  • Page 9: Discharging Time (Dit)

    Discharging time can be set from 5 to 900 seconds. Default factory setting value is 120 seconds compatible with ETI capacitors type LPC. Default setting is optimal for capacitors with built in discharge resistors, without using extra discharge resistors or inductors. For PFC systems that have provided extra discharge resistors or inductors, which ensure quick discharge of capacitors, dit time can be much lower, but not less than 60s.

    alarm will appear on the display. Another pressing the button SET will cancel shown alarm. If more alarm events happened, another event symbol will appear on the display. By keeping the same procedure, it is possible to follow till last alarm event is not cancelled. In the displayed values mode it is possible to find out which values of alarm events activated alarm.
