Hot and cold impact testing machine is always in the application of the test process, but sometimes there may be problems such as faults, which is a common short circuit, why a short circuit? If you encounter this problem , you can use the following method to deal with: 1. The display value of the thermal shock tester is lower than the actual value or the displayed value is not stable. It may be that there is dirt inside the protection tube. The treatment method is: use a special detergent to remove the dirt; if the displayed value indicates If it is a negative value, it is caused by the short circuit of the thermal resistor or the wrong connection. Processing method: Correct the wiring and handle the short circuit problem. 2, short circuit is generally very easy to judge, just a multimeter can be. Measured with the multimeter's “×1Ω†file. If the measured resistance is less than R0, it may be a short circuit. If the measurement indication is infinite, you can determine the open circuit. 3, short-circuit easier to handle, as long as it does not affect the length and thickness of the resistance wire, find the short-circuit at the dry, reinforced insulation can be. If it is a circuit breaker, then the length of the resistance wire must be changed during processing to affect the resistance value. Therefore, only the replacement of a new resistor body is required, but if soldering is used for repair, it must be verified after passing the soldering. 4. Exclusivity: Each time an environmental or reliability test is conducted, the thermal shock tester has strict rules on the types, magnitudes, and tolerances of environmental factors, and excludes the environmental factors that are not required for the test to penetrate them so that When determining and analyzing product failure and failure modes during or after the test, provide the exact basis. 5. Safety and reliability: Various protection and alarm measures and safety interlocking devices for the test equipment of the thermal shock test box should be improved to ensure the safety and reliability of the test personnel, the tested products and the thermal shock tester itself. Test box. Thermal shock test box commitments: 1. Our company's product quality assurance system is strictly in accordance with the requirements of the ISO9001 quality standard. 2.
