I have an old Agilent 1100 HPLC with two detectors (RID+VWD).
I've had some problems of sudden power failures. Every modules have a power failure at the same time for less than a second and then go back on power on.
I installed a UPS and changed the LAN card, but I still have issues.
I verified the best I could all wires and connexions, but how can I know from which one it comes?
