After pressing the main switch, press the EXIT key. This places the simulator in the initial menu, which
displays three operational modes, trigger selection and utility.
If you desire to operate the unit in the manual mode, press the corresponding function key. The
parameters to be set by the operator will appear. Discharge method (contact/air discharge), discharge
voltage, number of discharges and interval can be set. Select the parameter by pressing the
corresponding function key then the value can be altered by the Increment or Decrement key.
Contact discharges: For contact discharge testing, after completion of required settings, press the
START button and pull the trigger. The simulator will then generate the required number of pulses at
the required interval. Pulling the trigger again will pause the unit. Pulling again will restart the unit.
Air discharges: For air discharge testing, after completion of setting, press the START key. To carry
out air discharges, pull and hold the trigger to maintain the HV relay in the on status and approach the
discharge tip to the EUT.
When the SWEEP function is active, the simulator generates discharges in an automatic voltage ramp.
The initial, fi nal and step voltages can be freely set. In this mode, the number of discharges set is that
in each step. For example, when the simulator is set to 5kV for the initial voltage, 10kV for fi nal voltage
and 1kV for step voltage, in a way of 10 discharges at an interval of 1 second, it produces 10 pulses at
5kV at an interval of 1 second and proceeds to 6kV pulses, also 10 discharges. These steps continue
until the simulator has completed 10 pulses of 10kV.
Two different ways of pulling the trigger: When the trigger is pulled and then released quickly, the
simulator operates in a way that it pauses before it proceeds to next step voltage. For continuous
operation, pull the trigger for more than 2 seconds. A sign of "CONTINUE" is indicated on the screen
and the simulator runs a complete step ramp test without further operator’s trigger.
The four test levels are preset. Select the desired level and run a test.
The simulator can store up to 99 tests including Sweep settings. Each test is given a number (called
Unit No). Any combination of units selected from 99 tests in the Manual Mode can consist of one test
sequence having 30 units maximum. Twenty test sequences can be stored. For a unit setting, press
EDIT button. Settings of voltage, etc. can be done in the same way as in the Manual mode.
