XS series operating manual 
 
XS user manual v0.55  - 47 - 
IMPORTANT: 
 
 
In  the  REMOTE  TRIG.  mode,  the  unit  will  stop  the  measurement  but  will  not  display  any 
SAFETY LOOP open message. 
 
If you have selected the REMOTE TRIG. mode and if the connections 1-9 and 2-10 are already done 
when selecting a measurement function (Megohm,Hipot, ….), the following message is displayed  
 
        INPUT ERROR 
 
and the REMOTE TRIG. mode is automatically removed.  
Please refer to the above procedure to select correctly the REMOTE TRIG. mode. 
 
 
Interface selection  
 
 
The XS series units can be remote controlled by the following interfaces: 
 
RS232, IEEE 488 (GPIB), ETHERNET et par  interface API. 
 
At the same time, only one interface can be selected  
If an interface is not installed in the unit, its selection displays an error message: OPTION MISSING. 
 
For more details about those interface capability, please refer to the related section of this manual. 
 
 
Sequence selection (Option 04) 
 
For DXS models only, if the option 04 is installed, this function allows to to perform automatic 
cycling of the megohm and dielectric strength functions. 
Display on the LCD screen the various sequence modes with the UP and DOWN arrows : 
 
      OFF,M+H,H+M,M+H+M,..... 
 
The M letter shows an insulation resistance measurement and the H letter shows a dielectric 
strength test. Operating the sequence mode is recalled in the measurement windows by the 
following drawing symbol:  
 
 
 
 
 
In  a  M+H  sequence  the  unit  performs  first  an  insulation  test  and  then  a  dielectric  test.  It  is 
necessary to set the parameters specially the test times before running a sequence. In case of a 
fault during the test, the sequence is stopped. When operating in sequence mode, at power on, 
the  first  sequence  function  type  is  automatically  selected.  When  attempting  to  trigger  the 
measurement mode in a function type which is not the first one of the sequence, the following 
message is displayed: 
    SEQUENCE ERROR 
Escape of the function and select either another function or another sequence mode.
