High-Performance Industrial True-RMS Logging Multimeter
The Fluke 289 True-RMS Industrial Logging Multimeter is engineered to solve complex problems in electronics, plant automation, power distribution, and electromechanical systems. Featuring integrated TrendCapture technology, this advanced instrument graphically displays logged measurement data directly on its 50,000-count matrix screen without requiring a PC, enabling rapid analysis of intermittent anomalies and system downtime.
Industrial Use Cases
- Variable Frequency Drive (VFD) Diagnostics: Simultaneous accurate voltage and frequency measurements on adjustable speed motor drives using the selectable low-pass filter.
- Motor Winding and Contact Analysis: Measuring small differences in motor winding or contact resistance using the dedicated 50 ohm range with 1 milliohm resolution and 10 mA source current.
- Ghost Voltage Elimination: Safe testing of unenergized circuits without false readings using the low impedance LoZ Volts function.
