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.

Thanks to stabilized HV output the NSG 437 ESD simulator comprehensively fulfills 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 fulfills the high demand for different test applications and

can be exchanged. Completed by a wide selection of rigid and flexible 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 every start-up. This procedure

runs up to max. voltage in either polarity, thus giving confidence, that test levels are maintained within

tolerances.
