How the CMO

works

To measure the load current used on different power supplies, measure DC voltage

across the sense (CMO) resistor. The value of the resistor is 0.025

R ± 1%. Calculate

the current using this equation:

I = U/R

where

 I = current in Amps

 U = measured voltage in Volts

 R = 0.025 Ohms
