Introduction
The instrument adopts the principle of leverage to amplify the length of the pressure arm. Under the limited space and limited weight quality conditions, the thickness of the sample is tested under the pressure conditions of 2 kPa, 20 kPa and 200 kPa. The instrument is simple in structure, elegant in appearance and easy to operate. It is the first choice for the production and verification of geotextile and geomembrane thickness. This instrument is suitable for GB/T13761

[Installation and test methods]:
1. Instrument installation:
1.1 Unpack the instrument, clean the packaged wood chips and other dust particles with a clean soft cloth, place it on the work surface at the appropriate height, and place a soft and moderate rubber plate under each corner.
1.2 Rotate the bottom corner adjustment screw, watch the leveler to center the bubble, and make the four soles touch the rubber plate in a solid manner.
1.3 Place the accessory box attached to the instrument next to it for backup.
2 test steps:
2.1 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.
2.2 The right hand holds the cam handle to rotate counterclockwise, so that the cam pushes up the pressure plate and the weight of the pressing weight hanging on the right side of the pressure plate.
2.3 Remove the replaceable presser foot under the pressure plate and select the presser foot type according to the thickness of the test sample.

2.4 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 should be aligned with the inverted under the pressure plate.

Type groove.
2.5 Selection and installation: Measure the dial gauge of geotextile selection. (Measure the geomembrane to select the dial gauge, note: the dial gauge is self-matching). Insert it into the hole of the watch frame, and move it slightly downward when the contact on the upper surface of the watch touches the upper end surface of the presser foot.

Hang on the hanging ring on the right side of the platen, then use your right hand to turn the cam handle clockwise. When the weight of the pressurization is completely supported by the triangular blade of the replaceable presser foot, the time is measured by the stopwatch, and the sample is pressed.

At the same time, it is hung on the hanging ring on the right side of the pressure plate, and then the right hand is used to rotate the cam handle clockwise. When the weight of the press is completely supported by the triangular blade of the pressable foot, the meter is timed to make the sample receive Pressure time
30s
Read the dial indicator (or dial gauge) value.
3.4 Each test result must be manually recorded and calculated. The test results and test reports are based on the test method standard requirements and the production process requirements.

[Precautions for use]:
1 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.
2 Any one of the replaceable pressers has its own specified weight and shape, and its pressure plate and weight weight
2
The combination produces a set of relevant specified weights that should be kept in a safe place during use and must not damage the geometry or contact with chemical corrosion.
3 When the instrument is shipped from the factory, the relationship between the adjustment ç £ and the pressure fulcrum has been adjusted. The user should not arbitrarily change the positional relationship of the adjustment , to avoid affecting the total pressure of the sample.
4 In the use of the instrument, if there is a serious deviation of the test accuracy, please ask the professional to repair.
