Fluke 1773 records voltage, current, power and energy in three-phase systems and helps investigate power quality problems. PQ Meter displays live measurements, while PQ Logging supports extended surveys. Connection error detection and channel correction simplify setup. The 1773 supports load and energy surveys, harmonic studies and basic power quality investigations; it does not include high-speed voltage transient capture. The standard package contains four flexible 1500 A iFlex probes. BASIC versions exclude current probes. Energy Analyze Plus software supports recorded-data analysis and reporting.
