Test Procedures
Sample Preparation
Mount the reflective material or garment on the sample platform using the quick-change fixture.
Ensure the sample area corresponds to the testing aperture and standard requirements.
Calibration
Perform calibration using the included black and white plates to ensure measurement accuracy.
Measurement
Adjust the observation and incidence angles according to the testing standard.
Illuminate the sample with standard illuminant A and record the retro-reflective coefficient via the detector.
Repeat measurements for multiple points or samples as required.
Data Recording
Store test results on the TF card or view on the touchscreen interface.
Generate reports summarizing retro-reflection performance for quality assessment.
Maintenance Information
Regularly clean the detector and light source to maintain measurement accuracy
Inspect and tighten the sample fixture to prevent misalignment during tests
Calibrate the instrument periodically using the included plates
Ensure the touchscreen and data storage system function correctly
Store the instrument in a dry, dust-free environment to prevent sensor degradation
