Test Procedures
Install the appropriate specimen and counter-body in the sample holder according to the selected test method.
Set test parameters including load, frequency, stroke, temperature, and test duration via the control software.
Apply lubricant, grease, or solid film sample as specified by the relevant standard.
Start the automated test sequence; friction force and test conditions are monitored and recorded in real time.
After completion, remove samples for wear scar observation and data evaluation.
Maintenance Information
Regular calibration of the friction force sensor is recommended to maintain measurement accuracy.
The contact-free suspension and magnetic guidance system minimizes wear and reduces routine maintenance requirements.
Environmental chamber and sample fixtures should be cleaned after testing, especially when operating at elevated temperatures.
Periodic inspection of electrical connections and sensors ensures long-term system stability.
