Refurbished Dynatech Nevada Impulse 3000 Defibrillator Analyzer
Impulse 3000 is a precision instrument that makes the measurements required to thoroughly test the performance of defibrillators. The main function of the Impulse 3000 is to measure the energy output of a defibrillator.
- The impulse 3000 has two energy ranges. The low range is designed to be especially useful to test low-power defibs, including
- An internally generated pulse, similar to an actual defib pulse, can be used to test the equipment under test (EUT) or to simulate
a pulse when desired.
- The paddle contact plates are connected to the ECG signal so the defib can pick up the heartbeat waveform through its paddles.
The paddle contact plates have a provision (a hole in the mounting screw) for plugging in special contacts for internal defib
paddles. These contacts are included as standard accessories. In addition, special contacts for connecting to specific defibs are
available as optional accessories.
- The Impulse 3000 can be powered from a battery for portable operation, or from the line with the Battery Eliminator.
- The Impulse 3000 uses a true differential amplifier input so that the defib can be fired from either polarity. The energy is
measured correctly even from grounded defibs. For proper polarity of the scope output, put the apex (+) paddle on the right and
the sternum (-) paddle on the left.
- The Impulse 3000, under control of a microprocessor, measures and stores the instantaneous voltage of the defib pulse every 125 microseconds, 512 times, fiving a measurement window of 64 milliseconds.
- The instrument has a serial RS-232 port that can be used to output test results to a printer, the medTester (software version 3.16 and above), or other devices.
- The medTester interfaces with the Impulse 3000 via a specialized cable available from DNI Nevada and the RS-232 of both units.
