SAFETY INFORMATION

The following safety information must be observed to ensure 
maximum personal safety during the operation of this meter:

 

Do  not  use  the  meter  if  the  meter  or  test  leads  look 
damaged,  or  if  you  suspect  that  the  meter  is  not 
operating properly.

Never  ground  yourself  when  taking  electrical 
measurements.  Do  not  touch  exposed  metal  pipes, 
outlets, fixtures, etc., which might be at ground potential. 
Keep  your  body  isolated  from  ground  by  using  dry 
clothing,  rubber  shoes,  rubber  mats,  or  any  approved 
insulating material.

Turn  off  power  to  the  circuit  under  test  before  cutting, 
unsoldering,  or  breaking  the  circuit.  Small  amounts  of 
current can be dangerous.

Use caution when working above 60V dc or 30V ac rms. 
Such voltages pose a shock hazard.

When  using  the  probes,  keep  your  fingers  behind  the 
finger guards on the probes.

Measuring  voltage  which  exceeds  the  limits  of  the 
multimeter  may  damage  the  meter  and  expose  the 
operator to a shock hazard. Always recognize the meter 
voltage limits as stated on the front of the meter.

Never  apply  voltage  or  current  to  the  meter  that 
exceeds the specified maximum:
