XS series operating manualXS user manual v0.55 - 31 -PRODUCT OVERVIEWThe XS series is a range of units performing very easily insulation resistance measurements, dielectricstrength tests and ground continuity tests.The RXS50/56 and RXS500/506 are dielectric strength testers under 50VA or 500VA and the DXS50/56and DXS500/506 are dielectric strength testers under 50VA or 500VA including a megohmmeter, andthe SXS50/56 and SXS500/506 include all the above functions plus a ground continuity function. TheSXS16 also includes all three functions, but the dielectric strength test function and the megohmmeterfunction are specific.The XS series makes possible to perform insulation resistance measurement, ground continuityresistance measurement and dielectric strength test on a various number of insulating material as resin,porcelain, oil, plastic as well as on final products such as capacitors, transformers, switches, cables,connectors or on devices connected to the main or supplied by batteries. The instruments allow groundcontinuity measurement fitting most part of the existing standards regarding measuring and medicalfields, office devices, machinery,...The XS series is fitted with a high resolution liquid crystal display (LCD) and a keyboard allowing an easyuse. A single output for the dielectric strength tests and the insulation resistance measurements makeseasy the connection on the specimens. Red and green LED lamps indicate visually and without anyconfusion the tests results.The dielectric strength tests are performed under adjustable voltages from 100 VAC up to 5000 VAC ( upto 6000 VDC for the XS56 and XS506 models) by XS devices other than the SXS16, which can performdielectric strength tests under voltages from 100VDC and 10000VDC. The short circuit current is 10mA for 50VA models, 200 mA for 500VA models, and less than 1mA for SXS16. The breakdownvoltages and currents are memorized on the display after breakdown detection and voltage cut off.The insulation resistance measurements are performed under voltages from -10 up to -500VDC (-20 to-1000VDC with option 26) for XS devices other than the SXS16. The SXS16 performs the resistancemeasurement under voltages from +500 up to +1500VDC. The XS unit indicates in a direct reading withunity display, the resistance values from 50 k up to 200 G (2 T in option ), except the SXS16 whichgives values from 1MΩ to 20GΩ.The ground continuity resistance measurement is performed under current from 5 to 32A AC with opencircuit voltages of 6 or 12V AC. The XS unit indicates in a direct reading with unity display, the resistancevalues from 1mto 1500m.RS232C serial interface comes as standard with the XS series and in option, the unit can be equippedwith PLC input/output interface or with a IEEE488 or ETHERNET interface enabling a full remote controlby a PC computer.
