Thanks cyberwolf for the info im going to pick order one today! To check the resistance of the atty where do you put the positive and negative probes and are all the multimeters set up the same way??
To measure the resistance of an atty or carto, it doesn't matter which probe you use where. The polarity of the an ohms measurement is not important. Just hold one probe to the center part of the atty (with the center hole) and the other probe to the threaded part. When measuring DC voltage, the traditional convention is the RED probe goes to the + or positive side and black goes to the negative side. With modern digital meters though, you wont hurt anything if you don't know which is which. You will just get a reading with a minus sign in front of it such as -3.7. If you do, just swap them.
It gets more complicated measuring the battery voltage under load. It makes it easier if you have a an extra battery connector and a
connector that your atty or carto can screw into that you can solder wires to. If you need that info, I can do a blow-by-blow or it is most likely already covered on another thread that you can search for.
Most meters today are basically the same. Some may have different ranges, current measuring limits and some are auto-ranging etc., but they all are pretty much the same for the basic functions.
