Default Interpreting data from a motor monitor

I have just bought a motor monitor, another toy to play with!

How do I interpret the data I get from it; it gives Amps and RPM, Max RPM and Max Amps. It is one of the Much More /Orion ones and stages the voltage as it tests the motor at 1.2V, 2.4v, 3.6v, 4.8v, 6.0v and 7.2v.

What am I looking for to tell if the engine is good, high Amps, RPM or a combination of both.

Also what sort of numbers do you get from a good stock motor and a 540 Johnson.

Thanks

High amps usually indicate a strong motor, however with no load it's not always an accurate assessment of a motor. A good motor could pull low amps, but be fast on the track. Likewise, a motor could pull 10+A but be a dog. The best way you can use the motor monitor would be to compare motors on it to the numbers you get from a motor that you know performs well on the track. Also, make sure nothing is binding, because that will make the motor draw more amps. (squeeze the armature when its running and the amps will shoot up)

Hope this helps somewhat, someone else will have to help you with the silver can, I don't jack about those.

Default Motor Monitor Numbers

Has anybody got any numbers from their own testing of motors on a motor monitor.
I am after a Johnson motor & a CO27, and maybe a monster. Amps & RPM.
Thanks
