The dust test chamber is applicable to the IP5X and IP6X dustproof test of the products.

Q1: The test chamber cannot be started
A1: Please confirm that the power supply of the test chamber is connected to the correct voltage and frequency. The power supply of the equipment is three-phase, and the wrong phase sequence will also lead to failure to start the machine. Please exchange the phase sequence of any two phases of the power supply before attempting to start the machine.

Q2: During the test, there will be dust floating out of the door seam
A2: The door is not closed tightly. In order to avoid dust flying out, the doors of the test chamber are designed to be closed tightly. When closing the door, first pull the door handle outward, press the door firmly to the test chamber, then release the handle, and press the door and handle firmly. If the large dust chamber is a double door, close the left door first and then the right door in the same way. Please refer to the following video:

In addition, after the service life of the dust chamber is long, the aging of the sealing strip of the door frame will also cause dust to float out. Please check and replace the sealing strip with a new one.

Q3: About sand and dust
A3: If the dust prevention test is carried out in strict accordance with the standard, after every 20 tests, it is necessary to remove all the sand and dust in the test box and replace them with new ones. Therefore, sand and dust are consumables.
After the dust sent with the test chamber is used up, the customer needs to buy it by himself. It can be purchased from LISUN or local. Purchase medical talcum powder which is harmless to human body. The particle size shall not be greater than 75um.

Q4: How to confirm test results
A4: If the sample is short circuited and extinguished during the test, it is definitely unqualified. If the sample still lights up normally, it is necessary to take out the sample, wipe the dust off the surface, and then open the sample to check whether there is dust entering the interior. If there is dust entering, it is also not up to the standard.
For specific details, different industries have different rules. Please refer to the corresponding industry standards.

Q5: How to change the display unit of the vacuum pump pressure meter
