, the first measurement requires the amount of time that corresponds to 512 scans. However, for the second measurement onward, only the time for 16 scannings is required. With respect to a workpiece with a changing OD, this method provides data with smooth variation because of the many pieces of data, and also quickly detects the trend of workpiece OD variation.

3.1.2.6 Measurement mode

This mode can be divided into the following operational states:

1) Measurement in the ready state

• This is the measurement mode that is entered immediately after the power is turned on or if another measurement mode is aborted by pressing the signal from the I/O interface or the “CL” command from the RS-232C/GP-IB interface).

• It is used to establish setups for calibration and available functions, which are not part of the basic setup items, or to enter another measurement mode including single-run measurement.

• Usually GO/NG judgment and analog output will not take place for measurement in the ready state, however, these specifications can be made in the basic setup mode.

• Measurements in the ready state are unavailable for statistical processing.

2) Single-run measurement

• If the the RS-232C/GP-IB interface) is pressed, one session of measurement is performed and the results will be automatically subject to GO/NG judgment and analog output. In addition, the measured data will be outputted for the RS-232C/GP-IB interface, Digimatic Output Unit, and printer. The measured data will be held (latched for the specified period) in the display.

• This data will be available for statistical processing.

IB interface) is pressed halfway, the measurement is aborted and the ready state is returned to.

• The measurements are available for statistical processing.

4) Continuous measurement with a term specification

• This will take place where RUN input from the I/O interface has been assigned so as to start a term-specified continuous-run measurement in the basic setup.

• Repeatedly performs single-run measurement while RUN signal input continues, which is basically the same as the continuous-run measurement. Therefore, hereafter, continuous-run measurement includes the ones with a term specification.

• The measurements are available for statistical processing.

No. 99MBC095A

5) Zero-run measurement

• A measurement where the number of samples is set to “0” is called a “zero-run measurement”.

• If the

DATA C/RUN

key (otherwise input RUN via the I/O interface or the “R” command via the RS-232C/GP-IB interface) is pressed, single-run measurement is started and repeated until the

DATA C/RUN

key is pressed again (or RUN is inputted via the I/O interface or the “STOP” command is inputted via the RS-232C/GP-IB interface). From the measured data the calculation items (mean, maximum value, minimum value, and range) that have been set for the sample measurement will be calculated and the resulting data will be automatically subject to GO/NG judgment and analog output. In addition, the measured data will be outputted for the RS-232C/GP-IB interface, Digimatic Output Unit, and printer. The measured data will be held on the display.

• The measured data are available for statistical processing.

• This is suitable for run-out measurement and cylindricity measurement.

6) Sample measurement

• A measurement where the number of samples is set to “2~999” is called a “sample measurement”.

• In practice this will take place as a single-run measurement or a continuous-run measurement (with a term specification). From the measured data the calculation items (mean, maximum value, minimum value, and range) that have been set for the sample measurement will be calculated and the resulting data will be automatically subject to GO/NG judgment and analog output. In addition, the measured data will be outputted for the RS-232C/GP-IB interface, Digimatic Output Unit, and printer.

• The measured data are available for statistical processing.

• This is suitable for run-out measurement and cylindricity measurement.

7) Statistical processing

• Measured data from single-run and continuous-run measurements can be statistically processed (i.e. the number of measurement times, standard deviation, maximum value, minimum value, mean, and range are calculated). These statistical processing results can be outputted for the display, printer (statistical memory for all programs will be cleared after printout), and RS-232C/GP-IB interface.

• Press the

STAT/S.E

key (or input “ST” command via the RS-232C/GP-IB interface) to start statistical processing, and press it again (or input the “NST” command via the RS232C/GP-IB interface) to terminate statistical processing.

3.2.4 Setups according to the property of each workpiece

For measuring workpieces that transmit light or have a dimension smaller than the diameter of the scanning beam it is critical to make setups that take into account the properties of the workpiece.

3.2.4.1 Transparent object (Workpiece that transmits light)

a) Round bar

• Workpieces such as fiber optics and glass tubes are more or less transparent, while

workpieces made of steel are not. This requires different segment settings. The segment settings for an opaque object and a transparent object are as follows:

• For measuring a transparent plate-shaped workpiece Take the following precautions:

1. Incline the workpiece.

By inclining the workpiece it is possible to attain a sharp edge from the light contrast. In this case: Measurement : W = W0 (workpiece dimension) x cos θ

2. Chamfering

Chamfer the workpiece edge by W. W will vary depending on the model. Always use values larger than those in the table below.

