  WARNING 

 

● 

Do not make measurements of power lines carrying more than 250V.                 
IN SOME CASES, POWER LINES MAY CARRY VOLTAGE SPIKES OF 
SEVERAL TIMES OF THE NORMAL SUPPLY VOLTAGE.                             
THIS INSTRUMENT SHOULD BE USED TO MEASSURE POWER LINES. 
*The terms of “POWER LINE” means the electrical circuit providing the power 
to factories, buildings, etc. 

● 

Before  operating  this  instrument,  familiarize  yourself  with  all  instructions 
outlined in this manual. 

● 

Always check to make sure that the function switch is set to the proper position. 

● 

When  making  measurements,  use  CAUTION  as  dangerous  voltages  may  be 
present in normally safe areas. 

● 

To avoid electrical shock, use CAUTION when working above 60V DC or 25V AC 
rms. 
Such voltages pose a shock hazard.   

● 

Never make measurements with the case opened. 

● 

Never fail to keep the maximum tolerable input. 

● 

Never  operate  this  instrument  if  it  becomes  wet,  damp  or  has  any  liquid 
condensation build-up on any part of the instrument. 

● 

Never make measurements for uninsulated conductors or bus bars.
