want to shunt a multimeter to extend it's ac ampermeter range so
measured with Rish 14s in ohm meter position about 41 ohms
and then measured with Rish 14s its own internal resistance to get 40
ohms
Is this way to much -there is some mistake?
(http://www.multimetercalibrationsaus...shmulti14s.pdf
but cannot find data about it's internal resistance!)
