Using a Gaussmeter properly?

[DrNewcenstein]

Ok, I bought this:

Is there a specific distance I have to hold the magnet to get the correct reading? Obviously the closer I hold it the higher the reading, and vise-versa. And is there a chart showing what magnets (A5, A2, etc) should read?

This meter has LEDs and measures in milliGauss (mG) - 1.5 to 30. Should the lights stop at a certain point or do I take the peak reading or the average?

There's a chart on the back showing various sample measurements - tv at 1 foot reads 20mG. What, I gotta do like calculus? :lol:

One of the funny things on magnets is that you can't decide based on your readings whether its an A2 or an A5. You only can say if its a A2 it is very strong or (on the same readings) if its an A5 its very weak.
So you dont need a Gaussmeter, a fridge does the same.

Magnets are going to be higher than that thing can read, I would think...

I dunno. My CS Duncan Distortion JR's box label says the Gauss is 15, and if I hold the pickup in front of the meter it tops out at 15.

However, with no clear instructions on measuring magnets specifically relating to pickups, this is a case of the method being influenced by the results (Z=X+Y rather than X+Y=?)

i have an analog gaussmeter. i put the edge of the meter against whatever i am measuring, move it along the surface and take the highest reading. mine goes to 50 and some alnico 5 and ceramic magnets are stronger than that.
