Hi,
I was looking for a device to test solenoid valved. It's easy to check for continuity and magnetisation, but checking the actual operation is not always easy.
I couldn't find what I wanted, so I made my own.
It has proved useful when checking disinfection valves on Fresenius without the machine then requiring a mandatory disinfection/rinse.
Also used to check chair actuator motors.
If anyone knows where I could get a commercial version that would be good as it was a bit fiddly to make this prototype.
USB rechargeable (battery from a rechargeable vape!), Battery level indicator, output voltage display, capable of 2A - ish.
