However, please note that Noise Laboratory Co., Ltd. and its sales agents accept no liability for compensation for any losses or similar, or damage to the EUT (Equipment Under Test) or other peripheral equipment, caused by faults in the instrument, deterioration of consumables, or other external causes. 13 7. POINTS TO NOTE REGARDING CONSUMABLE ITEMS Secondary Battery for Memory Backup The instrument contains a secondary battery used to maintain memory data while the power is turned off. The secondary battery is a consumable item. The secondary battery deteriorates with repeated charging and discharging and the charging capacity steadily falls with normal use. If the memory backup fails to function even when the battery is charged, the cause may be deterioration of the secondary battery. In this case, please contact your sales agent or the Noise Laboratory repair and calibration center to arrange replacement. Do not attempt to repair the instrument yourself as this is very dangerous. The secondary battery may go flat resulting in loss of memory data if the instrument remains unused for two months or more. If the memory backup fails to function, the stored settings and display settings when the power is turned on revert to their defaults. If you want to maintain a memory backup over a long period, please leave the power to the instrument turned on for approximately 24 hours once every two months. (The actual recharging time may vary depending on the operation conditions and environment.) * Please note that Noise Laboratory Co. Ltd. accepts no liability for loss of backup data due to battery wear, fault, misoperation, or other reason. Please make a note of important settings information beforehand. High-Voltage Relay The main unit and discharge gun contain high-voltage relays. The high-voltage relays are consumable items. The electrical contacts in the high-voltage relays deteriorate with use and this can result in poor electrical connections, 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, the cause may be deterioration of a high-voltage relay. In this case, please contact your sales agent or the Noise Laboratory repair and calibration center. Do not attempt to repair the instrument yourself as this is very dangerous. 14 7. POINTS TO NOTE REGARDING CONSUMABLE ITEMS Fuse This instrument contains fuses. A fuse holder is located in the AC inlet on the rear panel and the fuse can be replaced by the user.

RADIATION LEVEL MODE FUNCTION To improve the reliability of its electrostatic discharge simulators, Noise Laboratory released the new TC-815R discharge gun in 2004. The new discharge gun was an upgrade of the TC-815P model and featured reduced ringing in the output current waveform and lower radiated noise from the discharge gun. Whereas there is a trend towards lower operating voltages and faster CPU clock speeds in modern electronic components and equipment, and also a switch to plastic cases that are increasingly being adopted as devices become smaller, this has also been accompanied by a deterioration in immunity to noise, including poorer shielding performance and greater sensitivity to radiated noise. A consequence of this is that there have been reports of EUTs malfunctioning due to radiated noise from the discharge gun. There is a limit to how much radiated noise can be reduced by improvements to the discharge gun and accordingly a new function called the "Radiation Level Mode Selection Function" has been developed and incorporated into the electrostatic discharge simulator to reduce radiated noise. The new Radiation Level Mode Selection Function effectively combines two types of electrostatic discharge simulator in the same unit, being able to select between its default setting of normal mode (NORMAL), which provides the same conditions as electrostatic discharge simulators that comply with the IEC 61000-4-2 and ISO 10605 standards (referred to below as "previous simulators"), and extra mode (EXTRA), which produces a lower level of radiation. 9-1. Points to Note When Using the Radiation Level Mode Function Regardless of the radiation level mode, the simulator performs electrostatic discharge immunity tests that comply with the IEC 61000-4-2 and ISO 10605 standards. However, because the level of radiated noise from the discharge gun in extra mode (EXTRA) is lower than in the normal mode (NORMAL) used by previous simulators, results may differ from past tests. When using extra mode (EXTRA), please verify consistency with past test results. Also, if performing tests using both radiation level modes, please record whether you used normal mode (NORMAL) or extra mode (EXTRA) in the test report or similar to ensure that you have sufficient information to reproduce the test. 9-2. Differences Between Normal Mode (NORMAL) and Extra Mode (EXTRA) Although the simulator performs electrostatic discharge immunity tests that comply with the IEC 61000-4-2 and ISO 10605 standards regardless of the radiation level mode, there are differences between normal mode (NORMAL) and extra mode (EXTRA). [1] Different level of radiated noise The radiated noise in normal mode (NORMAL) is at a similar level to previous simulators. The radiated noise in extra mode (EXTRA) is lower. 