Wanted -- 3M dynatel 745 loop tester schematic
« on: January 03, 2019, 10:31:34 PM »
I was given a Dynatel 745 loop tester and am trying to locate the schematic for it. the unit has 5 PCB's in it and all I have found has been the users manual. does anyone know anything about this unit?

It's probably an early version of what we use these days to test the outside plant/copper pairs going to the subscribers. The units we use check things like voltage, resistance, longitudinal balance, capacitive balance, TDR, and even xDSL.
