Hi,

Thank you very much for the very? kind offer.?

Any photos and physical measurements you can take would be very helpful

There are 4 SMA connectors, which connect to Hcur, Lcur, Hpot & Lpot. Can you measure with a multimeter and determine which pieces of the fixture connect to each of the 4 connectors? It looks as though Lpot and Lcur connect to one side, and Hpot and Hcur connect to the other. But where do each go?

What pieces are electrically isolated from all 4 connectors, but electrically connected to the chassis?

The manual says that there are various values of capacitance, depending on what size plates are connected. Would I be right in assuming that if you assemble this, but don’t fully tighten the thumb screws, that those capacitance values decrease, since you are increase the spacing between the plates?

Am I right in assuming that the gap the manual speaks of, is the gap between the electrodes when fully assembled?

I assume that the ceramic is fixed to each side, and can not easily (if at all) be removed. Can you see how it is fixed to the body? I assume that ceramic sits a certain distance below the top surfaces of each side. What is that distance?

Is the ceramic tapped, so you screw into that when you insert the electrodes? If so, how far approximately do the screws go in? Can you measure the depth of where it's tapped?

I am obviously seriously confused about some aspects of the assembly.? I can't understand why increasing the thickness of the electrodes increases the gap. I would assume if you increase the thickness of the plates, that would decrease the gap between the electrodes, not increase it.

Let's assume hypothetically the ceramic is 4 mm below the surface on each side, so the space between the two pieces of ceramic are 8 mm. Then if you insert 3 mm thick electrodes each side, you take up 2 x 3 = 6 mm with metal, leaving a gap between the electrodes of 8-6=2 mm. That would match one of the data pints given in the manual.

3.0 mm thickness, 2 mm gap

Now, if you use thinner electrodes (say 1.3 mm) I would expect the gap to increase to 8 - 2 x 1.3 = 8 - 2.6 = 5.4 mm. But instead the? manual says

1.3 mm thickness, 0.3 mm gap.

How can using thinner electrodes result in decreasing the gap? I would have expected the dead opposite! I'm obviously totally mis-understanding the construction there.

There appears to me to be 3 connectors for liquid.

1) One of the side, at an angle, where liquid is inserted.

2) One at the bottom, where liquid is drained.

4) MAYBE one at the top, where I have put a question make on this drawing,

I can understand that trying to put liquid into this structure, with the bottom sealed, would be impossible unless the air could get out. So I assume at the top is an air-vent, where I have put a question mark on the attached diagram. Is that true?

There appears to be a lip on the electrodes. Am I right in assuming that the lip is placed in such a way that it goes over the ceramic? I assume that it perhaps helps centre the electrodes on the ceramric.

As you can see, I am a bit confused about the construction of this!