21 9. RADIATION LEVEL MODE FUNCTION [2] Different voltage waveform With IEC 61000-4-2 and ISO 10605 standards, there is the difference in the voltage waveform which does not have stipulation. Conditions under which differences in waveform appear. Electrostatic discharge mode: Contact discharge The electrostatic discharge is applied to a point at which the impedance between the discharge tip and discharge gun GND is 2MΩ or more. The figures below show the voltage waveforms when a 1000:1 high-voltage probe is connected to an oscilloscope, and where the impedance between the discharge tip and discharge gun GND is approximately 100MΩ. ESS setting: +2kV, contact discharge, TC-815R discharge gun Figure 9-1 Normal Mode Voltage Waveform 9-3. Figure 9-2 Extra Mode Voltage Waveform How to Use the Radiation Level Modes The radiation level modes are normal mode (NORMAL) [Switch LED turns on] and extra mode (EXTRA) [Switch LED turns off]. The simulator always starts up with the radiation level mode set to normal mode (NORMAL) when the POWER switch is turned on. Also, the radiation level mode selection cannot be changed while the simulator is running. The LED in the radiation level mode selection switch turns off to indicate that the simulator is in normal mode (NORMAL). Normal mode (NORMAL) can be used to perform testing in the same way as previous simulators. Note: The above does not guarantee that test results will be identical to those obtained from previous simulators. Individual variability of the simulator and discharge gun will cause differences in the results. 22 9. RADIATION LEVEL MODE FUNCTION 9-4. How to Select Extra Mode (EXTRA) If the radiation level mode selection switch is held down when the POWER switch is turned on, the simulator starts up in extra mode (EXTRA). (When the POWER switch is turned on normally, the simulator starts in normal mode (NORMAL).) The radiation level mode selection cannot be changed while the simulator is running. The LED in the radiation level mode selection switch turns on to indicate that the simulator is in extra mode (EXTRA). Selecting extra mode (EXTRA) reduces the radiation from the discharge gun. The minimum repeat cycle in extra mode (EXTRA) is restricted to 1.0s. LED in Radiation Level Mode Minimum Repeat Selection Switch Cycle Normal mode (NORMAL) Off 0.05s min Extra mode (EXTRA) On 1.00s min Radiation Level Mode Figure 9-3 Lower Section of Operation Panel (Front Panel) How to select extra mode (EXTRA) Holding down the EXTRA/NORMAL switch on the simulator when turning on the POWER switch starts the simulator in extra mode (EXTRA). On Off How to select normal mode (NORMAL) Turning on the POWER switch normally starts the simulator in normal mode (NORMAL). Figure 9-4 Power Switch (Rear Panel) 23 10. 10-1.

Connecting the AC Power Cable Plug the AC power cable into a socket that has a protective earth terminal The AC power cable provided with the instrument has a three-pin plug that connects to the power supply and protective earth terminal. The protective earth on the three-pin plug connects via the AC power cable to the metal parts on the instrument. Because this provides protection from electric shock, ensure that you plug the power supply cable into a socket that has a properly earthed protective earth terminal. Using the instrument without a protective earth connection may result in electric shock. Firmly insert the AC power cable plug into the socket Failing to fully insert the plug may result in heating or the build-up of dust leading to fire, electric shock, or similar. Failing to fully insert the plug or plugging too many cables into the same power outlet may cause cables to overheat leading to fire, electric shock, or similar. Do not use the AC power cable for any other purpose The supplied AC power cable is only intended for use with this instrument. Do not use it for any purpose other than this instrument. Use on any other electrical equipment risks overheating leading to fire, electric shock, or similar. Similarly, using an AC power cable from another electrical device may prevent the instrument from operating at its intended level of performance and may result in overheating if the current carrying capacity of the cable is insufficient, leading to fire, electric shock, or similar. Clean the AC plug periodically Allowing dust or dirt to accumulate between the AC plug and socket and absorb moisture may reduce the electrical insulation and result in fire. Periodically unplug the AC plug from the mains socket and clean off any dirt or dust using a dry cloth. Do not operate the instrument or insert or remove the AC plug if you have wet hands Failure to comply with this rule may result in electric shock or faults. An AC power cable with a three-pin plug is provided with the simulator to connect to the mains power supply and protective earth. The protective earth on the three-pin plug connects via the AC power cable to the metal parts on the simulator. Because this provides protection from electric shock, ensure that you plug the power supply cable into a socket that has a properly earthed protective earth terminal. Using the instrument without a protective earth connection may result in electric shock. AC inlet Figure 10-2 AC Inlet on Rear of Unit 25 11. 11-1.

