Principle
The Roughness Gauge uses a Displacement Differential Inductance Sensor for measurement. The Sensor stylus is a natural diamond, with a 90 taper angle and a 5 μm tip radius, and touches the workpiece surface with a force measurement of 4 mN. The instrument uses a DSP chip for control and data processing. According to the selected sampling length and filter type, the Sensor is driven to move at different speeds, the surface profile data is collected, and asperity parameters and graphics are calculated and displayed.
Steps
1. Choose the right Sensors and Accessories for your measurement needs
2. Turn it on and check the battery level, and charge it if necessary.
3. Measurement parameters and conditions, including sampling length, evaluation length, filter type, etc
4. Place the Sensor on the surface of the workpiece to be tested correctly
5. Start measurement, the instrument automatically collects data
6. Measurement parameters and profile graphics displayed on the monitor
7. Optionally store data or print results via Bluetooth connection
8. Shut down in time after the measurement is completed or let the instrument automatically enter the sleep mode
Notice
• Make sure the instrument has sufficient power before measurement and avoid using it in a low power state
• Select the appropriate Sensor type to adapt to different surface shapes, such as plane, outer circle, cone, inner hole, groove, curved surface, etc
• Special surface requires applicable Sensor for measurement
• Pay attention to working environmental conditions: Temperature -20 ℃~ 40 ℃, Humidity < 90% RH
• Pay attention to environmental conditions during storage and transportation: Temperature -40 ℃~ 60 ℃, Humidity < 90% RH
• Regularly calibrate the instrument with calibrated samples to ensure measurement accuracy
• Avoid violent collisions or scratches to the Sensor stylus
• Pay attention to the remaining power indication in time to avoid affecting the measurement due to insufficient power
• Clean Sensor and Instrument Surface After Use
• When not in use for a long time, it is recommended to store the instrument in a drying and cool place
