I have a Weston 301 meter 0-100 ma scaled meter and wish to make a shunt to
use for screen current in my 4-1000 amp. The screen voltage is 300V I have
used the formula RS=RM/(IS/IM) Okay here is what I used RM = 3ohms meter
resistance IM meter current for full scale =2ma I am thinking I need to
shunt 98ma for full scale
I am just not sure of my math is this the correct formula and am I using it
right? I get .06 ohms
