b: Turn the bottom corner adjustment screw, look at the leveler to center the bubble, and make the four soles solidly contact the rubber sheet.
c: Place the accessory box that came with the instrument next to it for backup.
★试验步骤：
a:测试人员必须按相关试验方法标准取样，使试样处在符合方法标准要求的测试状态。
b:右手握住凸轮手柄逆时针转动，使凸轮顶起压板和挂在压板右边的加压砝码全部重量。
c:取出压板下的可换压脚，根据测试样品厚度选择压脚型号。
0.5号适应测试土工膜、
5号适应测试0.5~5mm:厚度范围的土工布合成材料、
10号适应测试5~10mm:厚度范围的土工布合成材料、
15号适应测试10~12mm:厚度范围的土工布合成材料。
d:选好了可换压脚，用纯净的软布擦净基准板和压脚面，重新将压脚放到基准板上。注意压脚上的三角刀刃要对准压板下的倒置V型槽。
f:选标与安装：测量土工布选取百分表。（测量土工膜选取千分表，注：千分表自配）。将其插在表架孔中，表上触头碰到可换压脚上端面的时候，稍微往下移动0.1~0.2mm距离，螺旋锁紧螺母。然后将其表清零（或校零）。
g:轻轻提起可换压脚，将试样自然平放的插进基准板与压脚之间。放下压脚，使试样受到压力为2kPa正负0.01kPa ，同时安秒表计时，使试样受压时间30s时，读取百分表（或千分表）数值。
h:重复上述操作，完成规定的试样测试件数。
★Test steps:
a: The tester must sample according to the relevant test method standards, so that the sample is in the test state that meets the requirements of the method standard.
b: The right hａnd holds the cam handle to rotate counterclockwise, so that the cam pushes up the weight of the pressure plate and the pressing weight hanging on the right side of the pressure plate.
c: Remove the replaceable presser foot under the pressure plate and select the presser foot type according to the thickness of the test sample.
No. 0.5 adapts to test geomembrane,
No. 5 adaptation test 0.5~5mm: geotextile composite material in thickness range,
10th Adaptation Test 5~10mm: Geotextile composite material with thickness range,
No. 15 adaptation test 10~12mm: geotextile composite material with thickness range.
d: Select the replaceable presser foot, clean the reference plate and presser foot surface with a clean soft cloth, and put the presser foot on the reference plate again. Note that the triangular blade on the presser foot is aligned with the inverted V-groove under the platen.
f: Selection and installation: measure the geotextile selection dialer. (Measure the geomembrane to select the dial gauge, note: the dial gauge is self-matching). Insert it into the hole of the watch frame. When the contact on the upper surface of the watch touches the upper end surface of the pressable presser foot, move it slightly downward by 0.1~0.2mm and screw the nut. Then clear its table (or zero).
g: Gently lift the replaceable presser foot and insert the sample naturally between the reference plate and the presser foot. Put down the presser foot, and let the sample be subjected to pressure of 2kPa plus or minus 0.01kPa, and the ammeter shall be timed to read the dial gauge (or dial gauge) when the sample is pressed for 30s.
h: Repeat the above operation to complete the specified number of test pieces.
★根据需要选用不同的测试压力：
a:试样在20kPa压力状态下测试，重复3.2.6步骤后，将加压砝码1挂在压板右边的挂圈上，然后用右手将凸轮手柄往顺时针方向转动。使加压的重量*由可换压脚的三角刀刃为支撑线时，同时按秒表计时，使试样受压时间30s时读取百分表（或千分表）数值。
b:试样在200Pa压力状态下测试，重复3.2.6:步骤后，将加压砝码1和加压砝码2同时挂在压板右边的挂圈上，然后用右手将凸轮手柄往顺时针方向转动，是加压的重量*由可换压脚的三角刀刃为支撑线时，同时按秒表计时，使试样受压时间30s时读取百分表（或千分表）数值。
★ Choose different test pressures as needed:
a: The test is tested under a pressure of 20 kPa. After repeating step 3.2.6, the pressurizing weight 1 is hung on the hanging ring on the right side of the press plate, and then the cam handle is rotated clockwise with the right hand. When the weight of the pressurization is completely supported by the triangular blade of the replaceable presser foot, the timepiece is timed, and the dial gauge (or dial gauge) value is read when the sample is pressed for 30 seconds.
b:The test is tested under a pressure of 200 Pa. Repeat 3.2.6: After the step, the press weight 1 and the press weight 2 are simultaneously hung on the hanging ring on the right side of the press plate, and then the cam handle is clockwise with the right hand. The direction of rotation is that when the weight of the pressurization is completely supported by the triangular blade of the replaceable presser foot, the stopwatch is used to time, and the value of the dial gauge (or dial gauge) is read when the sample is pressed for 30 seconds.
工工布厚度仪使用注意事项
★仪器必须安置在无化学腐蚀、远离振动源的工作室中，否则会影响测试结果。
★任何一只可换压脚都有自身规定重量与形状，并与其压板、压重砝码2:组合产生一组相关规定重量，在使用过程中要妥善保管，不得损坏几何形状或接触化学腐蚀品。
★仪器出厂时已经调节好调节砣与压力支点的关系，用户一般不得任意变动调节砣的位置关系，以免影响对试样的总压力。
★仪器在使用中，若出现测试精度严重偏差应请人员维修，以免作出虚假试验报告
Work cloth thickness meter use precautions
★ The instrument must be placed in a laboratory that is free of chemical corrosion and away from the vibration source, otherwise it will affect the test results.
★Each one can change the presser foot with its own specified weight and shape, and combine with its pressure plate and weight code 2: to produce a set of related weights, which should be properly kept during use, and must not damage the geometry or contact with chemical corrosion. Product.
★ The instrument has been adjusted to adjust the relationship between the pressure and the fulcrum. The user should not arbitrarily change the positional relationship of the 砣 to avoid affecting the total pressure of the sample.
★If the instrument is in use, if there is serious deviation of the test accuracy, please ask the professional to repair it, so as to avoid making false test report.
