8.3.8 WAVEFORM CAPTURE
The 469PC software can be used to capture waveforms from the 469 at the instant of a trip. A maximum of 64
cycles can be captured and the trigger point can be adjusted to anywhere within the set cycles. A maximum of
16 waveforms can be buffered (stored) with the buffer/cycle trade-off.
The waveforms captured are:
• Phase Currents A, B, and C
• Differential Currents A, B, and C
• Ground Current
• Phase Voltages A-N, B-N, and C-N
