［１］General

Surface Stress Meter FSM-6000LE is a device for measuring the surface compression stress , the depth of layer and the central tension stress of a tempered glasses by using optical waveguide effect in the surface layer of the glass.The meter, however, can not be applied to chemically tempered glass produced by (Li+ in glass) and (Na+ in salt bath) ion exchange and chemically tempered photochromic glass.

［２］Installation

Sets it up in a little dark place and in the place where the vibration is a little.

FSM-6000LEMeasurement head

［３］Connection

FSM-6000LE　Harsware Manual　p.１

Connect the cable of CCD camera to the USB socket of PC.

Connect the cable of One-touch switch (exclusive use with FsmⅡ Premium) to the USB socket of PC. And plug-in the AC adapter to outlet.

FSM-6000LE　Hardware Manual　p.2

(4) Start the PC up and start the FsmⅡ software. (refer the software manual)

It is not use the software without the dongle. Insert the dongle in the USB outlet.

(5) Drop a small amount of immersion liquids onto the prism. Put the sample glass on the prism with the immersion liquid between the sample and the prism. Use a small amount of immersion liquid as much as possible.It can not measure correctly by the dirt of liquid on the side of prism.

(6) Turn the lamp-height adjustment knob so that screen become brighter.

lamp-height is not good lamp-height is good

(7) Adjust the angle of telescope that the fringes appear in the center of the screen. Adjust contrast of the fringes with the brightness adjustment knob.

［４］Operation

(1) Insert the plug into a line source socket.(2) Turn the power switch on.(3) The lamp becomes enough bright.

The measurement prism

(9) The position of each device in which the interference fringes overlap might move up and down a little . At that time, adjust the area as follows (refer Software manual 5.3 Adjusting Measurement Area)

Overlapped position is out of the boundary area and the base area is on the right side fringes

Extend the boundary area and move the base area

(10) Measurment (refer the Software manual 5.7 Measurement Method)

(11) Wipe the surface of prism and turn the lamp off after measuring

［５］maintenance

(1) Wipe off the immersion liquid or dirt of the surface of the prism with a soft paper wiper. The interference fringe becomes indistinct when there are a lot of scratches in the surface of the prism. At that time, replace it with the new prism with the holder. ( it is not included )

Prism and prism holderRefractive index of the prism is 1.72

(3) Immersion liquid as the accessory is safe. Please use the liquid of safety and non-causticity when you use other liquids. (Transparent liquid of refractive index nd=1.64 or more)

［６］Attention

The object lens fixed to the top of the telescope. Do not move the lens. It is important for the magnification of the device.

③ Display of measurement error

o The error message is displayed and the measurement is interrupted when the inclination of the interference fringes and the spacing and the number are conditions other than the definition.

o Please measure it again after adjusting the angle of the camera or adjusting the source of light etc.

o The density of the interference fringes might be different according to the condition of strengthening.

o The ghost of the interference fringes might be generated and the array of the interference fringes are not theoretical.

o The image processing can be likely to be done automatically though PC might display the error message for attention.

o The measurement has ended normally when it can be confirmed to have selected the interference fringes correctly.

o Example displayed that fringes spacing is illegal.

o The interference fringes that appears in a bright area is normal.

o However, fringes like the interference fringes appear in a dark area though it is indistinct.

o In this case, it advances previously clicking "OK" button.

o All detected fringes are displayed in the green and majenta color lines.

o The majenta color lines are drawn in the dark area.

o All fringes that PC recognized are displayed.

o Two left green lines correspond two left fringes position.

o One of the right green line corresponds the boundary of a bright area and a dark area.

o This measurement is correctly done.

o The majenta color line is displayed to check "System setting" - "Setting Display" -"Disply fringe of non-

calculating" by “レ” mark.

o It can not measure stress and depth when the number of fringes are less than two.

o The depth of layer is less than five micron in this case, and it can not measure the surface stress.

o It can measure the outline value of the surface stress by manual measurement method.

o It sets the first line on the left end fringe.

o It sets the second line near left of the boundary .

o It sets the fourth line on the boundary.

o It enters two as the number of fringes.
