The high-voltage relays are consumable items. The electrical contacts in thehigh-voltage relays deteriorate with use and this can result in poor electricalconnections, contact welding, or insulation failure occurring during normal use.
If you experience problems such as being unable to apply a static discharge after
starting a test or a static discharge occurs as soon as a high voltage is output, thecause may be deterioration of a high-voltage relay. In this case, please contact yoursales agent or the Noise Laboratory repair and calibration center.
Do not attempt to repair the instrument yourself as this is very dangerous.

7–2.



Discharge Tip

The discharge tips are supplied with this product.
The discharge tips are consumable items. The surface of the discharge tip is being
worn away with repeating contacting and discharging.
In case of the contact discharge tip, especially, the sharp point of it becomes so dull thatit cannot pierce the insulation coating of EUT and a proper contact discharge test
cannot be conducted.
In such a case, it must be replaced. Noise Laboratory sells individual new discharge
tips.

7–3.



High Voltage Relay

CR Unit

The CR unit is attached to this product.
The CR unit is a consumable item. The characteristics of the CR unit is changing withrepeating discharge, and in some cases, capacitance or resistance can become out of

Before replacing the discharge tip, set the simulator to the stop state 〔STOP〕
Failure to comply with this rule may result in electric shock or injury.

Before touching the discharge tip, remove static charge
After an electrostatic test, the discharge tip may still be charged at a high voltage.
When replacing the discharge tip, remove any static charge (by making the discharge tip contact
the GND clip, etc.) before touching the discharge tip.

Types of Discharge Tips and Their Applications
There are three types of discharge tips, which are available as default, as shown in the following table.
They must be used differently, according to the applicable test standard and test method.

The round discharge tip tends to be unable to maintain a high voltage in an air discharge test
exceeding 15kV, due to natural discharging into the air.
To improve this, use the spherical discharge tip instead.

12. OPERATIONThis Operation Manual deals with the operation of Discharge Gun alone.
For operating procedures for the entire testing system, refer to the operation manual for the test
system to be used in combination.

12–1. Starting Test

Sufficient care must be taken during the test, as the voltage set in the simulator isgenerated.
Do not touch the discharge tip and discharge cup, as they are charged at a high voltage.
Failure to comply with this rule may result in electric shock or injury.

Take care to ensure there are no other people close to the electrostatic testing
environment, and that all necessary preparation for the test has been carried out.
Failure to comply with this rule may result in electric shock or injury.



The twisted cable must be repaired.
Don’t use or keep cable when it is twisted. There is possibility that cable is disconnectedinternally.

1) When the simulator is started 〔START〕, a high voltage is output from the high-voltage output
connector of the simulator and the status display lamp on the discharge gun is turned on in red.
2) Execute a test by operating the trigger switch.
3) If the discharge detection function is turned on, the status display lamp changes from red to green,
when a discharge is detected. The discharge detection function is valid only in air discharge mode.
Status display lamp

Trigger switch

Figure 12.1 Status Display Lamp
If the status display lamp is not turned on by starting a test 〔START〕, check the following.
 Make sure that the high-voltage output connector of the simulator is connected to thehigh-voltage input connector of the discharge gun correctly.
If the display lamp remains turned off even after checking the above, the instruments may be
faulty.
In this case, contact your sales agent or the Noise Laboratory.

12. OPERATION

The trigger switch of the discharge gun is enabled, when the trigger setting of the simulator’s
main unit is set to 〔GUN〕.

12–2. LED Light
During the test, the light can be used for irradiation by enabling the LED light function 〔ON〕.
When the main unit of the simulator is started, the LED light is turned on.

Figure 12.2 LED Light

With NoiseKen’s previous simulator models such as ESS-2000AX, the LED light cannot be
turned on.

12–3. Stopping a Test

Temporary stop by the trigger switch does not set the 〔STOP〕 state.
This is dangerous, because the unintentional trigger operation may restart the electrostatic
discharge. Unless the test is to be resumed immediately, press the 【STOP】 switch on thesimulator.
Failure to comply with this rule may result in electric shock or injury.

Before touching the discharge tip, remove static charge
After an electrostatic test, the discharge tip may still be charged at a high voltage.
When replacing the discharge tip, remove any static charge (by making the discharge tip contact
the GND clip, etc.) before touching the discharge tip.

1) In the contact discharge mode, pressing the trigger switch again during discharging can stopdischarge temporarily.
In the air discharge mode, since electrostatic discharge cannot be discharged without pressing thetrigger switch, this pause function by pressing the trigger switch is not available.

2) To stop the test, press the 【STOP】 switch on the simulator.

15. ABOUT AIR DISCHARGE
15–1. ESD Testing to the IEC standard
The IEC 61000-4-2 standard defines CONTACT and AIR discharges. These two methods are different
phenomena requiring the different ESD test circuit operations. Be aware that, in particular, the air
discharge method is ambient (temperature and humidity) sensitive.
In contact discarge mode, test results are consistent and are rarely affected by the ambient.

15–2. IEC standard requirement for an ESD generator for the air discharge method
The IEC 61000-4-2 standard defines “holding time”. Holding time is an interval of time within which thedecrease of the test voltage due to leakage, prior to the discharge, is not greater than 10%. The standard
requires ESD generators have >5s holding time.

