2.

3.   Press and hold the RANGE button for 2 seconds to exit the Manual-Ranging mode and return 

to Auto-Ranging.

Backlight  

Press and hold the 

  button for 2 seconds to turn the backlight on. Repeat the press to turn the 

backlight off or wait approximately 15 seconds for it to turn off automatically. 

Automatic Power Off 

In order to conserve battery life, the meter will automatically turn off after approximately 15 minutes. 
The meter will “beep” before shutting down. To turn the meter on again, change the position of the 
function switch. 

Low battery indication 

When the 

 icon appears in the display, the battery should be replaced. Refer to the battery 

replacement procedure in the maintenance section.