3. Changing the SHL

• With the reference workpiece set up on the Measuring Unit, connect the oscilloscope to the [SCAN SIG.] terminal on the rear panel of the Display Unit and observe the signal.

• SHL is the signal level for detecting a workpiece. Changing the level from the standard level of 50% to a level such as 75% will enable the measurement of a transparent sheet. The measurement accuracy, however, will be degraded since measured data fluctuates according to the edge conditions of the sheet.

• It is possible to set the SHL level between 5% to 95% for "7 SHL" by setting up "7 ADD"="USE" and "7 DLC"="OFF" in the expanded basic setup.

NOTE Measuring accuracy differs from that of the standard set up.

• Measured data differs with the change of the SHL. Perform calibration again if the SHL setting has been changed.

• Measurement error can be reduced by performing calibration with the reference standard, the edges of which have been made in the same condition as those of the sheet to be measured.

IMPORTANT • When the SHL (signal level for detecting a workpiece) is modified, the measure-

ment accuracy will be inevitably reduced, since the measured data may easily fluctuate with the edge conditions.

• Once the SHL (signal level for detecting a workpiece) has been modified, always perform another calibration.

• If an identical edge form is selected for both for the calibration standard and workpiece (sheet), it may be possible to reduce these measurement errors.

3.2.4.2 Ultra-fine wire measurement

• In the special ultra-fine wire measuring region, a clear shade can not be obtained because a workpiece, with a finer diameter than that of the laser beam at the focal position, must be measured. Therefore, this wire diameter must be calculated according to a special algorithm. This requires the following restrictions to be taken into account in the basic setup where an ultra-fine wire measurement is designated.

a) Measuring interval (measurement time)

Note that the measurement time for the first measurement becomes 0.02 seconds longer than the first interval since the wire diameter must be identified at the start of ultra-fine wire measurement.

• Single-run measurement: (Measurement interval + 0.02 seconds)

• Continuous-run measurement: (Measurement interval + 0.02 seconds) for the first

b) Number of averaging times

Select a number between 16 and 2048.

c) Designation of the objective portion of workpiece to be measured

Only a segment specification is allowed, but an edge specification is not. If an edge specification has been made before the setup for the ultra-fine wire measurement is established, it is automatically changed to segment specification. In other cases where multiple segments are set for the LSM-500S, the minimum allowable measuring range begins at 0.1 mm. In addition, if a workpiece measures less than 0.1 mm, only one segment can be specified.

d) Others

In extra-fine wire measurements, simultaneous measurement, dual measurement (measurement using two measuring units), workpiece automatic detection, and group judgment can not be set up. Setups for these functions are automatically canceled.

• The measuring position is a critical factor for ultra-fine wire measurement. Always perform the measurement at the focal position of laser beam while referring to Section

5.2.2 “Displaying the measuring position”. In other cases where a fine gap is to be measured, the amount of laser light may be insufficient, resulting in unstable measurements. Refer to Section 4.4, “Recording the Amount of Light”, and store the amount of light without the workpiece and fixtures in the optical path.

• The following table shows the measuring ranges if “Not performing ultra-fine wire measurement” is designated on the LSM-500S.

Page 36

3. DISPLAYS AND KEY OPERATIONS

IMPORTANT 1. For measuring ultra fine wire with a diameter thinner than that of the laser beam,

the SHL (signal level for detecting a workpiece) needs to be changed according to the workpiece size (external diameter).

2. Since the SHL is changed to the level most appropriate for the workpiece size, multiple workpieces or workpiece fixtures existing within the laser scanning range may disable the detection of a workpiece less than 0.05 mm in diameter. Exercise care so as not to produce multiple shadows within the scanning range.

3. Also, if the segment is set to 1 or 3, it is not possible to determine the position of a fine workpiece less than 0.05 mm in diameter, runout, and bending.

3.2.5 Measurement of an odd-numbered-edge cutting tool

• This function is used to measure the diameter or run-out of cutting tool (drill or end mills, etc.)that has an odd number (3, 5, ...) of cutting edges.