15–3. ESD test circuit operations in the air discharge mode
An electrical schematic of the ESS ESD simulator and a compatible gun is show in Figure 15.1
① High voltage supply (A) charges the energy storage capacitor (C) through charge relay(RL1) and charging resistor (R1)the status where the START key on the ESS base unit has been pressed② When charge relay (RL1) turns off, and discharge relay (RL2) turns on, the discharge tip(B) has an equal voltage to charged capacitor (C)the status where the TRIGGER key has been pressed and held
③ Approach the discharge tip to the EUT as quick as possible.
The discharge tip shall touch the EUT surface irrespective of whether a discharge
occurred or not④ The holding time requirement shall be met between the above steps 2 and 3.
 In actual testing, there is no need to have a 5 second interval between step 2 and
3.

B：discharge tip15–4. Charge leakage in the air discharge mode
As described earlier, the charge relay (RL1) turns off at an instance when the Trigger of the discharge
gun is pressed, the charge stored in the storage capacitor (C) starts leaking. The discharge gun has afinite insulation resistance value but not the ideal value (∞Ω). Therefore, this leak cannot be avoided.
Since the insulation resistance is high within a range of 1013Ω to 1016Ω, the ambient environment(especially, humidity) and stains or dirt on the surface easily lower this value and cause a risk of not
being able to meet the holding time requirement. Generally, in a high humidity environment, whichcontains much moisture and thus causing much moisture on the surface of the insulating materials, theinsulation resistance gets lower. For this reason, keeping the surface clean is indispensable for a better
performance of the gun. Generally, clean surface maintains a higher insulation resistance while dirty or
stained surface has a lower resistance.
For the recommeded cleaning procedures for the GT-30R series discharge gun, refer to Chaper 16.
Cleaning Proceures. Periodic cleaning is recommeded to keep the gun clean.

15–5. Air discharge testing and humidity
In many cases, the air discharge testing is accompanied by an air discharge. Air discharge is an event
where air breakdown occurs and current flows in the air. So, air discharges are strongly affected by theatmospheric conditions. The discharge path has a resistance and the longer the path is, the higher the
resistance is.
① Higher humidity
the atmosphere contains more moisture, air discharges are easier to occur.
 Generally, relatively a long discharge path causes a lower peak current andslower rise time
② Lower humidity
the atmosphere contains less moisture, air discharges are difficult to occur.
Generally, relatively a short discharge path causes a higher peak current andfaster rise time37

15–6. Temperature/humidity requirement
The IEC 61000-4-2 standard specifies the climatic conditions where air discharge testing is permitted.
Ambient temperature :15℃～35℃
Relative humidity: 30%～60%
The figure 15.2 (below) shows the ambient temperature, relative humidity and moisture contents in air(absolute humidity, in g/m3 ）.

Ambient temperature, relative humidity and water contents (absolute humidity, in g/m3 ）.

As shown in the above figure, the absolute humidity values have 6 times difference from the lower (15℃
／30% ) to higher (35℃／60%) limits even within the range specified by the IEC 61000-4-2 (the centerzone of the figure). Testing in a high absolute humidity environment may be under testing, as testing isdone with a long discharge path and therefore, a lower peak and slower rise time current waveform, thus
containing less high frequency components. Another side effect is that a long discharge path leads to low
reproducibility due to inconsistent discharges. For these reasons, air discharge testing shall be done
preferably in the lowest possible absolute humidity environment.

The ISO 10605 standard covering automotive electronics states the preferable relative humidity
range is from 20 to 30% while it sets a allowable range of 20 to 60%

38

16. CLEANING PROCEDURES
16–1. CLEANING IS CRITICAL
Keeping the surface of the gun clean is indispensable for a stable operation with high voltage up to 30kV(the maximum output of the compatible ESS base units). Conduct periodic cleaning following the
instructions shown in Sections 2 and 3 of this chapter.
Cleaning maintains a higher surface resistance and no humid contamination is observed. The clear
surface reduces the effects of ambient humidity and enables stable and consistent discharges.
The dirty or stained surface has a lower surface resistance and is susceptible to humidity, leading tounstable and irreproducible tests.

16–2. Area to be cleaned
For the GT-30RA series discharge gun, the parts circled by lines as show in the Figures shall be cleaned.
The areas circled by dotted lines require cleaning. The areas circled by solid lines require intensive
cleaning.
① Surface of the body cover and discharge cup

Discharge cup shall be
intensively cleaned.

Cleaning not required for the area into
which you cannot insert your fingers.
② Surface of the CR unit

Cleaning not required for this side (the outside when
the CR unit is installed onto the discharge gun)39

16–3. Cleaning method
Use the following :Anhydrous alcohol (Anhydrous ethanol) : (ethanol >99.5vol%).
Waste cloth: unused, and the type which does not easily generate paper dust and fiber remaining(disposable paper cloth recommended)
Apply Anhydrous alcohol to a waste cloth and wipe the target parts.

Do not use neutral detergents.
Neutral detergents contain surfactants, which make water absorbing hygroscopic film over thesurface of wiped parts. Ambient moisture may affect tests.

16–4. Cleaning interval
Conduct cleaning, each time the gun is used. Especially, in a high humidity environment, cleaning ishighly recommended.
