Principle
The low/high temperature test chamber adopts the original French "Taikang" fully enclosed Compressor and unit or binary low temperature circuit design through the refrigeration system to achieve rapid cooling and temperature control. The heating system uses a fully independent nickel-chromium alloy electric heater to heat up, combined with a multi-wing blower strong circulation air path to ensure uniform distribution of temperature and humidity in the test area. The temperature and humidity control instrument corrects the environment changes in real time through the automatic calculation function to maintain accurate and stable, and supports program editing and remote monitoring.

Steps
1. Connect the power supply to ensure that the voltage is AC280V +/- 10% or AC380V +/- 10%, 50Hz three-phase five-wire system.
2. Open the control instrument, select the Chinese and English interface, and edit or select the test program.
3. Set the temperature range, time and other parameters, each time can be set up to 99 hours and 59 minutes.
4. Start the device, observe the screen real-time Linear dispersion, and monitor the test process.
5. After the test is completed, turn off the device and disconnect the power.
Notice
• Operating Environment Temperature should be 5 ℃~ 30 ℃, humidity ≤ 85% R.H.
• Regularly check the replenishment tank to avoid protection triggers caused by water shortage.
• During maintenance, use the door opening design for waterway and circuit system maintenance.
• Avoid artificially touching the controller screen to prevent misoperation and shutdown.
• The test hole is closed in time after use to prevent energy loss.
• Pay attention to the status of the safety protection device when the equipment is running, and immediately stop for inspection in case of abnormality.
