1750 Power Recorder Operators Manual Introduction The Fluke 1750 Power Recorder is a comprehensive yet easy to use system for power quality investigations. The 1750 Power Recorder, referred to hereafter as simply “the Recorder”, consists of a power recorder instrument, a wireless handheld Personal Digital Assistant (PDA) for control and setup, and a powerful yet easy to use PC application, Power Analyze. Four 400 A current probes are provided as standard equipment.
1750 Operators Manual With these features, there is little else required to set up and start recording the data to conduct a power quality survey. Should you want to extensively analyze collected data, the procedures described later in this manual review the transfer of data from the Recorder to the PDA, and finally to a PC. Data may then be analyzed using Power Analyze on a PC. Extensive online help is provided in the Power Analyze software on the product CD shipped with the Recorder.
