FeatureAchieve more reliable test!
Equipped with "3 Pre-check Functions"
The new ESD simulator is equipped with 3 pre-check functions; "high voltage power output check", "insulation failure check", and"discharge relay operation check" on the main body and discharge gun.You can prevent troubles such as failing to perform the test properly;
if you did not notice the failure of the tester body or the relay inside the discharge gun has reached the end of its life.

Pre-check completed!

① Set the discharge gun in the gun holder.
② Press the [START] key on the tester.

③ Bring the discharge gun into contact withthe pre-check terminal [PRE CHECK] andpull the gun trigger.

[Check 1] High-voltage power output check: Check the error from theset value.
[Check 2] Insulation defect check: Checks for defective insulation
withstand voltage.

[Check 3] Discharge relay operation check: Check the relay for wear.
Check the wear of the discharge relay by bringing the discharge gun into contact
with the check terminal and discharging.

When the discharge gun is placed in the attached gun holder, you can check the outputof the high-voltage power supply and check for insulation defects.

ESS-S3011A & GT-30RA
The discharge gun became lighter and easier to use
The discharge gun itself has been reviewed from scratch to achieve weight reduction and the best balance of the center of gravity.
The weight is lighter than previous one and the balance of the center of gravity has been improved, making it extremely easy to hold andreducing the burden on the arm during long-term tests. Please pick it up and try it.
In addition, it is now to easy to confirm the performing of air discharge by the LED indicator on the top of the discharge gun,which was possible only by visual check before, making it difficult to confirm at times. Also, it is a discharge gun with a full rangeof functions and operations, such as easy replacement of the CR units and discharge cup, which used to take time and effort, and theinstallation of an "LED light" that brightly illuminates the application.

Equipped with an LED light that illuminates
the application location.

ESS-801 / 801GL
FeatureESD test environment in conformance with EN/IEC61000-4-2 Standard.
Two types for EUT are available, table-top type and floor-standing type so that the environments can support the tests along EUT figures. Since the table is made of wood,
influence to the test result should be small (quantitable test result can be expected since
the discharge can be realized in state high frequency electromagnetic field is less lost)
and the high reproducibility can be expected and realized. Also, can be versatilely
utilized for another tests like impulse noise immunity test, etc.

Micro-gap Discharge Tip MODEL : 12-00010A

Enabling a more stringent evaluation for
the real world ESD immunity
Connected to the NoiseKen ESD gun, this tip allows for a waveform with higher
peak amplitude and a faster rise time. It is a common view that ESD immunity testingis the most challenging and passing the standard test does not always assure realworld immunity. This tip is helpful for more extensive testing against non-standardized ﬁeld events

Direct discharge test : Contact discharge (at 1 second interval) and air discharge (at max. 5 sec. cycle)
Indirect discharge test : Discharge to VCP and HCP
At least 10 single discharges shall be applied at 1 second or longer interval in both positive and negative polarities.
* A preliminary test with discharges 20 times or more per second may be done in order to select the points to which single discharges should beapplied.

6. Evaluation of Test Results and Test Report
The tests results are classified into following 4 patterns according to specifications of EUT and operating conditions.
1) Normal operation within the tolerance of the specification
2) Temporary degradation or loss in the operation or the function which is able to be recovered by a self-recovery function
3) Temporary degradation or loss in the operation or the function which needs to be recovered by user intervention or resetin the system.
4) Damage of the system (parts) or software, and unrecoverable degradation in the function due to loss of the data.

Generally, as far as the EUT is immune to the ESD during testing and it satisfies the functional requirements according to the productspecification after testing, the test result can be perceived as "Pass"
The test report shall contain the test conditions and the result.

1. General
Electrostatic discharges which are generated both in vehicles and while we get on and oﬀ there can be factors to cause malfunction of the electrical devices and components. Nowadays, more attention has been paid, as vehicles install more and more electronic devices and components.
This Standard regulates that static electricity is discharged to the electronic devices or equipment from the charged human body and tests are
simulated by electrical circuit to reproduce the electric current waveform at the discharge.
In addition to procedures for the immunity tests and evaluations in state that the electronic devices or equipment work while the vehicle isdriving, the Standard also regulates tests procedures to evaluate the immunity of the each module against simulated human discharges during
the assembly process or in servicing.
