IR Port
The IR Port on the top of the 900AST tester is used
for uploading TDR traces to a personal computer. A
special IR adapter cable is available for interfacing
with a laptop or PC. 3M provides a program (PC
Link_900AST) for saving/viewing/printing files on
a personal computer.
Test Leads
The 900AST tester comes with a Red/Black test
lead pair, a Blue/Yellow test lead pair, a separate
Green test lead, and a pair of special, coaxial TDR
test cables.
The Red/Black and Green test leads are used for
most multimeter-type measurements. The Blue/
Yellow lead pair is used for RFL and Contact
Resistance. The coaxial test leads are used only for
TDR. Keep the test leads clean and dry at all times
to insure best accuracy of the measurements. Use
soap and water to clean them if necessary.
