1.6 Connection of sensor and main unit main body protective tube sensor socket main body protective tube Installation and Removing of sensor For installation, hold the main body of sensor with hand, push it into connection adapter at the bottom of the instrument as shown in Figure and then slightly pushed it to the end of the sheath. To remove, hold the main body of pickup or the root of protective sheath with hand and slowly pull it out.
2 Measuring Operation 2.1 Preparation for Measurement Switch-on to check if battery voltage is normal; Clear the surface of part to be measured; Place the instrument correctly, stably and reliably on the surface to be measured; Trace of the pickup must be vertical to the direction of process line of the measured surface. : Correct and standard operation is the premise for accurate measurement result, please make sure to follow it.
2.3 Stylus Position First, use the stylus position to determine the location of the sensor. The stylus as measured in the middle position. In the main interface mode, press the stylus position key switches stylus position display screen and the main display screen. 2.4 Start measurement In the main interface mode, press the Start button to start measuring Motor Detect...

2.7 Storage measurement results In the main display interface mode, press the key to save the measurement results stored in the instrument memory. Instrument built-in large capacity memory, can store 100 groups of raw data and waveform data. Data storage recording date and time the file name automatically generated according to the last data record is always stored the most recent recording time, the last data record stored recording record number will be 001.

2.12 Parameter calibration Before measuring instrument, usually required Menu calibration use standard calibration Block. The 4.Calibrate 5.Print instrument configured with standard 6.About calibration block, before measurement, Calibrate instruments to test the block. Under normal Ra= 1.51μm circumstances, when the measured value and the block value of the difference in the acceptable Calibrate range, the measurement value is valid, can be...

3 Options and Usage 3.1 Adjustable support When measured surface of part is smaller than the bottom surface of the instrument, sheath of pickup and adjustable supporter of instrument options can be used for auxiliary support to complete the measurement (as shown in Figure). Adjustable Support 1.the value L above shall not be shorter than driving stroke of this measurement to prevent...
3.2 Measurement Stand Measurement Stand can adjust the positions between tester and measured part conveniently with flexible and stable operation and wider application range. Roughness of complex shapes can also be measured. Measurement stand enable the adjustment of the position of stylus to be more precise and measurement to be more stable.
Protective Tube Main Body Socket Stylus Skid 3.5 Curved Surface Sensor Curved surface sensor is mainly used for measuring radius is larger than the smooth cylindrical 3mm surface roughness, for the larger radius smooth spherical surface and other surface also can obtain good approximation, the radius of curvature, the surface is smooth, the better the effect of measurement.

3.6 Pinhole sensor Using Pinhole pickup, the inner surfaces of holes with radius more than 2mm can be measured. Refer to the following Figure for detailed dimension. Pinhole pickup Deep Groove Sensor With deep groove sensor, it is possible to measure groove with width wider than 3mm and depth deeper than 10mm, or the surface roughness of step with height less than 10mm, Also can used to measure the planar, cylindrical used with platform.

Any time swap sensors are to be especially careful, careful not to touch the guide head and a stylus, because this is a key part of the whole instrument, to try to hold the sensor guide head bracket roots (the front of the body) plug.
5.4 Standard Sample Plate 1. The surface of a standard sample plate must be kept clean. 2. To avoid scratches on the surface of sample area. 5.5 Troubleshooting When the tester breaks down, handle the troubles according to measures described on Fault Information. If troubles still exist, please return the instrument to factory for repair.
Profile method —— Term, definitions and surface texture parameters." 6.1.1 Terms Filtered profile: profile signal after primary profile is filtered to remove waviness. D-P (direct-profile): adopt central line of Least Square Algorithm. RC filter: analogue 2RC filter with phase difference. PC-RC filter: RC filter with phase-correction.
Traversing length Origin 6.2 Parameters Definitions 6.2.1 Arithmetical Mean Deviation of Profile Ra Ra is arithmetic mean of the absolute values of profile deviation Z(x)from mean within sampling length. ∫ 6.2.2 Root-mean-square Deviation of Profile Rq Rq is the square root of the arithmetic mean of the squares of profile deviation Z(x) from mean within sampling length.