• When the outside diameter, øD, of an odd-numbered-edge cutting tool is measured, the measurement errors as shown in the figure below will result if this LSM unit is set to Segment 2 (normal outside diameter measurement) for measurement. To avoid these errors, in this case, first install the reference bar as shown below, then perform the measurement while rotating the odd-numbered-edge cutting tool. Calculate the outside diameter of the odd-numbered-edge cutting tool by obtaining the difference between “Peak value of Segment 2+3” and “Bottom value of Segment 3” while the cutting tool rotates more than one turns from the beginning of measurement. Then save the bottom value of Segment 3 into memory as many as the number of cutting edges being set, and calculate the range (maximum - minimum) as the “run-out”.

• If the dual-type add-on unit is not set, the setup guidance for it will not be displayed.

• Suspended use of Measuring Unit

For repair or adjustment services one of the Measuring Units employed for dual-unit measurement may be suspended from operation. If this is the case, turn off the power and disconnect the Measuring Unit. If the Measuring Unit 1 has been disconnected, the Measuring Unit 2 must be connected to the TRANSMITTER-1 while re-installing the corresponding ID unit in place. After removal of one measuring unit, designate in the basic setup (4.1.2.3 Selecting an setting the function in the B2 mode: d. Setting the dual-unit measurement). If one Measuring Unit is removed without this designation, “Err-8” will result and the other Measuring Unit will also become inoperable. Note that suspending one Measuring Unit will cause the calibration values and function setups to be reset to their defaults.

c) Example of units positioned back to back

• Position two Measuring Units back to back as shown in 3) above to measure a transparent object with the DF-type setup. Transparent objects may not be measured with units facing each other or stacked one on top of another.

• For information about techniques to improve the measuring accuracy refer to the measuring unit user’s manual.

• Calibration and combined offset a) Separate calibration for each Measuring Unit

Perform the calibration after selecting Segment (1 ~ 3) at the Measuring Unit 1 side with the least significant digit of program number set to between 0 and 4 for Measuring Unit 1, and Segment (5 ~ 7) at the Measuring Unit 1 side with the least significant digit of program number set to between 5 and 9 for Measuring Unit 2, respectively.

b) Combined calibration

In addition to being able to perform separate calibration for each Measuring Unit, the DF-type setup allows the use of combined calibration where segments are assigned over two Measuring Units. This combined calibration is effected from either combination of segments (1 + 5) or (1 + 7). Note that cancellation of separate calibration will also cancel the combined calibration.

IMPORTANT Since the reflection light from a large-diameter workpiece (skip phenomenon) is

generated in DF-type measurement, the accuracy decreases to some extent, compared with the linearity of each measuring unit. The following figure shows that undesired values e1 and e2 are generated due to reflected light. The undesired value (e1, e2) increases with the diameter of the workpiece (e2 > e1). This depends on the reflectivity of the surface. Therefore, if each measuring unit is calibrated independently using a small diameter gage, an error may result if a large diameter is measured.

If a large-sized workpiece is measured using the DF-type setup, combined calibration will ensure more accurate measurment.

c) Combined preset

While combined calibration is used to measure workpieces of various sizes, the combined preset is used to measure workpieces with a dimension close to the reference gauge. Since, at a combined preset, separate values can be set for each program number, a maximum of 100 kinds of workpieces can be registered. To perform the combined preset make the measuring positions of the reference gauge and workpiece as consistent as possible. Designate the combined preset by combining segments such as (1 + 5) or (1 + 7), and set the direction to negative (1). However, if this is coupled with a combined calibration, set the direction to positive (0).

3.2.7 Latch (holding) of the displayed value

3.2.9 GO/NG judgment

• All the measured data are subject to GO/NG judgment. To enable, set the GO/NG judgment criteria in advance.

• The following settings can be made in the basic setup. a) The method of tolerance judgment can be selected from (Lower limit value and upper

limit value), multi-limit selection (7 limits) and (Target value and tolerance values: upper tolerance value and lower tolerance value). To output the judgment result with the multi-limit selection it is necessary to select the optional Second Analog I/O Interface.

b) Simultaneous measurement can be specified. To do this, it is necessary to select the

optional Second Analog I/O Interface for tolerance result output.

c) For (Target value and tolerance values), the user is permitted to select whether the

target value is to be copied to the reference value. If it is, the setup guidance for the reference value will not appear.

d) Even in the ready state it is possible to select whether tolerance judgment and analog

output are performed. If they are, tolerance judgment and analog output will take place in the ready state, however, these data are not available for statistical processing.

e) Abnormal data elimination, tolerance judgment, group judgment, and analog output can

be performed in a single-run measurement, zero-run measurement, sample measurement, and continuous-run measurement (with a term specification). The judgment result will be indicated by the -NG (red LED), GO (green LED), and +NG (red LED) indicators and outputted to the I/O interface and RS-232C (including printer)/GP-IB interface.

