Hi,
I'm putting a test rig togeather to check cables which have a special plug on each end. I envisage pluging both ends into sockets built into the test rig and the rig shows the resistance on 2 of the cables multiple conductors. There are less than 6 valid resistances on each of the 2 cable conductors that are of interest.
So, I figured I could have a simple DMM display for each of the 2 conductors to dispaly whatever the resistance is on each at the same time. I hoped I could use those cheap panel mount meters but they only come in 2 ohms or 200 ohms 'FSD'... I need zero to 2K or so.
Alternatively (and maybe much easier to implement, cheaper to make and easier to use) I was thinking of a comparitor-based setup with an LED for each valid resistance range, one set of LEDs for each of the 2 conductors. Outside the valid range = no LED = duff cable...
Anyone know of an existing setup I could use for either option... or indeed a better way?
Thanks. MW
