DL9120 / DL9130        

                                           Operating Instructions 

- 23 - 

 

The  2  wire  mode  is  disabled  for  Three  Phase  Line 
Impedance tests. 

 
Rotate the rotary switch until Ze/Zs High is selected. Functions keys F1-
F4 have are used to select the options below: 
 

F1 

F2 

F3 

F4 

L-PE loop/ 

L-N loop 

select 

 

Z Max 

 

Not used 

 

Z Auto Start 

 

Note:  When  the  Ze/Zs  High  switch  position  is  selected,  the 

DL9130EV  will  default  to  the  last  used  setting,  even  if  it  has 
been switched off.  

 
Auto Start (F4)  

When Auto start is activated the Z Auto icon is shown on the display. Loop 
measurements will automatically start approximately 3s after the DL9120 
/ DL9130EV is connected to correct mains supply via a mains plug or the 
test probes. The Auto Start function remains enabled if the switch position 
is changed or the DL9120 / DL9130EV is powered off. To disable the Z 
Auto Start function press F4.  
 

Note:  If  the  mains  supply  is  removed  within  the  Auto  start 

countdown period the test will not start.  

 

TEST 

To begin the test, press and release the TEST key or select Auto Start 
using F4.   
 
When  the  test  is  complete,  the  measurement  is  shown  in  the  primary 
display  and  the  calculated  Prospective  Short-circuit  Current  (PSC)  is 
shown in the secondary display.  
 

5.8  Non trip Earth Loop Impedance / Line Impedance 

 

 

The  DL9120  /  DL9130EV  will  only  allow  the  Earth  Loop 
Impedance test to be performed if the correct voltages are 
detected between line-earth (L-PE illuminated), line-neutral 
(L-N illuminated) and neutral-earth (N-PE 

not

 illuminated). 

   

 

The DL9120 /  DL9130EV can only perform Non trip Earth 
Loop  Impedance  tests  if  the  neutral  resistance  is  <10R. 
Should  the  neutral  resistance  be  above  10R  then  the 
DL9120 / DL9130EV will display the 

Hi-N

 error.
