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

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 Fluke 1735 can log rms voltage, rms current, phase angle, voltage events, voltage and cur-rent 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 Fluke 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.
