Dielectric Strength Function (hipot)

Voltage range :100 ... 5 000 VAC / 100 ... 6 000 VDC - Positive pole connected to bond in DC

Voltage generator accuracy:± (2 % + 5 V) over full voltage range and with a current below 100 μA

DC voltage ripple< 1% with a current < 100 μA

Max D.U.T. capacitance< 1μF (discharge time < 10 sec.) Discharge resistor in DC = 1,5 MΩ

Voltage measurement accuracy:Through a kilovoltmeter directly connected to output. ± (1,5% + 5 Volts) resolution: 600 pts

Short-circuit max. current< 20 mA AC / < 20 mA DC

Default detection modes

Current variation ΔI / Max-Min current / without detection

ΔI detection mode current range:Adjustable from 1 mA ±10 % to 10 mA ± 10% by 1 mA steps, pulse 10 μS ±20 %.

Min/Max detection mode current range:adjustable from 0,001 mA to 9,999 mA by 0,001mA steps

Permanent total current measurement

Resolution 9 999 pts with a shunt installed in the test circuit

Total current accuracy :(in AC and DC)0,001 mA à 9,999 mA ± (2 % + 3 μA)

accuracy in DC with a load > 1 MΩ 10,00 mA à 20,00 mA± (2 % + 0,05 mA)

PERMANENT mode

The rise duration set is active. The output voltage rises to the setpoint. Test stops if there is a fault or if pressing the red button on the front panel.

MANUAL mode

No rise time is set. Manual control pressing up and down arrows on the touch-screen. Test stops if there is a fault or if pressing the red button on the front panel.

AUTO mode

Test runs in 3 sequences : linear raise up to set voltage (Ramp Up), set output voltage remains applied (Dwell), progressive descent to 0V (Fall)

Ramp Up - Dwell - Fall duration :0,1 à 9999,0 sec. by steps of 0,1sec, accuracy +/- 20 msec.
