There was an Italian pocket multimeter, something like a 'Supertester 680R' that used sockets to select the various ranges. It came with a hairpin link which you could put between the Ohms-common and Ohms*1 sockets and then zero the meter at the right hand end of the scale. You put the probes in 2 other sockets and it then formed a 'shunt' low-ohms meter. Worked very well. It's a pity the 2 I have both have faulty meter movements..

I have one of those Megger circuit testing ohmmeters somewhere too. I can't remember what ranges it has. I must dig it out.
