XS series operating manualXS user manual v0.55 - 42 -Beep on FAIL configurationWhen a test result is failed, a permanent audible signal is emitted by the unit until the removal bypressing on the [DISCHARGE] key. This function is active when YES is selected and not activewhen NO is selected. The choice is memorized after switching off the unit.Filtering configuration for capacitive specimenThe FILTER function select a special operating mode of the unit when testing on capacitors or onspecimens with a certain among of capacitance (cables,…).Display the required mode with the UP/DOWN arrows: NORMAL, CAPACITOR, R.H.TIME..., thenenter.Fig 6.3(mode) CAPACITORThe CAPACITOR mode allows to perform stable insulation resistance measurements oncapacitive specimens (reel of cable, capacitors,...). During dielectric strength test with a DCvoltage, the CAPACITOR mode inhibits the voltage adjustment to avoid over voltage, switches the1.5 Mohm discharge resistor at the beginning of the fall time and controls the residual dischargevoltage until this one is lower than 100 volts. Operating this mode is recalled by the drawing of acapacitor over the unity display in the measurement menus.(mode) R.H.TIME ( Real Hold Time )The R.H.TIME (Real Hold Time) mode improves the operation of voltage ramp during the dielectricstrength tests. It is suitable for tests using a DC high voltage on capacitive specimens. At the endof the rise time, the unit controls the output voltage and triggers the hold time only when thevoltage has reached the pre-set value. During the fall time, the unit stops the measurement cyclewhen the output voltage is lower than 30 Volts.(mode) NORMALThe most common mode: linear rise and fall time ( t< 3 sec.) with automatic test voltageadjustment at the end of the rise time.
