Beep on FAIL configuration
When a test result is failed, a permanent audible signal is emitted by the unit until the removal by
pressing on the [DISCHARGE] key. This function is active when YES is selected and not active
when NO is selected. The choice is memorized after switching off the unit.
Filtering configuration for capacitive specimen
The FILTER function select a special operating mode of the unit when testing on capacitors or on
specimens with a certain among of capacitance (cables,…).
Display the required mode with the UP/DOWN arrows: NORMAL, CAPACITOR, R.H.TIME..., then
enter.

(mode) CAPACITOR
The CAPACITOR mode allows to perform stable insulation resistance measurements on
capacitive specimens (reel of cable, capacitors,...). During dielectric strength test with a DC
voltage, the CAPACITOR mode inhibits the voltage adjustment to avoid over voltage, switches the
1.5 Mohm discharge resistor at the beginning of the fall time and controls the residual discharge
voltage until this one is lower than 100 volts. Operating this mode is recalled by the drawing of a
capacitor 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 dielectric
strength tests. It is suitable for tests using a DC high voltage on capacitive specimens. At the end
of the rise time, the unit controls the output voltage and triggers the hold time only when the
voltage has reached the pre-set value. During the fall time, the unit stops the measurement cycle
when the output voltage is lower than 30 Volts.
(mode) NORMAL
The most common mode: linear rise and fall time ( t< 3 sec.) with automatic test voltage
adjustment at the end of the rise time.
