Power Analyzer Upgrades
For PS4550/PS4500 Only
The unique PowerSight® High Frequency Analysis Option (FAO) extends the capability of your meter by adding power-line spectrum analysis capabilities. View power-line noise spectra from 3KHz to 100KHz on both voltage and current to verify the effectiveness of power-line filtering beyond the normal harmonic range.
Only for PS4550/PS3550/PS4500
The Expanded Memory Option is recommended for the PS4550 to provide plenty of space for extensive data logging and power quality data capture. It expands the internal memory four times (X4). Standard memory is adequate for limited power logging and power quality data capture.
