Problems solved by technology
[0002] In the current chemiluminescent in vitro diagnostic instruments, photomultiplier tubes are usually used to detect light signals. Photomultiplier tubes are extremely sensitive to light signals. If strong light is encountered when power is applied, photomultiplier tubes will be greatly damaged. To reduce this disadvantage, the instrument in the prior art only energizes the photomultiplier tube when the instrument detects a signal, and does not energize when not detecting, so as to avoid the damage caused by the photomultiplier tube being exposed to the strong light of the external environment, but this In this way, the power-on time of the photomultiplier tube is too short, so the signal is not easy to stabilize, and the signal is prone to fluctuations when it is turned on again

Photomultiplier tubes are extremely sensitive to light signals. If strong light is encountered during power-on, the photomultiplier tube will be greatly damaged. To reduce this disadvantage, in the prior art instruments, the photomultiplier tube is energized only when the instrument detects a signal, and is not energized when it is not detected, so as to avoid damage caused by the photomultiplier tube being exposed to the strong light of the external environment. In this way, the power-on time of the photomultiplier tube is too short, so the signal is not easy to stabilize, and the signal is likely to fluctuate w...
