Safety   

DANGER 

  Engines produce carbon monoxide which 

is  odorless,  causes  slower  reaction  time, 
and  can lead  to  serious  injury. When  the 
engine  is  operating,  keep  service  areas 
WELL VENTILATED or attach the vehicle 
exhaust  system  to  the  shop  exhaust 
removal system. 

 
 

  Set  the  parking  brake  and  block  the 

wheels  before  testing  or  repairing  the 
vehicle. It is especially important to block 
the wheels on front-wheel drive vehicles; 
the parking brake does not hold the drive 
wheels. 

 

  Wear  an  eye  shield  when  testing  or 

repairing vehicles. 

 
Exceeding  the  limits  of  this  meter  is 
dangerous.This  will  expose  you  to  serious 
or  possibly  fatal  injury.  Carefully  read  and 
understand 

the 

cautions 

and 

the 

specification limits of this meter. 

  Voltage between any terminal and ground 

must not exceed 1000V DC or 750V AC. 

 

  Use caution when measuring voltage above 25V DC or 25V AC. 

 

  Circuit tested must be protected by a 20A fuse or circuit breaker. 

 

  Do not use the meter if it has been damaged. 

 

  Do not use the test leads if the insulation is damaged or if metal 

is exposed.
