Achieve more reliable tests 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,  if you did not notice the failure of the tester body or the relay inside the discharge gun had reached the end of its life, you could not perform the test properly in the past!


[Check 1] High voltage power output check. Check the error with the set value. [Check 2] Check for poor insulation. Check for poor dielectric strength.When you place the discharge gun in the attached gun holder, you can check the output of the high-voltage power supply and check for poor insulation. [Check 3] Discharge discharge operation check. Check the relay for exhaustion.You can check the exhaustion of the discharge relay by bringing the discharge gun into contact with the check terminal and discharging.

In addition, you can check immediately with a simple operation by following the instructions of the tester with the pre-check function.

(1) Set the discharge gun in the gun holder. (2) Press the [START] key on the tester body. (3) Bring the discharge gun into contact with the pre-check terminal [PRE CHECK]. (4) Pull the gun trigger. Pre-check completed! In case of NG, a “FAILED” message is displayed.


 "CR constant indicator” to ensure correct attachment is in place

The constants of the discharge resistance and discharge capacitor, which were previously disassembled and checked, are now displayed on the main unit screen.
It is automatically recognized and the type is determined when the CR unit or discharge cup of the discharge gun is replaced, or when the power of this product is turned on, it is automatically recognized and the type is determined.
The CR unit and the discharge cup are identified separately, and if the combination complies with the standard, the conforming standard is displayed at the bottom of the main menu.

Is the discharge cup for IEC? For ISO? What are the values of charging capacitor and discharge resistance? Displayed on the main unit screen!

Discharge detection function that can check the presence or absence of discharge.

In the previous test, the presence or absence of discharge could only be confirmed visually, but the new ESD simulator is equipped with a discharge detection function.
When electrostatic discharge is performed, the presence or absence of discharge can be confirmed by the buzzer sound of the tester body and the LED of the discharge gun. 

Item/Status When discharge When non-discharge
LED display

Red → Green

Red (remain)
Buzzer sounds Short sound "Pip" No sound
Count Count up Trigger input → No discharge count

Achieves improved weight balance and weight reduction! Easy-to-hold and easy-to-use discharge gun!

“Improved balance of center of gravity and reduced weight by about 20%”
Of course! It is compatible with existing  ESD generators.

In a customer survey, about 60% of people want "lightening of discharge gun".

Equipped with an LED light that illuminates the application location. Light and soft! High voltage cable and Ground return cable.

One-touch exchangeable CR unit. Easily exchangeable gun head.
