Fluke 289 True RMS Multimeter
Designed for complex industrial troubleshooting, the Fluke 289 True RMS Multimeter combines true RMS measurement with onboard data logging for electronics, plant automation, power distribution and electro-mechanical equipment. A 50,000-count, 1/4 VGA dot-matrix display provides a white backlight and multiple on-screen displays for viewing measurements. TrendCapture plots logged data directly on the meter, while 14x zoom supports closer review without requiring a PC.
Expanded memory supports unattended signal monitoring and stores up to 15,000 recorded events, with multiple logging sessions saved before download. A low-pass filter supports voltage and frequency measurements on adjustable-speed motor drives and electrically noisy equipment, while LoZ helps eliminate ghost-voltage readings. The two-terminal 50 Ω function provides 0.001 Ω resolution with a 10 mA source current for comparing motor winding or contact resistance, while peak capture records transients as fast as 250 μs.
