1750 Power Recorder 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 or the Product,” 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 (not included in Basic version).
1750 Operators Manual • Automatic disturbance capture The Recorder uses an automatic, self-learning threshold routine, which means you do not have to set any event threshold limits before you start recording. You detect and display power quality events (disturbances) using the Power Analyze software on a PC after the event has been captured. You define thresholds for events after data is stored on the PC. This is called the "event detector" in the software.
Power Recorder Safety Information Safety Information See the Specifications section for a full agency compliance list. Table 1 lists symbols that appear on the Recorder and in this manual. XW Warning To prevent possible electrical shock, fire, or personal injury: • Carefully read all instructions. • Do not work alone. • Do not use the Product around explosive gas, vapor, or in damp or wet environments. • Use only insulated current probes, test leads, and adapters as supplied with the Product.
