How to test the micro regulator-ISO8536-13
Set the flow regulator to the "Open" position, connect one end of the infusion set with compressed air, and close the other end, immerse it in (40±1)℃ water, set the air pressure greater than 50Kpa for 15s, check whether there is air bubbles, and reach the maximum Repeat the test on the scale value 25%, 50%, 75% closest to the digital scale.
Set the flow regulator to the "OFF" position, connect one end of the infusion set with compressed air, and close the other end, immerse it in (40±1)℃ water, apply pressure greater than 50Kpa for 15s, and observe whether the lower end of the micro regulator is open If there is air bubbles, close the open end of the pipeline and keep the air pressure higher than 50Kpa for 15s. Check whether there is any air leakage from the flow regulator.
In the process of turning the fine-tuning to OFF, you can test whether the fine-tuning rotation is smooth.
