Find Little Problems Before They Become Big Ones
TrendCapture is a powerful feature which quickly graphically displays logged data sessions to quickly determine whether anomalies may have occurred. The 289 also includes a selectable AC filter (smoothing mode) to help display a steadier reading when the input signal is changing rapidly or noisy. Adjustable recording and auto-hold thresholds allow you to specify a percentage change in the readings that begins a new event.
The Fluke 289 also comes with an integrated low pass filter for accurate voltage and frequency measurements at the same time on adjustable speed motor drives and other electrically noisy equipment. Also included is Fluke's LoZ Volts feature, a low impedance voltage function for eliminating ghost voltages. This is recommended when testing for the absence or presence of live power. These features make the 289 a powerful tool for use in a wide range of demanding industrial applications.
