 Resistance,   Continuity, nS Conductance functions 

Press  the 

SELECT 

button  momentarily  to  select  the

 

subject  functions  in  sequence. 

Last selection will be saved as power up default for repeat measurement convenience.  
 

 

Note:  
Conductance  is  the  inverse  of  Resistance,  that  is  S=1/

  or  nS=1/G

.  It  virtually 

extends  the  Resistance  measurements  to  the  order  of  Giga-Ohms  for  leakage 
measurements. 
 

 Continuity function  is  convenient for  checking  wiring  connections  and  operation  of 

switches. A continuous beep tone indicates a complete wire. 

 
CAUTION 

Using resistance and continuity function in a live circuit will produce false results and 
may  damage  the  instrument.  In  many  cases  the  suspected  component  must  be 
disconnected from the circuit to obtain an accurate reading
