FUNCTION
Output voltage
— 0 to 5 kV AC ( 50 or 60 Hz) .
Limited to 4.2 kV AC with FMG501
— 0 to 6 kV DC ( RXS56, RXS506)
— Accuracy: ± ( 2% + 50 V) ( RXS50) and
± ( 3% + 50 V) ( RXS500) of the preset
value between 100 to 5000 V and for
a current < 100 ¼ A ( RXS50) and
< 1 mA ( RXS500) with the detection
modes: DI, IMAX or DI+ IMAX
Voltage reading
— On a digital kilovoltmeter connected
on the output terminals

— Display: 600 digits
Stability
— Less than 1% for a mains variation of
± 10% ( RXS50)
— Less than 3% for a mains variation of
± 10% ( RXS500)

Short circuit < 13 mA AC ( RXS50/ 56) and
200 mA AC ( RXS500/ 506)
and > 20 mA DC ( RXS506) for the max.

Breakdown detection
.“ DELTATEST� detector adjusted for
DI = 1 mA ± 10% ( RXS50) and DI = 10 mA
± 10% ( RXS500) with 10 µ sec. ± 20% .
Total insensitivity to current due to the
resistance and the capacitance of the
device under test
.“ IMAX� detection by maximum current
adjustable from 0.01 to 10 mA, by 0.01 mA
steps ( RXS50) and from 0.1 to 110 mA by
0.1 mA steps ( RXS500)
.DELTATEST and IMAX mode combination

IMIN threshold function
.Detects whether the probe is properly
connected to the specimen under test
.Adjustable from 0.01 to 10 mA ( RXS50)
and from 0.1 to 110 mA ( RXS500)
DC voltage ( RXS56, RXS506 models)
.Positive pole grounded
.Ripple < 1% for I < 100 µ A ( RXS56) and
I < 1 mA ( RXS506)
Breakdown indication
.By visual ( LCD screen and LED) and
sound signal
.Breakdown voltage and current are
stored on the LCD display
.HV primary transformer shorted when
the output voltage is switched off
Timer
