12  MAINTENANCE AND FUNCTION CHECK 

12.1  General 

 

Inside the test system there are no adjustable elements accessible to the user 

neither for calibration nor for maintenance purpose. 

The housing of the test system must not be opened (except for SW update via SD-card). Should any 
maintenance or adjustment become necessary, the whole test system, together with an order or fault 
report, should be sent to a Teseq service center. 

Maintenance by the user is restricted to cleaning the outer housing, performing a function check and 
verify cation of the pulse parameters. 

 

12.2  Cleaning 

In  general,  a  moist  cloth  is  sufficient  for  cleaning  the  outer  housing,  including  the  touch  panel.  If 
necessary add a small amount of a mild, non-foaming household cleanser. 

No chemicals (acid, etc.) should be used for cleaning purposes. 

Before beginning to clean the test system ensure that it is switched off and the mains power cable is 
unplugged from the supply. 

12.3  Function check 

 
As soon as the test system is switched on the Power-LED should light up. If this is not the case then 
please  check  the  mains  power  connection  to  the  test  system  as  well  as  the  fuses,  voltage  selector 
and any other cabling. 

The instrument automatically carries out a diagnostic routine once it has been successfully switched 
on. 

The generator cannot perform any test while the interlock circuit is open. 

Pulse  generation  can  be  observed  at  the  output  connectors  by  means  of  an  oscilloscope.  This  is  a 
practical way to check that the system is functioning correctly but should never be used for reference 
or calibration purposes. 

 

 

Do  not  connect  the  oscilloscope  directly  in  order  not  to  exceed  its  max.  input 
voltage. 

Teseq  recommends  the  use  of  a  HV  differential  probe  type  with  adequate  input 
range. 

12.4  Calibration 

The combination of high voltages and high frequencies in a single pulse makes the calibration of EMC 
pulse  generators  particularly  demanding  and  difficult.  Teseq  has  one  of  the  few  accredited  test 
laboratories in Europe that is in the position to undertake calibrations in this specialized field.
