3M 965AMS User Manual

The plastic battery holder that comes with the unit uses six 

“AA” alkaline batteries (alkaline batteries are not included).
Use alkaline batteries only when the NiMH battery pack is 

discharged and the AC adapter is not available. Typical lifetime 

of the alkaline battery pack is twenty hours of normal use (less if 

you use the backlight frequently, use the optional /SA or /ADSL 

features heavily, or work in very cold weather). The alkaline 

battery pack is installed the same way as the NiMH battery pack.
Note: The battery holder has protection against accidental 

The 965AMS tester comes with a Red/Black test lead pair, a 

Blue/Yellow test lead pair, and a separate Green test lead. The 

Red/Black and Green test leads are used for most measurements. 

The Blue/Yellow lead pair is used with some TDR modes (not 

in the 965AMS-B tester), and the Yellow lead is used with RFL. 

The shorting “strap” that comes with the unit is used with RFL. 

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.
