I think Steve has these PSUs as spare parts
sorry, I ran out of ideas
I can offer you that we check the equipment here on our test tank
but I am quite convinced that we won't be able to produce the same problems as you have, I still...
so, the summary is this:
- you measure in a mug of water a stable value
- the value is fluctuating if the probe is in the tank - even when ALL equipment related to the tank is unplugged...
And the lamps are off during your test? If not, please unpower also the lamps.
We had some cases in the past where ballasts or tubes or lamps caused this kind of problems.
Is the illumination maybe the source of interferences?
