2Description
2.1 Overview
Any electrical equipment can be subject to electrostatic discharges from human operators or from adjacent objects.
The electrostatic discharge simulator ONYX, reproduces this phenomenon to evaluate the performance of electrical
and electronic equipment.
There are specific test requirements that must be satisfied when conducting ESD testing. These are noted in some
detail in IEC/EN 61000-4-2, ISO 10605 and other standards.
Because of its modular design, ONYX can be adapted quickly and easily to perform testing to any ESD standard.
All ESD testing should ideally be conducted in a Faraday cage or other suitable enclosure.
For small EUT's, a test table constructed only of wood must be used, This is covered with a metallic horizontal
coupling plane which in turn is connected to a ground reference plane by 2 x 470 kOhm resistors.
The EUT should be mounted above the horizontal coupling plane on an isolation plate of 0.5mm thickness.
Vertical coupling planes are to be used to inject an ESD field into all four faces of an EUT.
Larger floor standing equipment must be treated in a similar way but have an isolation plate of 0.1 m.

5Local Operation
5.1 Power
5.1.1 Battery power & charger
The ONYX simulator comes together with two rechargeable NiMH batteries and a battery charger.
The battery has to be either removed from the ONYX to be charged, or charged while the ONYX is not in operation.
The battery charger cable has to be connected to the battery’s charging connector, located at the base (bottom) of the
battery, and has to be correctly and securely inserted to ensure correct charging.
The indicators on the charger provide all necessary information on the status of the battery and charging as described
below:
(1) LED red “Power”: Steady light indicates that the charger is ready for use
(2) LED red “Charge”: Steady light indicates the fast charging process after connecting the battery pack
(3) LED green “Ready”: Steady light indicated that battery is fully charged. After approx 2 minutes it switches to
flashing to indicate trickle charging.
Once the battery pack is connected, the testing cycle is initiated and the green LED flashes for approx 1 minute. If
it carries on flashing and the red LED “Charge” does not light, it indicates that the battery pack is not connected
properly and maybe has an incorrect polarity
(4) LED yellow “Discharge”: Steady light indicates the discharging process after pressing the yellow button. The LED
“Ready” flashes for around 1 minute indicating the testing cycle
(5) Discharge Button: Press this button for about two seconds to start the optional discharge process for the battery
pack. Normally it is not necessary to discharge the batteries before charging
Fig. 2 charger and battery pack
To avoid deep discharge, remove battery pack from ONYX when not using it for more than one month
To avoid deep discharge due to self-discharge, battery pack should be fully charged at least once within a
year, even if unit is not in use
5.1.2 AC mains adapter (optional)
The optional AC mains adapter set can be used for powering the ONYX
from the power mains. To power the ONYX, replace the battery pack by the
mains adapter and connect it to the power supply output cable.

5.2.5 Discharge tips
Before touching the discharge tips to change them, switch the ONYX tester off and wait for a few
seconds so that the impulse capacitor can discharge internally.
Do not touch the tips while the “HVon” is displayed on the touch screen, indicating that the capacitor
is charged. Any contact with the test tips during this stage will result in electrostatic discharge.
The ONYX simulator is supplied with one contact and one air discharge tip. Additional tips such as 30mm air discharge
and fast rise time tips are available as an option.
The 30mm air discharge tip ensures a more stable rise time of the pulse above 15kV.
The fast rise time tip reduces the rise time of the ESD pulse down to 0.3ns.
Please refer to section "Accessories and Options" for ordering details.
Because of the sharp edge of the contact discharge tip, we highly recommend that you handle this
part with care to avoid unnecessary injuries.
