CAUTION	■ Usage
	• Be sure to turn off the power to the LS-7000 Series and any
	connected devices before connecting or disconnecting the
	cables. Otherwise, the camera and connected devices may be
	damaged.

•Do not turn off the power while setting a parameter. Otherwise, the settings may be partially or completely lost.

•Do not block the ventilation slots on the LS-7000 Series and peripheral devices. A rise in inner temperature may cause equipment failure.

■ Proper environment and conditions

To use the LS-7000 Series properly and safely, do not install the LS-7000 Series in locations with the following conditions. Use of this equipment in an improper environment may cause fire, electric shock, or equipment failure.

•Locations with high humidity, a large amount of dust, or poor ventilation

•Locations where the temperature rises excessively due to direct sunlight, etc.

•Locations where corrosive or flammable gas exists

•Locations where the LS-7000 Series is directly subjected to vibration or impact

•Locations where water, oil or chemicals may splash the LS7000 Series

•Locations where static electricity is easily built up

■ Countermeasures against Noise

The LS-7000 Series may malfunction or fail to operate due to noise generated from power lines or high-tension lines. If the LS7000 Series is operated close to such noise sources, use a noise filter, wire the cable of the LS-7000 Series in an independent conduit, or locate the LS-7000 Series in an area with proper insulation from noise.

ii

Note:	■ Influence of Ambient Operating Temperature
	Ensure that the ambient operating temperature is constant. A
	change in the ambient operating temperature may result in
	measurement errors. If the ambient operating temperature
	changes by 10°C, it will take approximately 60 minutes for the
	interior temperature distribution of the LS-7000 Series to be
	uniform.
	■ Warming Up
	Do not operate the LS-7000 Series for approximately 30 minutes
	after it is turned on. The internal circuitry of the LS-7000 Series is
	not stable immediately after it is turned on. The measured value
	drifts gradually as a result.
	■ Influence of Dust and Dirt
	A measurement error may result due to dirt, dust, water, or oil in
	any of the following cases.
	• Cover glass: Blow off the dirt, dust, water or oil on the cover
		glass with clean air. If the cover glass is excessively dirty, wipe
		the glass with a soft cloth moistened with isopropyl alcohol.
	•	Target surface: Blow off the dirt, dust, water or oil on the sur-
		face with clean air or wipe the surface.
	•	Intrusion of dirt, dust, water or oil blown or sprayed into optical
		sensing area: Install a protection cover or perform air purging.

■ Influence of Vibration

The measured value of an object may fluctuate if the object is vibrating. If that happens, increase the averaging number. This will ensure highly accurate measurement.

■ Targets

The measured value of an object may have an error due to the shape and surface condition. Locate a reference object within the measuring area and use the calibration function of the LS-7000 Series to correct the error if that happens.

■ Influence of Air Flow

The measured value of an object may fluctuate due to a slow flow of air. In that case, the following countermeasures are effective.

• Protect the measuring head with a cover.

• Use a fan to mix the air vigorously between the transmitter and receiver.

■ Maintenance

Do not wipe the LS-7000 Series with a damp cloth or a cloth moistened with benzine or paint thinner. This may cause the discoloration or deformation of the LS-7000 Series. If the LS7000 Series is excessively dirty, use a tightly squeezed cloth moistened with thin neutral detergent. Then wipe the LS-7000 Series with a soft dry cloth.

■ Precautions for LED

The LS-7010/LS-7030/LS-7070 Measuring Head uses an LED light source. Abide by the following precautions when using the unit.

	• Do not look at the LED light source for a long time.
CAUTION
	The LED used as the light source is classified into class 1
	according to IEC60825-1 standards. Basically the light beam of
	the LED is safe, but do not look at the LED for a long time.
	• Do not disassemble the unit.
	The unit does not incorporate a mechanism to stop the emission
	of the LED when the unit is disassembled. Never attempt to
	disassemble the unit, otherwise you will be exposed to LED light.	iii

Chapter 1 Getting Started

Outline and Features of LS-7000 Series

The LS-7000 Series is a high-speed, high-accuracy digital micrometer used for the dimen- 1 sional measurement of objects without coming into contact with the objects. It is such a

versatile model that it has a wide range of applications including in-line measurement and offline measurement.

■ Special Features

High-speed Sampling of 2400 Times per Second

Ensures high-speed sampling that is twice as fast as the sampling speed of conventional models. The continuous measurement of extruded products and the in-line measurement of moving workpieces are possible.

Repeat Accuracy of ±0.15μm

Incorporates the latest optical system, thus ensuring excellent repeat accuracy that is twice as high as the accuracy of conventional models, thus supporting the manufacture of high-precision products.

Connecting Two Measuring Heads for two-channel Simultaneous Measurement

Two measuring heads can be used in combination for the simultaneous measurement of two targets.

Stable Detection of Transparent Objects with Threshold Change

The threshold change function supported by the DE processor makes it possible to detect transparent objects stably.

■ Principle of Measurement

The high-intensity GaN green LED radiates light, which will be changed into uniform parallel light through the special diffusion unit and collimator lens and emitted to the target in the measuring range. Then the shadow image of the target will appear on the HL-CCD (high-speed linear CCD) through the telecentric optical system. The output incident signal of the HL-CCD will be processed by the DE (digital edge-detection) processor in the controller and CPU. As a result, the dimensions of the target will be displayed and output.
