your testing insulation between conductors. you do not short it together at any point

you want the highest possible resistace. you do not 0 test leads for IR, but shorting them together to get 0 before a test ensures they are correctly connected to tester

if you ir test a short piece of cable say 1mm csa would you get a reading and what should it be assuming the cables good

The Don would expect a high reading, perhaps 299.

If you IR tested a brand new reel of T&E I would expect to get >299mohms on all the readings....

DO NOT CONNECT TOGETHER THE OTHER END

for a new cable, expect a reading higher than your test kit can measure

so the test leads have no resistance

your testing the IR, try one clip on brown one on blue but dont join the other end.
