LM5 Overview 

 
The LM5 can be operated as a standalone instrument. Complete with 4 alkaline “AA” batteries 
the LM5 will operate on full power for at least 3 days. The LCD panel back light does go out 
after 20 seconds when not in use in order to conserve energy.  If using the LM5 with an external 
sensor it 

must

 be connected to an external battery. 

Note: The LM5 is not programmed for auto shut-off.  It is recommended user turn off the 
unit when not in use.   
 

The LM5 is also expandable to include a remote sensor. This sensor can be installed on moving 
parts such as blades, buckets and forks etc. depending on the application. The Menu will change 
to “EXT” when cable is connected.
