Is this center negative?

Chris, Most of these DC power supplies are center positive. The connector configuration (polarity) is always displayed on the front or the back label on the PS.

The diagram on the Power Supply shows that the center is (+), outside is (-).

No it is not,so there is no bubble to center,it is a jeweled dial,faster and sure

It looks the same. I have had 2 pumps so far and both have the positive and negative reversed. Be careful you might have to re adjust the positive and negative so it pumps correct.

The polarity of the T connectors is standard -- the top bar of the T is positive and the post is negative. The labels on the diagram in the instructions are misleading since they are opposite to the orientation of the T sockets.

Mine is, but not sure if it is supposed to be or not. No problems here though.

It's not reversed polarity. If the polarity is reversed the 63001 is completed non-responsive. I have the same unit. It is displaying -1, but otherwise appears to be functioning normally

Yes A negative sign (-) will display on the meter when checking DC voltage and the meter leads are incorrectly placed on the voltage source. When the meter leads are reversed, then the negative sign will not appear.

You might go to Radio Shack and bring your Kodak picture frame there and tell them that the outer circle is negative and the inner circle is positive. This is what my adapter says when I look at the power plug. Hope this helps. Thank Joe

Polarity is embossed on the ceramic substrate with traditional symbols of positive and negative. If you can't locate, use s multi meter as it is a diode and only passes current from negative to positive

There's a picture on the back just above the pins plug the balance plug in to it starting from negative(black) where the negative sign is

If what you mean is the part that plugs into the device (not the wall) then yes the center part on the inside is positive and the outer shell is negative. I BELIEVE, NOT 110% SURE THOUGH.

There is no positive and negative. It's basically an on and off switch. It will work on ether side. I use it on my Model A Ford to cut the battery off. I put it on the negative side of battery like is "battery-switch-cable to starter and rest of car". Model As are backwards. On modern cars I would put it on the positive side. For the price it works great.

The center post is NEGATIVE, the outer shell is POSITIVE. This is opposite of what many common connectors for power supplies have. You need to look on the Casio specifications for the AD-5. Also, there is a small diagram on the plastic case of my CT-700, where the AD-5 plugs into the keyboard, that shows this polarity requirement. Jay Daugherty is incorrect.

No, but there is a "reverse mirror" function on the top that will reverse the negative. This enables you to continue to slide the negatives through.

by the look of the drawing on the side, 4 goes to the positive on the coil on the SSR and 3 goes to the negative to the coil of the SSR. but I would be surprised if it polarity matters on the Solid State Relay.

Sorry, but I don't remember. Mine was used with a 12v DC converter for a light strip, so polarity is a definite concern
