Best Management Practice for Perchlorate Materials – California only

■

When you sell, manufacture and/or waste the products containing perchlorate material in California, the following statement must appear on the exterior of all outer shipping packages and on consumer packages, based on California Code of Regulations.

“Perchlorate Material – special handling may apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate.”

Note: Alternative option is to indicate this statement on your MSDS or manual accompanying with each product.

This product includes a CR coin type cell containing perchlorate material. If you ship this product (or your product including this product) to California, you must ensure to comply with this regulation.

Page 5

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-7600 Series to be uniform.

■ Warming Up

Do not operate the LS-7600 Series for approximately 30 minutes after it is turned on. The internal circuitry of the LS-7600 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 surface 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-7600 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-7600 Series with a damp cloth or a cloth moistened with benzine or paint thinner. This may cause the discoloration or deformation of the LS-7600 Series. If the LS7600 Series is excessively dirty, use a tightly squeezed cloth moistened with thin neutral detergent. Then wipe the LS-7600 Series with a soft dry cloth.

■ Precautions for LED

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

CAUTION

• Do not look at the LED light source for a long time. 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.

■ 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.

Area Settings

Area settings are used to determine the measurements taken from a variety of objects placed in the beam. The LS-7600 Series can use up to two measuring heads to set two measurements (AREA1 and AREA2) for simultaneous measurements.

Area Settings

Area settings include the following items.

• Area: Select the measuring head number together with the DIA, T-EDGE, B-EDGE, or SEG mode.

• Area display: Turn the cursor on the target viewer ON or OFF.

• Focus monitor: A function to check whether the target is within the measuring range. Set the best measuring range (i.e., the distance between the target and transmitter) with this function.

• Area check: Set the total number of edges to be measured. If the number of edges detected does not coincide with the set value, the measured value will be invalidated.

• Difference check: If there is a radical change between measured values, the change will be detected and output. Set the value for the change to be detected.

• Function output selection: Set the items to be output from the output terminal on the rear panel.

• Edge detection threshold change: Set the threshold to be detected when measuring highly transparent objects.

Area Setting Procedure

Make area settings while checking the display on the LCD monitor. The following procedure is for area settings through the remote control console.

1 Set the [Slide Switch] key to PROG. 2 Press the [Up or Down] key to move

the cursor to the AREA.

Area Selection

Area

When a target is located in the measuring area as shown below, the light into the receiver is partly obstructed, thus creating a shadow. The contour of the shadow is called “edge.” The area is surrounded by the edge line. The LS-7600 Series can measure objects with area designation or edge designation. Area designation is possible in DIA, T-EDGE, or B-EDGE mode. Edge designation is possible in SEG mode.

■ DIA (Diameter)

When the LS-7600 Series is in DIA measurement operation, it measures the outer diameters of round bars or transparent

objects. The area between the top of the first shadow and the bottom of the last shadow is measured as shown in the illustrations.

■ SEG (Segment)

Select this setting for the measurement of the inner diameters of discs or the measurement of pitches. The edge where the measurement of the object in the measuring area starts is called “start edge” and the edge where the measurement terminates is called a “end edge.” The space between these edges specified is measured. Segment measurement is performed in E mode or P mode. If objects are measured with the virtual center of the light axis set, use edge 0.

Setting Range

• Edge or pitch numbers can be designated between –127 and 127.

• The duplicated designation of an edge or pitch number will set the measured value to

• If edges or pitches are designated in reverse order, negative measured values will be

obtained.
