Fluke 1750 Three Phase Power Quality Recorder

 Fluke 1750 Three-Phase Power Recorder
Capture every measurement, every event, on every cycle, all the time with the Fluke 1750 Power Recorder. Outstanding accuracy and resolution provide complete visibility into your installation or distribution system.

Easy to use
The recorder automatically detects, scales, and powers current probes without needing batteries. Requiring only single-lead voltage connections enables safe and quick setups. Once power is applied the instrument automatically begins recording and LEDs give you assurance that the recorder is powered up and signals are within range ﾖ no more uncertainty that data is being recorded. The Fluke 1750 has an exclusive capture algorithm which makes certain all events are captured without the tedious setups and blind spots associated with threshold driven equipment. The PDA wirelessly interfaces with the recorder, allowing quick setup and verification with waveform displays, meter screens, and phasor diagrams. The built-in wireless technology allows you to control multiple instruments from a distance easily, without the need for a laptop computer (laptops can also be used when desired).

Comprehensive power system data
Every cycle on every channel is simultaneously sampled providing complete analysis of power quality, harmonics, power and energy. Cross channel current and voltage triggering captures event data on all input channels simultaneously, no matter which channel triggered the event. When periodic analysis of the waveform may be needed, the Snapshot mode captures waveforms at user defined intervals. Even dc signals can be recorded!

Powerful data management
Data is automatically stored on the internal flash memory that can store records for over a month without compression or overwriting. Data is retrieved via one of two quick and easy options: download the data onto the SD memory card without using your laptop, or transfer directly to your computer via Ethernet, using TCP/IP protocol.Voice, data, and picture annotations can be made via the PDA to fl ag important points in the data stream. Imagine being able to fl ag in your recorded data when a transfer switch was operated, or load changes were made.

View data the way you want
The new Fluke Power Analyze software revolutionizes your ability to analyze data. No need to worry about thresholdsﾗwith Fluke Power Analyze, thresholds can be modifi ed after the data is recorded! And the easy-to-use user interface will display voltage as a phase-to-phase or phase-to-neutral reading.

All the latest power quality standards are built-in
IEC 61000-4-30 compliant measurement systems provide the confidence that all parameters are measured and calculated consistently with international standards. Automated EN50160 compliance reporting for rapid Pass/Fail testing.

600 V CAT IV and 1000 V CAT III safety rating
Designed to help protect you and your equipment, the Fluke 1750 Three-Phase Power Recorder and accessories are all certified to meet the stringent safety standards for use in 600 V CAT IV and 1000 V CAT III environments. They are the first tools of their kind to carry the CAT IV rating and, therefore, can be used for most power connections and for all outlets in a low-voltage power distribution system.
