Introduction 

 

Chapter 3 explains how to make measurements.   
You could turn the Meter off by turning to 

OFF

 position or set up the sleep mode from 1-30 minutes.  

Please must ensure the Meter is not under sleep mode if you turn the Meter on but without display. 
To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery 
as soon as the battery indicator “ ” appears. 
 

A. Scope
