Resistance Measurement 

Function: 

Resistance Measurement 

 

The following picture displays the active terminals:

M a x   6 0   V       ,   3 0   V       ,   1 0 0   m A

The  two  leftmost  terminals  are  used  in  2-wire  systems.  MC4 
automatically  checks  the  connection  and  displays  the  found  wiring 
system  (2-wire,  3-wire  or  4-wire)  in  the  upper  right  corner  of  the 
measuring window. For more information concerning wiring options, 
see

  Resistance  and  RTD  Measurement,  Connections

  on  page 

118. 

 

Note. 

If  the  measured  resistance  value  is  infinite  or  very  high  (>  4000 
ohm), the text "+OVER" is displayed in the measuring window. This 
means  that  the  circuit  is  broken  or  the  connection  is  wrong. Wrong 
connection  may  also  cause  erroneous  reading,  typically  too  low.  If 
necessary,  use  the  2-wire  ohm  measurement  to  check  the  wiring 
before final connection.
