Title: BT Tester 301B Time Domain Reflectometer
Post by: downwind27 on September 17, 2019, 07:59:07 pm
We have one of these testers on our heritage railway. After years of storage it is now needed and of course it's not working - dead as a doornail. The batteries have been replaced and are OK. Does anyone have a schematic diagram or service manual for this item?
