3M 965AMS Manuel D’Utilisation

The Self-Calibrate function will verify that all of the internal 

circuits and test leads are operating properly. Use self-calibrate:
•  After the first full battery charge before you put the tester in 

service for the first time.

•  Anytime the working temperature changes by more than 

35°F (20°C). Calibrate the 965AMS tester at the same 

temperature at which it will be used.

•  After changing the batteries, or anytime the battery pack 

completely discharges.
