Mounting the Sensor Head

In order to accurately measure a target, mount the sensor head so that the top surface of the target enters the measurement range.

MEASURING A SPECULAR TARGET

When measuring specular targets like glass or mirrors, mount the sensor head at an angle so that reflected laser light returns to the
receiver. When using the LK-H08x or the LK-H15x, use the LK-F3 or LK-F2 neutral density filter.

What is LK-Navigator 2?

LK-Navigator 2 is a software package that can be used to set up the LK-G5000 and acquire measurement values.

Launching LK-Navigator 2

Connect the sensor head to the controller and turn on the power. Prepare the PC that has had LK-Navigator (LK-H2) installed on it

and then connect the controller to the PC via USB cable.

Double click the LK-Navigator 2 icon to launch LK-Navigator 2.

Setup using LK-Navigator 2 (LK-H2)

This section will cover basic setup using LK-Navigator 2.

Sending settings

Once the button for “Send settings to controller” is clicked, the settings that have been created in LK-Navigator 2 will be applied

to the controller.

Receiving settings

Once the button for “Receive settings from controller” is clicked, the controller settings will be downloaded to LK-Navigator 2.

This is useful when checking the settings that are currently being used.

Displaying measurement values

Using LK-Navigator 2, it is possible to check the current measurement values. Once the “View Measurement Value” button has

been clicked, the Measurement Value Display window will appear.

Once the button for “Measurement value acquisition start” in this window is clicked, it will be possible to check the measurement

values.

Once the window is opened, the "Measurement

Value Display" screen will be on standby. By

clicking the "Measurement value acquisition start”

button, it will be possible to acquire measurement

values from the controller. By clicking the "Select

Display" button, it will be possible to select the OUT

number that will be displayed in the Measurement

Value Display window.

Sensor head-related settings

This section covers basic head level processing settings.

Head settings

This section controls head level target optimisation processes. This makes it possible to select measurement modes that are

optimised for specific target surface conditions and materials, and allows for corrections to compensate for sensor head mounting.

Measurement mode

Selects settings that have been optimised for various target surfaces.

Standard mode

The measurement mode that has been set as default and is optimal for the vast majority of diffuse targets. Measurement is normally

performed in this mode.

Translucent object mode

Used when measuring target that scatter light such as translucent resin.

Transparent object mode

Used when performing displacement or thickness measurement for transparent objects like glass or transparent films.

Used when the reflectivity of the different surfaces of a transparent object are the same.

6

Transparent object 2 mode

Used when measuring transparent object target that have multiple surfaces that differ in

reflectivity such as when measuring metal-deposited glass.

Semi-opaque object mode

Used when measuring diffuse targets with strong surface luster.

Mounting mode

Selects settings in response to the mounting method for the sensor head.

“Diffuse reflection”

As listed in P.2 of this guide, this setting is used when

the sensor head is mounted perpendicular to the target.

“Specular reflection mounting”

A method where the sensor head is mounted at an

angle to the target. By performing specular reflection

mounting, measurement is possible after correcting

physical errors caused by the angle.

OUT settings

OUT settings

These settings related to measurement value processing.

With the LK-G5000, measurement values can be calculated and displayed for each OUT. At default, the number of used OUTs is 2,

and up to 12 can be set. The number of used OUTs can be set in the environment settings.

*Once the “No. of used OUT” is changed, all programs will be initialised. The number of used OUTs must be the first thing to be set.

Calculation method

Sets which sensor head will display measurement values to which OUT and performs calculations between these measurement

values.

With the settings listed above, measurement values that have been measured with head 01 will be displayed at OUT1.
