Introduction
The Fluke 434 Analyzer can capture waveforms at high-resolution during a variety of
disturbances. The Analyzer will give a snapshot of the voltage and current waveforms at
the precise time of the disturbance. This allows you to see the waveforms during dips,
swells, interruptions, current swells and transients.
Transients are fast spikes on the voltage (or current) waveform. Transients can have so
much energy that sensitive electronic equipment can be affected or even damaged. The
Transients screen looks similar to that of Scope Waveform, but its vertical span is
enlarged to make voltage spikes visible that are superimposed on the 60 or 50 Hz
sinewave. A waveform is captured each time that the voltage (or rms current) exceeds
adjustable limits. A maximum of 40 events can be captured. The sample rate is 200 kS/s.
