What are the factors affecting the test results of the Tracking Tester?
Tracking tester is used in the research, production and quality inspection departments of lighting equipment, low-voltage appliances, household appliances, machine tools, motors, electric tools, electronic instruments, electrical instruments, information technology equipment, and is also suitable for simulation tests in the industries of insulating materials, engineering plastics, electrical connectors and accessories.
1、Tracking Tester's sample pretreatment
Because the standard requirements of the sample surface should be clean, there will inevitably be some dirt, such as release agent, oil, dust, etc., so the sample surface should be cleaned. Commonly used cleaning methods are distilled water, dry cotton balls and anhydrous alcohol. Among them, anhydrous alcohol is the more ideal choice because it not only cleans grease, but also volatilises on its own, avoiding the effects of other cleaning methods that may enter the interior of the instrument.
2、Use Tracking Tester to test surface flatness, test size and thickness
If the test surface is not flat or has scars, it will affect the test results and lead to deviation. At the same time, the size of the sample needs to meet the requirements specified in the standard, usually 15mm * 15mm * 3mm. if the size does not meet the requirements, the electrolyte may flow from the edge of the sample, affecting the validity of the test.
3、The resistivity and purity of the electrolyte
Platinum black conductivity electrodes are often used in the electrolyte for testing, but platinum black conductivity electrodes are easily inerted, resulting in inaccurate resistivity tests. Therefore, it is necessary to determine the ideal performance of the platinum black conductivity electrode and ensure that the resistivity of the test solution is accurate. Meanwhile, impurities in the electrolyte will also affect the test results, and attention needs to be paid to the purity of the distilled water used in the preparation of the electrolyte.
2、Voltage and current and other artificial intelligence automatic adjustment system, greatly reducing or even without human intervention to achieve the test conditions.
3、Optional:Remote monitoring and troubleshooting function: in the case of user authorisation, the equipment can be read through the wireless network remote technology of the operating state, the fastest speed to accurately determine the equipment failure, to provide the most rapid maintenance services.
4、The equipment is divided into the host and the fume cupboard two parts, test room space is limited, can be more than one flame retardant equipment to share a fume cupboard, more effective use of resources, but also easy to clean.
5、The host adopts the control part in the lower part, the test part in the upper part of the structure mode, the design is suitable, easy to operate.It also effectively reduces the aging of electronic components caused by high test temperature and prolongs the service life of the equipment.
6、Using 7-inch colour touch screen + PLC display and control, the overall use of more stable, more user-friendly operation.
2、The angle between the electrodes during the test is 60°±5°, and the spacing is (4±0.1mm).
3、The two poles on the specimen force were 1.0N ± 0.05N.
4、Applied voltage: 100 ~ 600V, short-circuit current in 1.0 ± 0.1A, the voltage drop should not exceed 10%, when the test circuit, short-circuit leakage current is equal to or greater than 0.5A, the time to maintain 2 seconds, the relay action, cut off the current.
5、Precision dripping amount of stepping motor precision control dripping system, to achieve self-operating system that is not affected by various environments.
6、Dropping device time constant adjustable, precise control of the drip volume size 44~55 drops/cm2 and drip time interval 30±5 seconds.
7、Dropper outer diameter: 0.9-1.1mm.
8、Precision drip volume stepping motor precision control drip system, to achieve self-operating system that is not affected by various environments.
9、With 500g of analytical pure NH4CI (users according to the requirements of their own solution)
10、Control mode: touch screen + PLC control.
11、With wireless remote control, when closing the fume cupboard, you can start (stop) the test by wireless remote control.
12、Electronic balance (user's own)
13、Fume hood volume: 0.5 cubic metres, material A3 steel spray paint, the inner wall is matte black, with lighting, illumination ≤ 20lx, more convenient to observe the test flame.