3.2.10 Abnormal data elimination

• The abnormal data elimination function eliminates measurements that are very different from those specified for the machined workpiece, from the measurement data (neither the measurement is displayed nor is data output performed). If, for example, the grindstone of a centerless grinder is controlled based on the measured data from the LSM, it is possible that a large measurement error may be created due to the coolant used with the workpiece. As shown in the figure below where foreign matter (with a height of h) adheres to within the averaging region L of the workpiece (with a diameter of D). An abnormal outside diameter results in the region of l and the displayed measurement will be (D + lh / L). As the result the grinder is subject to improper control that involves some error.

Because the use of this function can eliminate abnormal measurement data generated due to the adhered foreign matter, the grindstone can be controlled and fed properly.

• Judgment of valid data or abnormal data will be performed at each measurement interval. Valid data includes those satisfy the following relation: Lower abnormal limit ≤ (Measurement) < Upper abnormal limit. All other data will be discarded as abnormal data.

• In the basic setup select whether this abnormal data elimination function should be used. If it is the setting of (lower abnormal limit, upper abnormal limit, and count value) should be performed before actual tolerance judgment. This count value indicates the number of pieces of abnormal data that occurred until the alarm will be issued. This alarm output will be sent to the optional Second Analog I/O Interface by CNT form (The alarm will not be issued if the count value is set to zero).

• Abnormal data elimination function effects in single-run and continuous-run measurements.

• If “Err-0” (specified workpiece not present) is displayed in the sample measurement, the valid data collected will be discarded.

NOTE If a long series of abnormal data appears, measurement can no longer be continued

since most of the measured data must be eliminated. To avoid this problem, always monitor CNT output.

a) Preset

b) Zero-set

c) Direction

3. DISPLAYS AND KEY OPERATIONS

• In this system the operation of setting the reference gage dimension is called the preset operation.

• This function is applied to measure the absolute dimension of a workpiece.

• Setting the reference gage dimension to “0.0” for the purpose of comparing it with a

workpiece dimension is called the zero-set.

• This function is applied to measure a deviation from the reference gage dimension.

Depending on the objective portion of measurement of a workpiece, the positive direction (set as “0”) or negative direction (set as “1”) must be set. If, for example, the shaded portion of D in the following diagram is measured, the direction must be set as positive (0). If the highlighted portion (gap) of W is to be measured for determining the workpiece dimension L, the direction must be specified as negative (1).

Set as positive (0) Set as negative (1)

• Preset operation takes about 1 second to determine the compensation value by measuring the reference gage.

• Preset value will be ineffective if the segment or edge number is changed (Preset value is unique to each segment or edge).

• If the objective workpieces are high-precision gages that are machined successively, the above described preset/zero-set values may need to be fine-adjusted to the master. This fine-adjustment is called mastering. After mastering, the total compensation value will be:

(Preset value/zero-set value) + (±Mastering value)

Setting a positive (+) mastering value allows the measurement of a workpiece OD to be greater than the raw measurement, and setting a negative (-) mastering value allows the measurement of a workpiece OD to be smaller than the raw measurement.

• Because no measurement is required for this mastering, the reference gauge is not required either.

• Set the reference gage dimension with the preset function and perform mastering.

3.2.13 Reference value

• This function is used to output deviations (measured data - reference value) between the reference value and the actual measurements of a workpiece for the Analog I/O Interface. Before analog output, set the reference value and the scale value (gain).

• Measured data is outputted as analog signals at a full scale of ±5V. Analog signal = (Measured data - reference value) x scale value (gain)

• In the basic setup the following conditions can be set. a) Whether the target value of GO/NG judgment is be copied to the reference value. If this

is selected, the setup guidance for the reference value will not be displayed, so only the scale value must be set.

3.2.15 Automatic workpiece detection <OD detection method, Position detection method>

• Automatic workpiece detection is performed for continuous-run measurement, where measurement starts with no specified workpiece present (Err-0), then proceeds to automatic detection of the workpiece, followed by measurement repeated number of times. No specified workpiece present (Err-5) also refers to the workpiece outside the upper and lower detection limits.

