Volt meter wiring

I'm having a little trouble wiring the volt meter that I received. The one I have has 5 pins instead of the 4 that are illustrated on Kal's site. I've attached a link that illustrates the label on the back of my meter. Pin position 4 and 5 is clear to me. It is the first 3 positions that I'm having difficulty with. What do the 2 squiggles on either side of the IN represent and what does the IN represent?

Cheers!

Strange that they changed it! I bet the one labelled "IN" is actually not connected. The two AC lines go to pins 1 and 3, DC power to 4 and 5.

They usually have manuals online that show you sample wiring diagrams. You may want to check just to be sure.

You can also email them. They responded pretty fast to my questions when I blew up both my volt and amp meters the first time around as they weren't clear in their manual about the power supply requirements. Wink

Yeah, I've looked at the manual online. I wouldn't say that it is the clearest manual that I've seen but one diagram I found had a + for pin 1, an IN for pin 2 and a - for pin 3 with the legend indicating that pin 2 was not connected. I am willing to go with this diagram but I was just a little baffled by the IN label for pin 2. http://www.sure-electronics.net/measure,tools/panelmeter%20Vot-new.pdf So If I go by the manual that sure electronics has on their site would the signal in + for DC go to the hot bus or would it go to the relay?

Doesn't matter. It's AC. Put one hot side on pin 1, the other on pin 3. Which way you do it won't matter. It only matters if you're measuring DC (which is what the manual's trying to say in its own obscure way.) Wink

Perfect! Thanks Kal!

My meter came the same set up. Did you have to install it upside down? It Looks like it may be upside down as the word "MINLIN" on the face appears to upside down. This thread was very helpful, Thanks

Spike, Thanks for the quick reply. Good advise on waiting to apply the sealant. Thanks

What does the adjustment screw in these meters do?

How is everyone doing with their volt/amp meters? Looks like lots of posts with problems on these things. I am only asking since I consider this "bling" (flashy extras) on the panel and may give it the nix when building mine.

No offence to Kal's wonderful design, but if I were to do it over agin I would omit the volt/amp meters. They look cool, but that is about as far as their usefulness goes. I suppose you might see indications of a failing element, or pump on the amp meter, but there are enough symptoms that you wouldn't "need" them. The ONLY issues I had with building the control panel were with the meters, although that seems to be a function of getting bad meters from the supplier vice any design or build flaw.
