Page 5: Introduction
Introduction The ESD simulator SESD 216 / SESD 230 is suitable for performing EMC tests on systems and equipment in accordance with the IEC / EN 61000-4 Part 2 standard. This test is concerned with the immunity behavior to electrostatic discharge. Depending on the DUT and test setup, two test procedures are to be used: a) Air Discharge The discharge electrode with the domed point should first be connected to the SESD. -
Page 6: Safety Instructions
The use of the ESD generator assumes, like all measurement tasks and verifications, that the local and branch specific directions are considered. Precautions should be taken that any part that carries high voltage and can be touched should be shielded. This is important with both the ESD Generator and the object under test. Warning / Danger While using the ESD generators it must be made sure that the ground / earth connection is fastened at the generators ground and connected to earth potential. -
Page 7: Impairment Of Safety
ESD generator. Damage to the power supply due to lack of protective earth is not covered by the warranty. The ESD generators SESD 216 and SESD 230 are according to its specifications designed only for laboratory use in the industrial surrounding (tests in a Faraday’s cage). -

5.4.2 Special function – displaying of the real discharge voltage at AIR mode In the test mode “AIR” and “Single” the “real discharge voltage” can be shown in the display. After the discharge and hold-on the trigger button [9] the voltage in the display changes from the adjusted voltage to the real discharge voltage. -

5.8 LCD - Display The upper line of the display shows the test voltage in kV and polarity. The second line is empty. In the counter mode – see chapter 5.6 – the display shows the quantity of discharged pulses. The left side of the third line gives information about the test mode (CON / AIR), the right side shows the selected repetition frequency. -
Page 16: Power Supply
5.12 Power supply The generator is connected to the power supply via the socket [13]. The ESD generator can be used either independently, using the built in batteries or while connected to the mains supply. After the charging of the accumulator (the charge line is than showing full on the display), the power supply can be removed and the testing can go on with the accumulator only. -

(STA), final voltage (END) and step size (STE). In the example shown, there are a total of 46 steps, with five ESD discharges per step. The total test time depends on the selected repetition frequency. -
Page 20: Programming The Automatic Tests
7.3 Programming the automatic tests After activating the setup function - chapter 7.1 - select a memory location that you want to program. In principle, existing memory locations SET 01 - SET 20 can be overwritten or, if not yet occupied, rewritten. All 20 memory locations are numbered, these numbers - SET 01 to SET 20 - cannot be changed. -

Page 27: Maintenance / Calibration
14 Maintenance / calibration The instrument is largely maintenance-free. We recommend having the instrument calibrated at our premises every two years, e.g. for ISO 9001 certifi- cation. 15 Packing / transport If you return the device to the manufacturer for calibration or repair, use the foam inserts for shipping that you received with the delivery.