• Whether automatic workpiece detection is performed is specified in the basic setup mode. If automatic workpiece detection is specified, the number of scanning times for detection must be specified from among 1 and 16. Select 16 times if detecting precision workpieces. If automatic workpiece detection is not specified, no further setting is necessary.

• Automatic workpiece detection setup includes the number of measurement times, invalidation period, upper and lower detection limits. Set both the upper and lower detection limits.

• To exclude the measured data of such as chamfered portion of the workpiece, invalidation period can be set within the range from 0.001 sec to 9.999 sec.

1) OD detection method

• This is used to automatically detect a workpiece that enters the laser scanning plane perpendicularly.

• For actual detection of a workpiece the displayed measurement (after calibration and preset) is used.

• One session of automatic detection consists of no workpiece being detected, detection of a workpiece with a dimension that is within the detection range (between the upper and lower detection limits), an invalidation period required to exclude invalid dimensions (of chamfered portions, etc.) from the measurement, and effective measurement for the specified number of times. The final measurement result will be latched (held) on the display. Once entering the effective measurement the upper and lower detection limits will no longer be checked.

• The speed of workpiece detection (i.e. the number of scans) can be specified as either 1 or 16 in the basic setup.

• Use 16 times in the following cases: * If connecting bars are used between workpieces for feeding convenience and for

setting appropriate intervals between workpieces, and, if the difference in the outside diameter between the workpiece and the bar is insufficient.

* If the feed rate is low.

• The following diagram is an example where a workpiece with a chamfered outside diameter of D mm and a length of ᐉ mm moves at a velocity of V mm/s.

Setting example:

• Lower detection limit: L < (a +D) / 2

• Upper detection limit: H > Upper limit of the measuring range or 1.1 D

(This setting may be omitted.)

• Invalidation period : T > (c / V) ms

•

Number of measurements: N < (ᐉ - 2c) x 0.8 (safety factor) / measurement interval / V

2) Position detection method

• This is used to automatically detect a workpiece that enters the measuring region in the laser scanning plane in the same direction of the scan.

• Workpiece detection is performed with one scan, and 16 scans can not be specified (If specified in the basic setup, the specification will be ignored).

• One session of automatic detection consists of the detection of no workpiece, detection of a workpiece edge with a dimension that falls within the detection range (between the upper and lower detection limits), an invalidation period required to exclude invalid dimensions from the measurement, and effective measurement for the specified number of times. Once the effective measurement has been entered, the upper and lower detection limits will no longer be checked.

• In the following diagram, workpiece positions (a) and (b) result in no workpiece being present, and in (c) it is judged that a workpiece is present.

Setting example:

Assuming the workpiece diameter as D (mm) and the moving speed as V (mm/s):

• Lower detection limit: L > (Laser scanning range - measuring region) / 2

• Upper detection limit: H < (Laser scanning range + measuring region ) / 2 - D (This

setting may be omitted.)

• Invalidation period : Generally set to 0 ms.

• Number of measurements: N = 1

NOTE • Allow a sufficient margin for the lower detection limit, upper detection limit, invali-

dation period, and number of measuring times when setting them. If this surplus is not sufficient, the measurement may not be achieved.

• If using the sample measurement, specify the number of measuring times to 1.

• The automatic workpiece detection functions in the continuous-run measurement.

• In the basic setup select whether group judgment is to be performed. If it is, then set the group size (the number of workpieces included in a group), calculation items (mean, maximum value, minimum value, and range), and group lower limit and upper limit. If “Not performing group judgment” is selected, the setup guidance for it will not be displayed.

2. If the second Analog I/O Interface is used Each individual judgment result will be outputted for A-(+NG), A-(GO), and A-(NG), and the group judgment result will be outputted for B-(+NG), B-(GO), and B-(NG), respectively.

In the basic setup it is possible to set whether the group judgment result data is outputted for the RS-232C/GP-IB interface. If it is, the output contents from the group judgment will be as follows:

• Each individual piece of measurement data can be the objective of statistical processing, however, group measurement data will be excluded from statistical processing.

• Even if “Err-0” (specified workpiece not present) occurs, the obtained data will not be cleared. To abort the measurement, press the

key (or input RESET via the I/O

Interface or the “CL” command via the RS-232C/GP-IB interface).

