With help from Curtis I have used this method to test a number of circuit boards as I discussed on the Forum, but this time using Workstation to store the results.
Particularly useful useful for finding high resistance shorts between connector pins.
I found that the most reliable results against speed are obtained with a delay of 0.5 second using an Agilent 34410A + workstation on my ProTrack + Scanner setup.
I work on agricultural circuit boards that are exposed to a damp,& dusty environment, and although only operating at 12 V.D.C. have lots of available current were a resistance of a few M Ohms, can rapidly fall to a few Ohms, and start heating up the area between connector pins.
As can be seen on my attached photo, and end up like the fire in second photo.
1 M Ohm to 50 k Ohm short between pins can cause some strange CAN BUS faults for the Farmer.
If ever I get my hands on a 3200S, would be interesting to find the output from the relays and see if the same thing can be done. That is if it uses a similar internal setup?
If anyone wants details the adaptor used for this test just reply here.
