This instrument is compatible with four standards of ISO, DIN, ANSI and JIS and is widely used in production site to measure surface roughness of various machinery-processed parts, calculate corresponding parameters according to selected measuring condition sand clearly display all measurement parameters. When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism inside the tester. The sensor gets the surface roughness by the sharp built-in probe. This roughness causes displacement of the probe which results in change of inductive amount of induction coils so as to generate analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier. The exclusive DSP processes and calculates and then outputs the measurement results on LCD. 2．SPECIFICATIONS Display： 4 digits, 10 mm LCD, with blue backlight Parameters: Ra, Rz Display Range Ra:   0.05-10.00um/1.000-400.0uinch  Rz:   0.020-100.0um/0.780-4000uinch Accuracy: Not more than 10% Fluctuation of display value: Not more than 6% Sensor: Test Principle: Inductance type       Radius of Probe Pin: 10um Material of Probe Pin: Diamond    Measurement Force of Probe: 16mN(1.6gf) Probe Angle: 90°                Vertical Radius of Guiding Head: 48mm Maximum driving stroke: 17.5mm/0.7inch Cutoff length (l): 0.25mm /0.8mm /2.5mm  optional Evaluation length: 1~5 cut off  optional Resolution : 0.001μm   if reading ＜10μm 0.01μm   if 10μm≤reading＜100μm 0.1μm   if reading ≥100μm Power Li-ion battery: rechargeable Attachment: Standard Sensor RP-100            Groove Stylus SRP-110      curvature Probe SRP-120 Extension Rod  SER-150          Measurement Stand   SRS-1    Bluetooth interface Standard Sample Plate   SSP-180       Cable and Software for RS-232/USB
