Hello 
Im trying to measure resistance between two pints with a dmm and matrix 2535 with scan mode. I have  3  matrix cards and a DMM
i have connected r0 of all cards together and r1 of all card together,  r0 goes to dmm +ve and r1 to -ve 
my problem is that, my two points can  be anywhere between three cards for eg, test point-1 can can be channel 1 of first card and test point 2 can be channel 50 of third card
i need to measure resistance between channel-1 and channel-2 with scan mode (channel-1 being connected to r0 and channel -2 to r1 in break before make config) so my dmm will measure between r0 and r1 
How can i give scan list simultaneously to card 1 and 3 so that i get a advance trigger when both contacts are made and i can measure using dmm?
as per documents i get a scan advance trigger when the first contact being made, but i need scan advance trigger when both contacts are made
