    The NSG 439 simulator is not a toy! It is a professional tool and belongs only in the hands of specialists and appropriately trained personnel. When powered by its own batteries the simulator can be active even without any power cable being connected.
  • Page 7 The instrument’s housing and the cable have both an insulating and a screen- ing function, which can only be assured while the housing is intact. Return a damaged simulator to a Teseq service centre immediately for repair. Teseq AG Luterbach, Switzerland and the associated sales organization accept no responsibility for personal or material damage nor for any consequential damage that results from irresponsible operation of this instrument.

    (EMC) is, today, a necessity if one is not prepared to suffer the economic disadvantages that could otherwise ensue. As a logical consequence, appropriate testing is now a legal requirement for the sale of electronic products within the EU. NSG 439/439A ESD simulator for robotic solution...
  • Page 9 The ESD test plays an important role in the range of interference sensitivity tests. It simulates frequently occurring effects and guides the development engineer to any weak spots in an instrument or item of equipment through a combination of high voltage and high frequency properties. A simulation device must be constructed such that it reproduces practical con- ditions realistically.

    The charge voltage to the network is kept constant as long as the trigger is active. The high voltage is discharged internally when the trigger is reset. If no discharge occurs when set for an air-discharge and the trigger is active, the processor waits for about 30 s then autonomously resets the trigger and discharges the network internally with simultaneous acoustic warning.

    4.2.1. Battery charger/power supply unit Power to the instrument is provided through a universal mains unit suitable for input voltages between 80 and 240 VAC. This same unit also serves as a charger for the integral battery pack. Charging of the battery takes about three hours. At this point a timer switches the charger to a reduced charging current and the indicator lamp changes from red to green.
