Test Preparation
Operation Requirement
WARNING
Before operation, thoroughly check the operating environment of the device again:
Before operation, thoroughly check the operating environment of the device again:
Place the detector in an area with minimal pipeline volume.
Place the detector as close to the product tested as possible to reduce tube volume.
The device is a countertop, directly placed on the desktop or shelf, please pay attention to reserve enough space for tube connection, testing and maintenance.
Air supply pressure should range from 600 to 800 kPa.
Check and Test the Air Source
Check whether all cables are connected. Connect the air supply to the air inlet of the tester. Pay attention to the air supply capacity, if the flow rate is too low, the device will appear slow inflation or low-pressure alarm.
For optimal test performance, it is recommended the air supply pressure used for testing should be between 600 and 800 kPa.
Check the Drive Air Source
There are clearly requirements for the pressure range of the driving air supply. The required pressure should be provided in accordance with the instructions on the label to ensure normal operation.
NOTE
The fluctuation of the driving air source exceeds the required range will lead to fluctuations in the test data, if the pressure of the driving air supply does not meet the minimum requirements, the tester will not work correctly.
Start
The External AC Power Supply Connection
Tube Connection
It is recommended to use the high-quality ferrule connectors and rigid air tubes to connect the product under test to the test port as shown in the figure above. In the test, strict air-tightness is required. Use ferrule fittings to ensure no leakage at the joints. For non-test circuits, such as the test air inlet or drive air inlet, standard quick connectors are acceptable.
Before filter maintenance, stop the instrument and disconnect the power. Remove the rear oil-water separator, open the cup and base, then carefully take out the black baffle and replace the white tubular filter element.
Steps for Connecting the Air Source
- Take out the air tube, one side is with a C-type self-locking connector.
- Align the other end of the air tube with the air inlet connector on the device and remove the
nut from the air inlet connector. - The nut of the air inlet connector on the device is placed on the air tube.
- Cover the air tube on the air inlet connector of the device to ensure that the connection is
secure. - Use a tool to tighten the nut and ensure that the nut is securely connected.(Recommend using a 14-inch fixed open wrench or an 8-inch adjustable wrench).
NOTE:
In the test circuit, strict requirements are placed on air leaks. It’s recommended to use card sleeve connectors for pipeline connections to ensure no leaks occur at the joints. For non-test circuits, air leak requirements are less stringent. For example, common quick connectors can be used for the test air supply inlet and the driving air supply inlet.
Using soft tubes, such as silicone tubes may cause elastic deformation that compensates for pressure drops due to equipment leakage, leading to significant interference with the detector’s tests and incorrect judgments.
WARNING:
If it is found that there is dirt around the outlet port, it is necessary to check the sealing of the tester. The dirt may lead to problems with the sealing of the valve, resulting in a decline in tester performance or failure, affecting the quality management of the user.
Air Outlet Inspection
Avoid dirt and blockage around the outlet port to affect the exhaust.
Use a plug to plug the high-pressure connector and tighten it.
Use a plug to plug the low-pressure connector.
Remove the vent valve bolt and install the test connector. The test connector must be installed smoothly without air leakage.
NOTE:
If a second leak test is required, remove the vent valve bolt and exhaust.
If the first test fails, retest after passing the test.
It’s ok if the third test is still passed. If it fails, check the air leakage position, and reinstall or replace the relevant parts after the air pressure inside the body is emptied.
Please wait for more than 5 minutes before the next test.
Before the next test, please ensure that all the air inside the pack cavity has been completely vented, otherwise, it may cause the battery pack to bulge or damage the casing.
