Atec NSG437 User Manual
nsg 437 esd
high performance with basic features
The NSG 437 simulator is designed to sit comfortably in the operator’s hand, with current operating
conditions constantly displayed and clearly visible. The simulator is ergonomically designed to be held
easily for long duration test procedures.
The touch panel display with its keypad for parameter settings shows the precise functional and test data
at any moment. All essential functions and actual status are displayed, with user-selectable language
for convenient and safe operation worldwide.
Pre-programmed settings for IEC/EN 61000-4-2 and ISO 10605 ensure that the simulator is automatically
set up correctly. The menu with last settings automatically comes up again after shut-down of a test
sequence.
Air- and contact-discharge
up to 30 kV
Light version featuring un-
compromised test performance
Compliant with a wide range of
standards (IEC, ANSI, SAE, ISO)
Touch panel display controls
Easily and quickly interchange-
able network modules
Wide range of accessories
(HV networks, tips, adapters)
Thanks to stabilized HV output the NSG 437 ESD simulator comprehensively fullls virtually all international standard requirements. Based on over 20 optional discharge networks, the NSG 437 can also meet
any of today’s automotive manufacturers’ standards.
NSG 437 generates pulses from 200 V to 30 kV, both in air- and contact-discharge operation. The simulator is simple, convenient and safe to use. The whole range of parameter setting possibilities, including
polarity selection, counter functions and breakdown detection, remains fully available up to the maximum
discharge voltage.
The simulator contains a threshold detector to eliminate faulty discharge counts over its wide operating
voltage range. Only valid HV discharges are indicated. When discharges are detected, the counter or
preset counter is incremented or decremented respectively – a particularly useful feature for long test
runs. The detection feature can be switched off when testing EUT’s with non-conductive surfaces, such
as plastic housings.
A wide range of discharge networks and tips fullls the high demand for different test applications and
can be exchanged. Completed by a wide selection of rigid and exible discharge tips, any application
is possible. Molded HV discharge networks in solid cases eliminate internally ionization and leakage
current effects. Selected combinations of RC components guarantee wave shape parameters to be
within tolerances. Discharge network modules with resistance values from zero ohms combined with
capacitances up to the nF-range can be simply pushed into place.
Automatic self-calibration of the NSG 437 simulator is performed at ever y start-up. This procedure
runs up to max. voltage in either polarity, thus giving condence, that test levels are maintained within
tolerances.
