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.
