Fluke 345 Handheld Harmonic Clamp Meter
This power quality clamp meter combines the power of a power analyzer, power quality recorder and clamp meter to provide an ideal tool for monitoring electrical loads.
Thanks to the high-brightness color energy detector display for analyzing the harmonic spectrum, the low-pass filter for filtering high-frequency signal and noise, and the excellent electromagnetic anti-jamming design, the Fluke 345 energy analyzer is very suitable for maintenance and variable. The power quality of the load is faulty. In addition, with the energy meter, the Hall effect clamp meter can also measure DC current without interrupting the circuit.The built-in memory of the Power Analyzer allows users to record power quality parameters over long periods of time to analyze trends or intermittent problems.
Fluke 345 finished product application - Set up and troubleshoot variable frequency motors and UPS systems – check for normal power quality parameters to verify proper operation
- Harmonic Measurements – Finding harmonic problems that can damage or destroy critical equipment
- Inrush current capture – check for startup current when a suspected restart or annoying circuit trip occurs
- Load Analysis – Verify the capacity of the power system before adding load
| Features - AC/DC current: AC current (up to 1400 A) and DC current (up to 2000 A) without shutting down the circuit
- Meets the highest safety standards: 600 V CAT IV energy analyzer can be used at the inlet
- Accurate measurement in a signal-to-noise environment: Thanks to a low-pass filter, the clamp meter can make accurate measurements even if there is a distorted waveform in the electrical load
- Data logging: Any power quality parameter (including harmonics) can be recorded for a few minutes or even more than one month to detect intermittent faults
- Verify the battery: directly measure the DC fluctuation of the battery and DC system (%)
- Eliminate harmonic faults: Analyze and record harmonics in digital or graphical form
- Inrush current: capture and analyze annoying current fluctuations (3 seconds to 300 seconds)
- Easy to use: Wide backlit display for waveforms and trends for easy confirmation of power meter settings
- Three-phase power: built-in balanced load function
- View graphs and generate reports: Use the power analyzer with the included power logging software
