I noticed when I try to use my HP dual power supply 6227B, if I have it in tracking mode, and connect earth (oscilloscope) it stops output. Even if I put a jumper banana plug from Ground to the joined channels it drops off.
is it broke or is this how it works? it means you need everything connected to it to be floating when its in tracking mode.
I think I just did a whole bunch of tests that basically provided no power because I set the voltage, then set it to current monitor mode, then connect the scope. Unless it was working and broke. IDK I lost track of what exactly was happening because I am mega pissed off at this PCB.
if someone has one, can you just tell me what happens to the meter when you connect ground to the shared 0V terminal from the PSU when its in Tracking mode??
