Scope
Scope: This procedure applies to the initial calibration, subsequent calibration, and in-use inspection of transient resistance testing equipment. Transient resistance testing equipment mainly includes two types: transient resistance continuity testers and instantaneous disconnection testers. This specification applies to the calibration of devices with the following functions: a) Transient resistance continuity tester Transient resistance measurement range: 0.5Ω~100Ω; Resistance measurement time interval: 1ms; b) Instantaneous disconnection tester Transient resistance measurement range: 0.5Ω~5kΩ; Instantaneous disconnection time range: 0.1μs~99.99μs; Main technical content: 1) Scope This procedure applies to the initial calibration, subsequent calibration, and in-use inspection of transient resistance testing equipment. Transient resistance testing equipment mainly includes two types: transient resistance continuity testers and instantaneous disconnection testers. This specification applies to the calibration of devices with the following functions: a) Transient resistance continuity tester Transient resistance measurement range: 0.5Ω~100Ω; Resistance measurement time interval: 1ms; b) Instantaneous disconnection tester Transient resistance measurement range: 0.5Ω~5kΩ; Instantaneous disconnection time range: 0.1μs~99.99μs; 2) Overview a) Principle The transient resistance continuity tester is a dedicated testing instrument used to monitor whether the transient contact resistance of the conductive ring increases or disconnects during the sliding process. The transient contact resistance of the conductive ring is related to the position of the brush line, pressure, and the wear degree of the ring, and is a function of resistance and position, pressure, and wear degree. When the rotational speed of the conductive ring is fixed, the position, pressure, and wear degree will correspond to time, and then it will become a function of re
