Surface roughness measurement tool TR200- precision roughness symbol

Surface roughness measurement tool TR200- precision finish symbol measuring principle: The instrument measuring the surface roughness, the first sensor to take on the measured surface of the workpiece, and then start measuring instruments, driven by a precision drive mechanism inside the instrument measured surface sensors do uniform linear slide sensor measured surface roughness feel through the built-sharp stylus roughness of the workpiece surface to be measured at this time will cause the stylus displacement, the displacement sensor inductance coil inductance changes, resulting in the measured surface roughness is proportional to an analog signal at the output of the phase sensitive detector, the signal after amplification and level conversion into the data acquisition system, DSP chip for data acquisition and digital filtering wave parameter calculation, measurement results are given on the LCD monitor can also be output on the printer, you can communicate with the PC. Host parameters: measurement parameters (μm) Rq, Rt, Rp, Rv, R3z, R3y, RzJIS, Rsk, Rku, Rsm, Rmr the measuring range (μm) Ra (0.005μm ~ 16μm), Rz (0.02μm ~ 160μm), sampling length (mm) 0.25mm, 0.8mm, 2.5mm, 8mm evaluation length (mm) (1-5) l Maximum driving stroke 17.5mm / 0.7inch stroke length (mm) 6mm indication accuracy 0.001 indication error ± (7 -10)% indication variability <6% of the measured profile roughness, waviness, original contour filter RC, PCRC, Gauss, ISO13565 internal storage capacity of 100 sets of raw data from external input / output interface USB power supply built-in lithium ion rechargeable battery / external power adapter Dimensions 140 * 53 * 40mm Weight about 0.6Kg (host) surface roughness tester roughness TR200- precision tools ROUTINE MAINTENANCE: 1. Complete the sensor measurements, please sensors into the box; 2. Always take care to protect the stylus sensor part II, Host 1. keep clean the host surface, often with a soft, dry cloth to remove dust on its surface; 2. The instrument of precision measuring instruments , should always be kept gently, avoid subject it to vibration. Third, the battery 1. Regular observation battery prompt, when there is a low voltage, please charge; 2. The charge time is about three hours, try not to charge a long time. Fourth, the calibration model 1 model surface to keep clean; avoid scratching the surface of the model work area. Surface roughness measurement tool TR200- precision finish symbol Common symptoms of error messages and Symptom Cause Remedy measured surface out of range or beyond the measuring range of the instrument away from the center position of the stylus transform large range adjustment of the stylus position without test data boot After no measurements are actually measuring a motor motor running problem walking dead remeasure runtime error abort reboot
