terminal, indicates the user must refer to the 
manual for further information. 

 

This symbol, adjacent to a terminal, indicates that, 
under normal use, hazardous voltages may be 
present 

 

Double insulation 

 

 

SAFETY NOTES 

  Do not exceed the maximum allowable input range of   

any function 

  Do not apply voltage to meter when resistance function  

is selected. 

  Set the function switch to OFF when the meter is not in 

use. 

 

WARNINGS

 

  Set function switch to the appropriate position before  

measuring. 

  When measuring volts do not switch to 

 

current/resistance modes.

 

  When changing ranges using the selector switch always 

disconnect the test leads from the circuit under test.

 

  Do not exceed the maximum rated input limits.
