To reduce the risk of fire or electric shock, do not expose this product 
to rain or moisture.  The meter is intended  only for indoor use.

To  avoid  electrical  shock  hazard,  observe  the  proper  safety 
precautions  when  working  with  voltages  above  60  VDC  or 
30VAC rms.  These  voltage  levels  pose a potential shock hazard to 
the user.  Before & after hazardous voltage measurements, test the 
voltage function on a known source such as line voltage to determine
proper meter functioning.

Identifies conditions and actions that could result 
in serious injury or even death to the user.

Identifies conditions and actions that could cause 
damage or malfunction in the instrument.

Keep  your  hands/fingers  behind  the  hand/finger  barriers  (of  the 
meter and the test leads) that  indicate  the  limits  of  safe access of 
the  hand-held  part  during  measurement.  Inspect  test  leads, 
connectors,  and  probes  for  damaged  insulation  or  exposed  metal 
before using the instrument. If any defects are found, replace them 
immediately.

 

Only use the test lead provided with the equipment or 

UL Listed Probe Assembly rated CAT IV 1000V or better.

Disconnect the test leads from the test points 
before changing meter functions. 

This  Clamp-on  meter  is  designed  to  apply  around  or  remove  from 
uninsulated hazardous live conductors. But still, individual protective 
equipment  must  be  used  if  hazardous  live  parts  in  the  installation 
where measurement is to be carried out could be accessible.
