SAFETY SYMBOLS 

This  symbol  adjacent  to  another  symbol, 
terminal or operating device indicates that 
the  operator  must  refer  to  an  explanation 
in  the  Operating  Instructions  to  avoid 
personal injury or damage to the meter. 

This 

WARNING

  symbol  indicates  a 

potentially  hazardous  situation,  which  if 
not  avoided,  could  result  in  death  or 
serious injury. 

This 

CAUTION

  symbol  indicates  a 

potentially  hazardous  situation,  which  if 
not  avoided,  may  result  damage  to  the 
product. 

This  symbol  advises  the  user  that  the 
terminal(s)  so  marked  must  not  be 
connected  to  a  circuit  point  at  which  the 
voltage  with  respect  to  earth  ground 
exceeds (in this case) 500 VAC or VDC. 

This  symbol  adjacent  to  one  or  more 
terminals 

identifies 

them 

as 

being 

associated  with  ranges  that  may,  in 
normal  use,  be  subjected  to  particularly 
hazardous voltages. For maximum safety, 
the meter and its test leads should not be 
handled 

when 

these 

terminals 

are 

energized. 
This  symbol  indicates  that  a  device  is 
protected  throughout  by  double  insulation 
or reinforced insulation.
