Y511B Fabric pick glass
Used to determine the number of warp or weft yarn length within various Fabric.
magnification:
Fabric Fabric 10 times for the following 60
20 times for 60 or more fabric Fabric
Ruler moving range: 0-50mm Outline size: 97 * 53 * 35mm
Instructions
1, according to the measured Fabric count, selected magnification lens, then head mounted on the frame of the instrument.
2. The Fabric of color, determine the selection of a color cursor proportion engraved lines, choose three colors in the same color swap, easy to test count.
3, operation and determination, the instrument placed on the analyte, should and Fabric warp, weft approximately parallel, adjusting the lens height so that was the clearest vision imaging state, lift the left hand side of the top of live instruments, the right hand rotating adjustment screw New York, so that the alignment groove to zero within the lens, then reverse adjustment knob, visual count warp, weft root of the number, namely Fabric density.
·maintenance
• Keep equipment clean appearance, lens blur, the application wipe lens paper wipe,
· Second, only the tip of the bottom surface, insert Fabric, keeping sharp, should be placed on a hard flat object.
use correctly
After the fabric pave the magnifying glass to adjust to the most clear where after adjustable pick glass scale to the zero position, determine a starting point (for example, starting from the center of the two yarn, or a yarn from the center), slowly Mobile, the number during the move, note the vertical direction yarn, to 1 inch line to stop (and sometimes not necessarily just an integer, for example, it is estimated that half of the root), then the density readings of the direction of X / inch, then turn cloth 90, as described above, then the operation.
In order to ensure more accurate readings, the readings are generally taken in the best part of 10 cm or less near hem, a direction to take at least three points, taking the average value, broadcloth to take five points. Sometimes encounter some fabrics with pick glass hard to look at it.
Some adopt cm and read density, anyway, it is Unit conversion problem, this is not difficult.
