I had check all my multimeter's about correct calibration ,
and I have it on my bench for quick tests too.
I had use low wattage resistors on it,
and I can not use it for currents over 600mA .
And so it can be used so to " match" ( find ) the resistance value for LEDs or small DC motors.
You can find the resistor that you need so to keep an computer fan silent at easy The truth are that the resistors decade box, and the voltage calibrators,
are not items for daily use .
But with out them , you do have the feeling that something missing among your tools.
