Fluke 1736 Three-Phase Power Logger

Fits portable three-phase energy studies and basic power quality logging where you need V/A/Hz, power, PF, energy, demand, harmonics to the 50th, and event capture with waveform snapshot — powered from the measured circuit.

Key advantages

Three-phase + neutral logging — Four flexible current probes included; V/A/Hz/power/PF/energy/demand.
Harmonics to 50th + events — Dips, swells, inrush with waveform snapshot and high-res RMS profile.
1000 V CAT III / 600 V CAT IV — Power from the measured circuit; Energy Analyze Plus included.
2 DC aux channels — External temperature/humidity/air-speed sensors; Wi-Fi / Fluke Connect / VNC setup.

Typical applications

Portable energy studies and basic power quality logging on three-phase systems.
Load studies needing included flexible probes and long memory (>1 year typical).
Surveys that add DC aux environmental sensors alongside electrical logging.

Selection guide

Measurements — V, A, Hz, power (W/VA/var), PF, energy, demand, harmonics to 50th, THD, events.
Phases — Three-phase + neutral with included 4 flexible current probes.
Safety — 1000 V CAT III / 600 V CAT IV.
Logging — Automatic logging of 500+ PQ parameters; >20 sessions; >1 year memory typical.
Events — Dips, swells, inrush with waveform snapshot and high-res RMS profile.
Display — Colour touch screen for in-field analysis.
Connectivity — USB; Wi-Fi; Fluke Connect mobile/desktop; VNC setup.
Powering — Power instrument directly from the measured circuit.
Software — Fluke Energy Analyze Plus included.
DC aux — 2 DC channels for external sensors (temperature/humidity/air speed).
Special features — Intelligent connection verification; guided graphical setup.
Functions — Energy studies, load studies, basic power quality logging.
Form — Portable three-phase power quality logger.

Common mistakes

Ordering 1736 when the job requires 1738-only Fluke Connect co-logging of two extra FC parameters — confirm feature need first.
Ignoring CAT III 1000 V / CAT IV 600 V limits at the measurement point.
Leaving DC aux sensor plan blank when temperature/humidity/air speed correlation is part of the study.
Assuming unlimited memory without planning session count (>20 sessions; >1 year memory typical).
Skipping connection verification / guided setup when multi-phase wiring errors are common on first install.

When to RFQ / what to tell us

Study type (energy, load, basic PQ) and system voltage/current ranges.
Need for DC aux sensors and Fluke Connect / Wi-Fi workflow.
Quantity, ship-to, and whether 1738 co-log features are required instead.
