The Fluke 289 True-RMS Logging MultiMate with Trend Capture is the ultimate handheld tool for demanding applications that require high-precision. It quickly documents design performance and graphically displays what happened. Saving measurements allows you to name and recall measurements made in the field, and it has a real time clock for automatic time stamping of saved readings. Its-Feet unique logging and graphing capabilities mean you no longer need to download logged readings to a PC to detect a trend, and it stores up to 15,000 recorded events. The low impedance voltage function prevents false readings due to ghost voltage. The true-RMS AC voltage and current accurately measures complex signals or non-linear loads. The selectable AC filter helps display a steadier reading when the input signal is changing rapidly or is noisy. The adjustable recording and auto hold thresholds specify a percentage change in the readings that begins a new event. The 289 features a large 50,000 count, 1/4 VGA display with a white backlight, that allows multiple sets of measurement information to be simultaneously displayed at the same time. The millimeter runs about 100 hours, 200 hours in logging mode, on 6 AA alkaline batteries, or NEDA 15A IEC LR6.
