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 fullls 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 106 05 ensure that the simulator is automatically
set up correctly and the appropriate discharge net work 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 congurations 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
specic 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 carr ying case with space for accessories.
