FEATURES:
1. THE EQUIPMENT IS COMPOSED OF A SEMI-ARC BOW, RECORDING DEVICE, SEAT FRAME AND TEST HEAD DIE.
2. SEMI-ARC BOW: THE RADIUS IS 300 TO 340 mm
CAN BE ROTATED AROUND THE HORIZONTAL RADIUS PLANE PASSING THROUGH THE POINT 0°, AND A SCALE EXTENDING TO THE 90° ARC BOW EVERY 5° FROM 0° ON BOTH SIDES, EQUIPPED WITH SLIDING WHITE VISUAL STANDARD.
3. RECORDING DEVICE: THE RECORDING NEEDLE IS CONNECTED WITH THE VISUAL STANDARD THROUGH COMPONENTS SUCH AS AXLE WHEEL, AND THE DIRECTION AND ANGLE OF THE VISUAL STANDARD ARE RECORDED ON THE VISUAL FIELD DRAWING CORRESPONDINGLY.
4. SEAT FRAME: USED TO SUPPORT SEMI-CIRCULAR ARC BOW AND FIXED RECORDING DEVICE.
5. TEST THE HEAD MOLD: A STANDARD HEAD MOLD, THE TWO EYE HOLES OF THE HEAD MOLD ARE EQUIPPED WITH SMALL LIGHT BULBS, THE POSITION OF THE BULB AND THE POSITION OF THE HEAD MOLD ARE ACCORDING TO THE REQUIREMENTS OF GB 2890. THE TEST HEAD DIE MUST BE INSTALLED ON THE WORKBENCH IN SUCH A WAY THAT THE LEFT AND RIGHT EYES ARE PLACED AT THE CENTER OF THE SEMICIRCULAR ARCH AND THE "0" POINT IS DIRECTLY SEEN.

MAIN INDICATORS
1. SEMI-CIRCULAR ARC RADIUS: 335mm.
