Operation Procedure

Pre-Startup Inspection

Confirm that the power supply voltage (usually 220V/380V) matches the equipment requirements and is securely grounded.

Check that the xenon lamp cooling system (water-cooled or air-cooled) is functioning properly. For water-cooled systems, ensure sufficient coolant and no leaks.

Clean the sample chamber to prevent any remaining foreign matter from blocking the light source or affecting the temperature and humidity sensor.

Sample Placement

Secure the sample to be tested on the sample holder, ensuring that the surface is evenly exposed to the light source and avoiding overlap or obstruction.

Adjust the distance between the sample and the lamp according to the test standard (such as ISO 4892 or ASTM G155).

Parameter Settings

Use the control panel to set the light intensity (usually 0.3-1.2 W/m² @ 340nm), chamber temperature (40-80°C), black panel temperature (50-110°C), humidity (10%-75% RH), and cycle mode (light/dark/spray).

Select a filter type (such as quartz/borosilicate glass) to simulate different spectra (full spectrum, UV cutoff, etc.).

Starting Operation

Start the cooling system first, then ignite the xenon lamp (to avoid sudden high temperature damage to the lamp).

Monitor initial data to ensure that the temperature, humidity, and irradiance are stable within the set range.

Shutdown Procedure

Turn off the xenon lamp and wait for the chamber to cool to a safe temperature (<40°C) before shutting off the cooling system and main power.

In emergencies, use the "Emergency Stop" button to avoid direct power outages that could damage the lamp.

Daily Maintenance Tips

Xenon Lamp Maintenance

Check the lamp life regularly (usually 1000-2000 hours) and replace it if it is aged or blackened.

Wear gloves when replacing the lamp to avoid fingerprints that may affect light transmittance.

Cooling System Maintenance

Water-cooled models: Check the cooling water conductivity monthly (recommended <10 μS/cm), replace with distilled or deionized water, and clean the filter.

Air-cooled models: Clean dust from the fan blades and heat dissipation vents quarterly.

Cleaning and Calibration

Wipe the sample chamber reflector and filter weekly to prevent dust accumulation that could affect irradiation uniformity.

Calibrate the temperature and humidity sensor and irradiance probe every six months (recommended by a professional organization or manufacturer).

Other Component Inspections

Inspect the sample holder for corrosion and replace damaged fixtures promptly.

Spray System Test: Run the spray function regularly to prevent nozzle clogging.

Precautions

Safety Precautions: Do not open the chamber door during operation to avoid UV damage; wear protective glasses.

Environmental Requirements: Allow 50cm of heat dissipation clearance around the equipment to avoid high temperatures and high humidity (recommended ambient temperature ≤ 25°C).

Abnormal Handling: If an alarm (such as overheating or water shortage) occurs, immediately pause the test and troubleshoot the problem before restarting.

Record Retention: Detailed records of each run parameters, duration, and equipment status are kept to facilitate tracking of performance changes.