Starting and Stopping a Test 11-3-1. Starting a Test Warning ・ Before you start, check that the discharge gun is connected. ・ Starting a test will generate the indicated voltage. Take adequate precautions. ・ Take care to ensure there are no other people close to the discharge gun or simulator, and that all necessary preparation for the discharge test has been carried out. After specifying the settings, press the START switch to start the test. The warning lamp illuminates to indicate that a voltage is being output from the high-voltage output connector to charge the charging capacitor in the discharge gun. The warning lamp starts to blink when you press the trigger switch to perform an electrostatic discharge. 11-3-2. Stopping a Test Warning ・ As the simulator waits for the next trigger input after the specified number of discharges have been performed, the high-voltage power supply in the simulator does not turn off. Always press the STOP switch to end the test. Press the STOP switch (red). This stops the test, turns off the voltage output, and extinguishes the warning lamp. Figure 11-9 Operation Panel START and STOP Controls 34 12. BACKGROUND KNOWLEDGE ABOUT ELECTROSTATIC TESTING 1) Principle of electrostatic tester The basic circuit of an electrostatic is shown below. The high voltage generated in the high voltage power supply is charged in the charging capacitor through the charging relay and charging resistance. When the charging relay is turned off and the discharging relay is turned on, the high voltage (electric charge) accumulated in the charging capacitor is applied to EUT through the discharging resistance. RL1 : Charging relay RL2 : Discharging relay R1 : Charging resistor R2 : Discharging resistor C : Charge/discharge capacitor A : High-voltage power supply B : Discharge tip Figure 12-1 Basic Circuit for an Electrostatic Discharge Simulator (From IEC 61000-4-2 Standard) 2) Electrostatic test by IEC standards The international Electrotechnical Commission (IEC) issued the Standards for Electrostatic Discharge Requirements Pub. 61000-4-2, which defined tester circuits and constants, discharge current waveforms, test voltage levels, test environments, etc. A combination of the ESS-2000 and discharge gun can be used for electrostatic discharge tests conforming to IEC pub. 61000-4-2. 35 12. Background Knowledge About Electrostatic Testing 3) Contact Discharge and Air Discharge The electrostatic discharge can be applied either by direct contact (CONTACT) or via the air (AIR). The test procedure and electrostatic simulator operation are different in each case, as described below. The effect on the EUT is also different. - Contact discharge (CONTACT) The electrostatic discharge is applied by placing the discharge tip in direct contact with the case of the EUT (if the case is painted, the paint is peeled off to allow contact). Coupling between the internal circuits and the discharge current that flows through the case of the EUT causes the EUT to malfunction. Because the discharge contacts the EUT directly, this method of testing has a comparatively good level of repeatability. The test uses a cone-shaped discharge tip that extends out from the end of the discharge gun. After bringing the discharge gun into contact with the measurement point on the EUT, the trigger is input to apply the specified number of discharges to the EUT at the specified time intervals. The charging relay and discharge relay turn on and off in tandem to alternately charge the charge/discharge capacitor and then discharge it into the EUT. Discharging can be paused by inputting another trigger while discharge is in progress. - Air discharge (AIR) In the IEC standard, this method is used in situations when contact discharge is not practical (when it is stipulated that an insulating coating is applied or the EUT case is made of an insulator). In this method, the discharge gun uses a discharge tip with circular shape. Turn on the trigger with the discharge gun held away from the EUT and then as rapidly as possible bring the discharge tip closer until it comes into contact with the EUT. After the discharge occurs, pull the discharge tip (discharge gun) back away from the EUT and turn off the trigger. To perform another discharge, turn the trigger on again and repeat the above procedure. The simulator allows air discharge or contact discharge to be selected for each test item. As described above, the difference between the two modes is in the different operation of the charging and discharging relays and the use of the trigger switch. Also, the discharge interval setting is not applicable when using air discharge mode. 4) Test Procedure for Electrostatic Testing Electrostatic testing must be performed under specific conditions including factors such as the ground plane and coupling plane. Refer to the "IEC61000-4-2" standard published by the IEC for details. 36 13. ERROR DISPLAY Err 1 Description of error The discharge gun is not connected. Interlock error Press the STOP switch. How to clear error How to prevent error Insert the high-voltage input connector of the discharge gun into the high-voltage output connector on the main unit of the simulator. Rotate the securing ring on the high-voltage input connector of the discharge gun clockwise to secure in place. (See "10. CONNECTIONS") Err 2 The secondary battery used for memory backup is flat. Description of error Press the STOP switch. How to clear error How to prevent error Turn on the power to the simulator for approximate 24 hours to allow the battery to recharge. If Err 2 continues to appear even after recharging, the cause may be deterioration of the secondary battery.
