With the ability to log data and review it graphically on-screen, you can solve problems faster and help minimize downtime.
Equipped with new functionality, the Fluke 289 has a large 50 000 count, 1/4 VGA dot matrix display with white backlight. The logging function has expanded memory for unattended monitoring of signals over time. Using on-board TrendCapture, users can graphically review logged readings without needing a PC and store up to 10 000 readings over time. You can also save multiple logging sessions before pc download is necessary.
The multimeter has a two terminal 50 ohm range with 1 milliohm resolution, 10 mA source current. It is useful for measuring and comparing differences in motor winding resistance or contact resistance. A low pass filter ensures accurate voltage and frequency measurements on adjustable speed motor drives and other electrically noisy equipment. A low impedance voltage function eliminates ghost voltages, also recommended when testing for absence or presence of live power.
Other functions include:
- Real time clock for automatic time stamping of saved readings
- Relative mode to remove test lead resistance from low ohms or capacitance measurements
- True-rms ac voltage and current for accurate measurements on non linear signals
- Measure up to 10 A (20 A for 30 seconds)
- 100 mF capacitance range
- Peak capture to record transients as fast as 250 µs
- Withstands hazardous 8 000 volt spikes caused by load switching and faults on industrial circuits and complies with second edition IEC and ANSI electrical safety standards.
- Optically isolated communication port for transferring data to pc (usb cable and software optional)
