6. Operating Instructions
- Power On: Turn on the main power switch. The control panel should illuminate.
- Set Test Parameters: Use the touch screen control panel to set the desired laboratory temperature, saturated air barrel temperature, and test duration according to the specific test standard (e.g., NSS ACSS or CASS). The imported temperature controller allows for manual or automatic PID control with settings up to 999 hours.
- Load Samples: Carefully place the test samples inside the chamber, ensuring they are positioned to allow for even spray exposure and proper drainage.
- Close Cover: Securely close the test chamber cover. For large models, the pneumatic cylinder will assist in opening and closing.
- Start Test: Initiate the test cycle from the control panel. The chamber will begin heating and humidifying, and the precision glass nozzle will start spraying the salt solution.
- Monitor Test: Periodically monitor the test parameters on the control panel. Ensure the water level is sufficient; the automatic water filling system will manage this, but warnings will display if manual intervention is needed.
- Test Completion: Once the set test duration is complete, the chamber will automatically stop the spray cycle.
