1. System Function Description and Technical Specifications

1.1Characteristics and advantages description

model:FM-310Type（8Gear load)

Load:A：10,25,50,100,200,300,500,1000gf (The direct loading method of the top weight of the vertical guide rail can provide higher precision loads, especially for small loads)

1） Compliant with the countryGBInternationalISOThe United StatesASTMAnd JapanJISStandards, with a wide range of compliance, facilitate comparison of measurement results under different standards;

2） Measurable parametersHV、HKWide range of use;

3） pickVertical loading method using the top weight of the pressure headThe stability and accuracy of the test load are high, especially100gfThe following loads meet the testing and research requirements for material microstructure phases;

F≥200gfTolerance ±0.5%；5gf≤F<200gfTolerance ±0.8%（FTo test the loadF-TFactory standard)

（ISOreachGBstandard F≥200gf Tolerance ±1%；10gf≤F<200gf Tolerance ±1.5%）

4） Loading speed increase5-120μm/secAdjustable, choosing a low loading speed can avoid errors caused by high-speed loading impacts during testing of extremely thin and soft metal (non-ferrous metal) samples;

5） The revolving tower can be equipped with both4Set different magnification objective lenses (standard configuration)10,50Double) and2Set different pressure heads (standard configuration)HV,Optional dual head towerHV/HK）It is possible to perform a wide range of sample contour scanning with low magnification or convert to high magnification for hardness measurement as needed,Good elasticity and high efficiency in use;

6） Subject andThe automatic lifting structure of the workbenchCThe type design ensures that the loading mechanism is relatively fixed to the entire frame, with good rigidity, simple maintenance, and long service life;

7） Eyepiece measurement using high-resolution rotary encoder（250Line), eyepiece measurement * small resolution unit0.01µm（ISOreachGBThe standard is0.2µm）；

d≤40µm *Great tolerance difference ±0.08µm；d>40µm *Great tolerance difference ±0.3%d（dFor diagonal lengthF-TFactory standard)

（ISOreachGBstandardd≤40µm *Great tolerance difference±0.4µm ；d>40µm *Great tolerance difference ±1.0%d）

8） useLEDCold light source, long lifespan, good lighting effect. Color filters can be used interchangeably, and the aperture and field of view light bars can be adjusted. The design, similar to a metallographic microscope, fully meets the observation of the metallographic structure of special samples;