3.2.17 Recording the amount of light

• The gap measurement may be unstable if not enough laser beam passes through the gaps. In the case shown in diagram (a) below, an adequate amount of light can be obtained as the laser passes through gap (g) above the workpiece, even if the gap (t) is small. However, in diagram (b) where gap (t) is small, measurement will be affected. In this case, therefore, it is necessary to have the system record the full amount of light when there is no obstruction (workpiece or fixture) in the optical path.

Laser beam passes through this gap.

(a) Light amount can be detected normally = Auto-detecting

(b) Recording the amount of light is required

• Normally the amount of incident light is continuously checked so that the counting operation can follow the change in the amount of incident light. Have the system record the light amount following 4.4, “Recording the light amount”. It is also necessary to carry out this operation twice or three times each year since the light amount of the system may vary.

• If the amount of light is recorded, temperature drift of the measured data becomes larger.

• The minimum size of gap (t) that can be measured depends on each Measuring Unit as

3.4.2 Example key operations

As an example operation this section uses an update of the tolerance limits which are displayed in the upper display section while in the ready state. Suppose that the new lower tolerance limit is “12.34500” and the upper tolerance limit is “12.34600” and that the current values are “12.00000” and “12.00100”.

In the example below, we start with canceling existing upper and lower tolerance limits since the lower tolerance limit to be set is smaller than the existing upper tolerance limit. If this is the case, setting the lower tolerance limit first causes an error (ERR-5).

3. DISPLAYS AND KEY OPERATIONS

Step 1: In the ready state press the key to make

the setup item being displayed flash in the upper display section.

Each time the key is pressed, while the setup item is flashing, the setup item will change sequentially: Segment → Measurement interval → Lower limit value → Upper limit value → Reference value → Preset

→ Mastering →

If the key is pressed, the setup item will change in the reverse order. As the displayed setup items vary with the results of the basic setup, refer to Section

5.1.1, “Settings made in the measurement mode”

Step 2: If the upper limit value is going to be canceled,

make the guidance flash.

Step 3: Press either the

key: About the read operation

READ

Generally, in the calibration or offset value setup operation a reference gage is used, resulting in a measured data that is very close to the setup value. If this is the case, first read a measurement as the setup data, then correct the minor difference.

3. To enter a numeric value such as a gage diameter, it is more convenient to use the numeric keys. To correct a specific digit, it is more convenient to use the arrow keys.

4. To select a setup item such as the resolution in the basic setup, it is better to use the or key. Use of a numeric key causes an operation error.

SETTING UP THE

4.1 Basic Setup

HIGH CAL gages vary in shape depending on the LSM model to be calibrated. Set the calibration gage so that the calibration guide line ( | ) on the side face of the calibration gage comes vertical, and so that the center of the calibrated section is measured.

Step 1: Cancel the previously set calibration values.

It is not necessary if this setup operation is made with the previously used calibration gage. However, if the new gage diameter is much different from that of the previous one, an error (Err-2) may result. If this is the case, cancel the LOW CAL calibration value, then begin with the setting of HIGH CAL value (it does not matter if both the LOW CAL and HIGH CAL values are canceled).

IMPORTANT Calibration

1. Before performing a calibration, always perform the necessary setup for the resolution and dual-unit measurement. If this order is reversed, the set calibration value may be canceled and the measurement accuracy is not guaranteed.

2. Canceling the HIGH CAL value will also cancel the LOW CAL, offset, and mastering values.

3. With only a LOW CAL setup value the compensation calculation does not take place. This calculation will start when a HIGH CAL (or HIGH CAL and LOW CAL) value is set. If a HIGH CAL value is set, the CAL guidance ( ) will turn on in the display unit.

4. A calibration gage is important in that it is critical to the accuracy of the Measuring Unit. Wipe dust and oil from the gage with a cloth soaked in alcohol or thinner before using it. After use, apply a rust preventive oil to its surfaces and store it carefully in a dedicated case.

5. To confirm the HIGH CAL or LOW CAL setup value, press either the

key to enter each setup mode, and press the

6. On the user-supplied calibration gages, the dimensional ratio of a High CAL gage to a Low CAL gage should be greater than 1.2. Calibration performed with the calibration gages with diameters that are too close each other may reduce the measuring accuracy. The calibration gage should be the one which is made of the same or similar material as that of the workpiece. If a calibration gage of different material is used, error may be involved in measurement due to the difference in surface textures or properties.

7. For calibration measurement, no restriction exist for segment specification. If a gap or displacement needs to be precisely measured, a thickness gage can be used for calibration.
