I have 3 multimeters here and I was trying to read current from a power supply to a mother board, so i noticed all 3 were giving me different readings.
I take a closer look at them and their specs

i know my craftsman 19dollar meter is not as reliable as the keithley 2000 or the Tektronix multimeter but what is the key spec to look at that is making the difference?
my scenario is
craftsman meter is reading: 1.4Amps
Tektronix meter is reading: 348mA
Keithley meter is reading: 550mA
I noticed that using the tektronix meter by playing with the range button that display it reads 1.4Amps the same way as the craftsman meter... but when i increase the range to 500 from 10 the current reading goes to 348mA this makes me believe that is an accuracy range and the 348mA is a better reading, this is what i was trying to look for in the specs sheets for all three meters but i get lost in the information could anyone help?
