Test Procedures
Install test samples in universal sample racks and close chamber doors securely.
Set test parameters on the touchscreen HMI or select a preloaded IEC/UL test profile.
Adjust target temperature, humidity, heating/cooling rate, and test duration as required.
Start the test sequence; system performs automated ramping and environmental cycling.
Monitor real-time conditions via touchscreen or remote connectivity.
At completion, allow chamber to return to ambient temperature before retrieving samples.
Export test reports via software interface for analysis.
Maintenance Information
Regularly inspect and clean chamber surfaces to avoid residue accumulation.
Replace HEPA filters, heating elements, and refrigerant filters as recommended by the manufacturer.
Perform NIST-traceable calibration of temperature and humidity sensors annually.
Verify door interlocks and emergency shutdown circuits before each test series.
Store the unit in a dry, ventilated environment when not in use.
