Production environment and moving a handheld instrument for measuring needs.

This instrument uses the needles trace method for measuring surface roughness
Measurement of workpiece surface roughness, first put the sensor being measured on the surface of the workpiece and start measuring instruments, instrument precision drive mechanism inside sensors along the surface speed taxi straight ahead and sensor with built-in sharp stylus to feel the roughness of the surface being measured. Measuring surface roughness of workpiece may cause stylus displacement, the displacement of the sensor inductor coil inductance changes, resulting in PSD output and analog signal proportional to the measured surface roughness. The signal is amplified and level conversion and enters the data acquisition system, ARM chips for digital filtering of the data collection and calculation, measurement results are given in the OLED display. Can connect through a wireless Bluetooth printer, print all measured parameters, you can also communicate with the PC through data cable, computer software for data for further analysis.

Handheld measurement
After plug sensor into instrument, measure directly on the workpiece surface. In addition to setting the correct measurement conditions, should also pay attention to:
A ... principal and level sensor
B. sensor slide direction perpendicular to the workpiece processing of texture.
Use a height gauge pillar
A. standard sensor be careful inserting instrument, and then installed on the connecting parts of the column, confirm lock;
B ... raised column of slide, slightly higher than the workpiece surface location to drop until the sensor contacts the workpiece, this process with caution, especially if the sensor contacts the workpiece be careful;
C ... sensor main body transferred to the Visual level to observe whether the stylus position close to the Centre;
D. lifting the sensor, be sure to pay attention to the direction, falling errors can damage the sensor.
Indication of calibration
① measuring reticle model;
② read Ra value;
③ compare with the model. Matters needing attention
1. any time, plug the sensor caution, be careful not to hit the head and PIN, which is a key part of the whole apparatus to try to hold the sensor head root of Bay (front)-plug
2. When you are finished using the sensor, please put it in a box

Abnormal when the instrument, please first read the failure index table, troubleshoot common problems, as a result of not measuring, liquid crystal display exception error too large, keyboard malfunctioning or failure such as confusion, please do not arbitrarily remove or adjust any fixed assembled components should be directed to the company's after-sale service Department for maintenance and processing.
