Metrel MI2885-EU Master Q4
The MI 2884 Master Q4 is an ideal troubleshooting tool designed to automatically record all important data and waveforms of voltage events like Dips and Swells. Users can set seven optional triggers for capturing waveforms of selected quantities. A large, easy-to-read graphical colour display enables the detection of harmonics, phasors, and waveform anomalies simply by connecting the device.
The instrument features handy "Quick Set" buttons for faster data overview and is designed for both long-term recording and troubleshooting in three-phase and single-phase power distribution systems. The advanced PowerView3 software package enables detailed analysis, direct reading from the microSD card, and automatic creation of professional test reports.
