I have been using a certified iso-tech idm 105rms for work with minimum range 400 ohm.
Probe to probe short measured 0.4 ohm and it did fine measuring coil resistance(I guess).
Then I went to purchase a pocket size amprobe pm55a, planning to use it when travel.
The minimum range is 600 ohm, shorting probe to probe measured zero... which I thought was perfect.
Till I measure the 1.5 ohm coil(as measured with iso-tech idm 105rms) turn out zero ohm ...>_<...
On the mail transit I've a cheap china made smd tweezer which promise 0.1 at 300 ohm which I've 50/50 confident for now.
Makes me wonder what you chaps use for measuring resistivity. Those promising sub ohm meter easily cost more then 500 buck ...>_<...
