Product Overview

Air- and contact-discharge up to 30 kV Compliant with a wide range of standards (IEC, ANSI, SAE, ISO) Built-in ISO self-calibration procedure Powered by high-energy battery pack Touch panel display controls Easily and quickly interchangeable network modules Adjustable discharge detector This kit contains the "basic set" of accessories as follows - Carrying case with: discharge pistol, cradle for discharge pistol, high voltage base unit with built-in battery pack, mains adapter and battery charging unit (100 to 250 VAC), air- and contact-discharge tips, 150 pF/330 Ohm discharge network, grounding cable, user manual, 25 mm discharge sphere.  Additional items supplied in this kit which are not part of the basic set are the INA 4415 Flexible tip set, and INA 4420 H-Field adapter, and the optional ISO 10605 networks 150 pf/2 KOhm, and 330 pF/2 KOhm.  Ergonomic design and advanced functionality. The pistol-shaped NSG 438 simulator is designed to sit comfortably in the operator¿s hand, with current operating conditions constantly displayed and clearly visible. NSG 438 ESD simulator comprehensively fulfi lls virtually all international standard requirements and supports proposed future standards. Based on over 20 optional discharge networks, the NSG 438 can also meet any of today¿s automotive manufacturers¿ standards. The simulator is simple, convenient and safe to use. The whole range of parameter setting possibilities, including polarity selection, freely adjustable pulse repetition, counter functions and breakdown detection, remains fully available up to the maximum discharge voltage. The touch panel display with its virtual thumb wheel or keypad for parameter settings shows the precise functional and test data with user-selectable language for convenient and safe operation worldwide. The simulator contains variable threshold selection to enable accurate discharge detection. This detection feature can be switched off when testing EUT¿s with non-conductive surfaces, such as plastic housings. Pre-programmed settings for IEC/EN 61000-4-2 and ISO 10605 ensure that the simulator is automatically set up correctly and the appropriate discharge network is installed. The actual RC value is displayed at all times. Molded HV discharge networks in solid cases eliminate ionization and leakage current effects. Selected combinations of RC components guarantee wave shape parameters to be within tolerances. An integral interlock system allows setting up accessibility and safety confi gurations even in combination with other test instruments. For extra safety and emergency an emergency stop switch is built in. With the built-in ISO calibration self-test feature considerable time can be saved by eliminating extra calibration and functional measurements before starting a test procedure as required by the ISO standard. More specifi c features are freely adjustable pulse repetition rate for R&D purpose, a special random generator function to cut down test times and an optional charge remover for discharging the EUT. NSG 438 is packed in a convenient and stable carrying case with space for accessories.
