EM Test esd NX30
Instruction Manual V 1.00.7 10 / 33
• High voltage generation is dynamically controlled by the processor. Varying load conditions, supply voltages, etc.
can thus be taken into account and have no effect on the pulse parameters.
• The instrument switches itself off automatically if it is not used for a while. The pulse parameters and operating
mode remain stored and ready for re-use.
• The charge voltage to the network is kept constant as long as the trigger is active. The high voltage is discharged
internally when the trigger is reset.
• If no discharge occurs when set for an air-discharge and the trigger is active, the processor waits for about 30 s
then autonomously resets the trigger and discharges the network internally with simultaneous acoustic warning.
• Pulse triggering is monitored. Once an arc has occurred the network is discharged internally so that no further arc-
ing is possible.
4.1.3 Operating elements
Apart from the trigger button itself (pulse triggering), all the operating elements, test-relevant setting and user information are
presented on the touch-sensitive display panel facing the operator.
The esd NX30 is switched on and off with the main power switch. The significance of the elements in the display field can be
seen in the following picture. Further information can be found in section "Operation".
All operations are performed via the touch-panel.
This is an example of a display shown on the panel when the pistol is switched on.
The function of the trigger button on the handgrip depends on the operating mode currently selected:
• As a pulse button in single discharge mode (1 pulse each time it is pressed).
• As an on / off switch in repetitive mode (discharges while button is pressed).
• As a pausing on / off switch in repetitive mode with the preset counter in operation (starts the discharges by press-
ing the button and stops the discharges by pressing the button again).
The remote control facility replicates the action of the trigger button by means of appropriate control signals.
4.2 System components
The basic set is packaged in a practical carrying case and comprises:
• Carrying case (esd NX30 only)
• ESD simulator esd NX30 consisting of pistol and base station with battery power supply
• Discharge network 150 pF/330 Ω to IEC / EN 61000-4-2 and ISO 10605
• 1 each air and contact discharges tips
• Battery charger / mains power pack
• Pistol stand (esd NX30 only)
• Operating instructions
This set contains all the items necessary under normal conditions to conduct tests conforming to the IEC / EN 61000-4-2.
