This resets all executing measurements and outputs. While a reset is
being input, judgment output conforms to the non-measurement setting. If this reset input switches ON while the hold function is used, the
state in effect before the hold function was set will be restored.
LD-OFF input
If this LD-OFF signal is set to ON, the laser will stop emission, causing
a light amount error. While LD-OFF is being input, judgment output
conforms to the non-measurement setting.

Multi-sensitivity processing functions to automatically sweep the amount of emitted light to obtain
the optimum amount of reflected light on each measurement plane. (The emitted light beam
appears to flicker.)For this reason, note that the measurement cycle increases to become longer
than during regular measurement. About 76 times more than regular measurement. In the standard mode, the measurement cycle is about 40ms.)
• When [STOP] is set, the upper limit of the auto range for the amount of emitted light is automatically changed to 20%.
• The measurement cycle can also be shortened by limiting the upper limit of the auto range for
the amount of emitted light.
• When measurement cannot be performed normally, adjust the upper and lower limits of the
auto range for the amount of emitted light.
• The mutual interface prevention function does not operate at this setting.
MOVE
Thickness and gap can be measured stably at high speed by dividing the measurement area into
separate sections for each plane to measure and adjusting the light intensity inside each range.
Teaching (measurement) is performed when the [THICK] or [GAP] setting is completed, and the
measurement area is automatically determined if measurement is possible.
• The set area can be confirmed in SmartMonitor Zero. Adjust the area to the optimum area
according to the detection state.
• The entire area is set if measurement was not possible during the setup.Use SmartMonitor

Setting Zero Reset
When the zero reset function is used, the reference value “0” is registered as the height
and the measured value can be displayed and output as a positive or negative deviation
(tolerance) from the reference value. In the RUN mode, the measured value can be reset
to 0 at any timing during measurement.

• When turning the power ON, if you want to keep the zero reset level data that was in effect when
the power was turned OFF last time, make sure that zero reset memory is enabled.If zero reset
memory is enabled, the zero reset level data will be written in the Sensor Controller non-volatile
memory (EEPROM) at each zero reset.The EEPROM can be written a maximum of 100,000
times. Writing the zero reset level for each measurement can, therefore, use up the life of the
memory and lead to malfunctions.
• Even if zero reset memory is enabled, the zero reset level will be held also when it is saved. Zero
reset will continue after startup when these functions have been changed.

Q&A
Question
When scaling is executed, an error appears and
settings cannot be made.
Answer
Scaling cannot be set for one of the following reasons:
• Scaling has been attempted when the measured value is
outside the measuring range.
• When two-point scaling has been executed, the distance
between the measured values for the two points is not 1%
or more of the rated measuring range.
p.3-20
When focusing is executed, an error appears and
settings cannot be made.
Monitor focus settings cannot be made when the distance
between the two specified points is not 1% or more of the
rated measuring range.

Glossary
Term
Measured value
Explanation
The measured value is the measurement result displayed on the main display of the Sensor Controller in the RUN and TEACH modes. It is the value when each of the currently set
functions (e.g. hold) has been processed.
p.3-7
Present value
The present value is the current measurement result for the target Sensor Controller.
It is the value before each of the currently set functions (e.g. hold) has been processed.
Press the LEFT or RIGHT Key in the RUN mode to display the present value on the subdisplay.
p.3-7
Section 6 APPENDIX
Linearity
The linearity is given as the error on an ideal straight line displacement output when measuring the standard sensing object. The linearity shows how closely the linear output maintains a linear relationship to the displacement of the sensing object (i.e., it shows the
accuracy of the linear output).
Linear output
The linear output is output from the linear output line. Either current or voltage output can
be selected.
The linear output is made based on the display value and focus settings.
The actual value output (the output value) can be displayed on the sub-display by pressing
the LEFT or RIGHT Key in RUN mode.
p.3-7
Judgment output
"Judgment output" is a general term for the HIGH, PASS, and LOW outputs. Judgment outputs are made in the RUN or TEACH mode based on the display values and the threshold,
hysteresis width, and timer settings.
SmartMonitor Zero This is software that runs on a personal computer.
This software enables communication with Sensor Controller, sets measurement conditions, saves setting data, and displays measurement results as a graph.

Class
Description
Class 1
Lasers which are safe under reasonably foreseeable conditions of operation.
Class 2
Lasers emitting visible radiation in the wavelength range from 400 nm to 700 nm. Eye protection is normally afforded by aversion responses including the blink reflex.
Class 3A
Lasers which are safe for viewing with the unaided eye. For laser emitting in the wavelength range from 400 nm to 700 nm, protection is afforded by aversion responses including the blink reflex. For other wavelengths the hazard to the unaided eye is no greater than
for Class 1. Direct intrabeam viewing of Class 3A lasers with optical aides (e.g., binoculars,
telescopes, microscopes) may be hazardous.
Class 3B
Direct intrabeam viewing of these lasers is always hazardous. Viewing diffuse reflections is
normally safe (see note).
Class 4
Lasers which are also capable of producing hazardous diffuse reflections. They may cause
skin injuries and could also constitute a fire hazard. Their use requires extreme caution.
Note: Conditions for safe viewing of diffuse reflections for Class 3B visible lasers are: minimum viewing distance of
13 cm between screen and cornea and a maximum viewing time of 10 s. Other viewing conditions require a
comparison of the diffuse reflection exposure with the MPE.

FDA definition
Class I/1
Limits applicable to devices that have emissions in the ultraviolet, visible, and infrared
spectra, and limits below which biological
hazards have not been established.
Class IIa/2a
Limits applicable to products whose visible
emission does not exceed Class I limits for
emission durations of 1,000 seconds or less
and are not intended for viewing.
Class II/2
ANSI description
A Class 1 laser is considered to be incapable of producing damaging radiation levels
during operation and maintenance and is,
therefore, exempt from any control measures or other forms of surveillance.
Class 2 lasers are divided into two subclasses, 2 and 2a. A Class 2 laser emits in

Class IIIa/3a
Limits to products that have emissions in the
visible spectrum and that have beams
where the total collectable radiant power
does not exceed 5 milliwatts.
Class IIIb/3b
Limits applicable to devices that emit in the
ultraviolet, visible, and infrared spectra.
Class IIIb products include laser systems
ranging from 5 to 500 milliwatts in the visible
spectrum. Class IIIb emission levels are
ocular hazards for direct exposure throughout the range of the Class, and skin hazards
at the higher levels of the Class.
Class 3 lasers are divided into two subclasses, 3a and 3b. A Class 3 laser may be
hazardous under direct and specular reflection viewing conditions, but the diffuse
reflection is usually not a hazard.
Class IV/4
Exceeding the limits of Class IIIb and are a
hazard for scattered reflection as well as for
direct exposure.

A Class 4 laser is a hazard to the eye or skin
from the direct beam and sometimes from a
diffuse reflection and also can be a fire hazard. Class 4 lasers may also produce lasergenerated air contaminants and hazardous
plasma radiation.
