GB2423.1-2008/IEC6008-2-1-2007、GB/T 2423.2-2008、GJB150.3A－2009、GJB150.4A－2009、GB2423.22-2008、GBT 2424.5-2006、GB/T 10589-2008、GB/T2423.3-2008(IEC68-2-3)
Steps
1. Move the machine to the designated position through the bottom PU movable wheel and fix the casters
2. Connect the three-phase 380V power supply
3. Supply water to the equipment through the front-mounted water supply tank
4. Use the touch setting interface to set test parameters
5. Select the program mode or the fixed value mode to run
6. Monitor the test process through the observation window
7. After the test is completed, the data can be downloaded through the USB interface
Notice
• Rated power 7.3kw, current 18A, need to use three-phase 380V power supply
• Samples should be evenly distributed on the sample rack according to the load-bearing capacity of 25kg
• Check whether the protection system function is normal before use
• Pay attention to protection functions such as equipment overtemperature and fan overheating
• Regularly check the overload of the refrigeration system and the overpressure protection of the refrigeration unit
• Device weight is about 265kg, pay attention to safety when moving
• A special sealing plug should be installed in time after the test hole is used
• If there is a failure alarm during the operation of the equipment, it will automatically shut down
