Dielectric strength test error messages  
 
The following error messages may appear during the measurement: 
 
 
(message) SAFETY LOOP 
 
the safety  loop is  not  closed.  There is  no connection  between the  points 1-9 and  2-10  of the C5 
connector of the rear panel. Make the connection, press again on the [MEASUREMENT] green push 
button to trigger the measurement mode. 
 
 
(message) VOLTAGE ERROR 
 
the test voltage has not reached its final value (impedance of the specimen under test too low), in DC 
voltage wait for the end of the charge, in AC voltage check with the current specifications of the power 
supply. In case of over heating a built-in thermal switch cuts off the high voltage generator.  
Wait for 3-5 minutes before going on. 
 
 
(message) I<IMIN 
 
during the HOLD time, the leakage current flowing through the specimen under test has not reached 
the minimum value set by the IMIN parameter (possible bad connection of the test probe). This fault 
gives a bad (FAIL) test result even there is no breakdown. 
 
 
(message) SYNCHRO ERROR 
 
the dielectric strength test board is not able to generate the sinusoidal signal which drives the HV 
transformer.  
You cannot perform a test, get in contact with our Service department (+33 1 64 11 83 48) 
 
 
(message) BOARD NOT READY 
 
the microprocessor board cannot communicate with the insulation resistance board.  
You cannot perform a measurement, get in contact with our Service department (+33 1 64 11 83 48)
