Electrical load studies, energy consumption testing, and general power quality logging

The Fluke 1735 Power Logger is the ideal electrician or technician's power meter for conducting energy studies and basic power quality logging. Set the Power Logger up in seconds with the included flexible current probes and color display. The power quality meter measures most electrical power parameters, harmonics, and captures voltage events.

Key Features

Record power and associated parameters for up to 45 days
Monitor maximum power demand over user-defined averaging periods
Prove the benefit of efficiency improvements with energy consumption tests
Measure harmonic distortion caused by electronic loads
Improve reliability by capturing voltage dips and swells from load switching
Easily confirm instrument setup with color display of waveforms and trends
Measure all three phases and neutral with included 4 flexible current probes
View graphs and generate reports with included Power Log software
Compact, rugged design with IP65 case, 600 V CAT III and two-year warranty

Applications

Load studies - verify electrical system capacity before adding loads
Energy assessments - quantify energy consumption before and after improvements to justify energy saving devices
Harmonics measurements - uncover harmonic issues that can damage or disrupt critical equipment
Voltage event capture - monitor for dips and swells that cause spurious resets or nuisance circuit breaker tripping

Log the most common parameters

Designed to measure the most critical three-phase power parameters, the 1735 can log rms voltage, rms current, phase angle, voltage events, voltage and current THD, voltage and current harmonics up to the 50th, active power, reactive power, power factor, active energy, reactive energy, and more. With memory for up to 45 days of data, the 1735 can uncover intermittent or hard-to-find issues.

Easy to use

The four current probes are connected with one plug, the instrument automatically detects, scales and powers the probes. These variable range current probes are easily set to 15 A, 150 A, or 3000 A for high accuracy in nearly any application. The voltage connections are single leads, enabling easy and quick setups. The color screen provides instant confirmation that connections are correct, and then logging begins when you press the RECORD button.

Generate reports and view graphs with Fluke Power Log Software

Designed to quickly view recorded data, the included Power Log software displays all recorded parameters on interactive trends. Generate a professional report with the 'Report Writer' function, or copy and paste images into report document manually.

Conduct load studies for up to 45 days and view saved data on-screen or on a computer.

Quantify energy consumption quickly on-screen or log to memory for extended periods.
