The Fluke 1750-TF Power Recorder is a comprehensive yet easy to use system for power quality investigations. The 1750-TF Power 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 iFlex current probes are provided as standard equipment. A wide range of flexible and clamp-on current probes are available from Fluke. Key features of the 1750 Power Recorder are: No PC needed for setup Using the included a wireless-enabled Personal Digital Assistant (PDA) as a controller, you do not need a PC to configure the Recorder, troubleshoot connections, preview data, or download the recorded data. Downloaded data goes onto the SD memory card plugged into the 1750, not directly to the PDA. The range of the PDA with the wireless link is about 15 meters (45 feet) from the 1750-TF. Simplified test lead connections to the power network Simply connect a voltage probe to a conductor on each phase that you want to record. On the current inputs, the 1750 TF automatically identifies what type of probe is connected. It then configures its measurement system appropriately for the model of current probe you are using. Connection diagrams for the supported power network configurations (delta, Wye, and others) appear on the handheld PDA controller. Once you make connections, you can view live readings and a phasor diagram on the PDA to confirm the connections. If a phase channel is wired incorrectly, you can swap the phase to another channel by changing an internal Recorder setting using the PDA, and then reconfirm correct readings. Internal Uninterruptible Power Supply (UPS) An internal NiMH (Nickel-Metal-Hydride) battery pack and charging system maintain data capture continuity through power interruptions of 5 minutes or less. 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.
