Lyman ® Electronic Digital Trigger Pull Gauge User’s Manual
Operating Instructions for Lyman’s Electronic Trigger Pull Gauge IMPORTANT! Make sure all firearms are unloaded and in a safe condition before using this product! The Lyman Trigger Pull Gauge is a battery operated (2 – AAA batteries) electronic gauge designed to accurately measure trigger pull weight up to 12 pounds. The Lyman Trigger Pull Gauge features a telescoping trigger pull rod that slides into the housing for easy, compact storage.
Cock the firearm. Since the firearm needs to be dry fired when taking trigger pull readings, we recommend the use of snap caps such as Lyman’s A-Zoom brand. Pull the trigger with the trigger rod until the firearm dry fires. For best results, keep the trigger rod parallel with the bore of the gun while taking readings. A slow, steady pull is best. Small weight readings may appear as the gauge is moved into place. These are of no concern, as fluctuations up to 1 ounce will not be recorded.
