True-RMS Multimeter Performs Industrial Logging

Oct 17, 2007 5:23 PM

The Fluke 289 from Fluke Corporation is a True-rms industrial logging multimeter that includes a TrendCapture feature. The meter features a logging function with expanded memory that stores up to 10,000 readings for unattended monitoring of signals over time. Users can save multiple logging sessions before PC download is necessary and review logged readings in graphical format directly on the meter display using on-board TrendCapture capability. The meter also features a 50,000-count, 3.5-in. 1/4 VGA dot-matrix display with a white backlight that can simultaneously display multiple sets of measurement information.

The Fluke 289 has a two-terminal 50-Ω range with 1-m Ω resolution and 10 mA source current. It also features a low-pass filter for accurate voltage and frequency measurements on adjustable-speed motor drives and other electrically noisy equipment, as well as a “LoZ Volts” low-impedance voltage function for eliminating ghost voltages or for use when testing for the presence of live power. It has a 50 mF capacitance range, peak capture to record transients as fast as 250 μs, is capable of measuring up to 10 A (or 20 A for 30 seconds), and has a relative mode that removes test-lead resistance from low-resistance or capacitance measurements. Available in the fourth quarter, expected pricing for the Fluke 289 is $529.95.
