Overview
The MI 2992 is a handheld three-phase power quality analyser with a 10.1” TFT colour touchscreen. It provides quick, guided setup for on-site measurements and supports both long-term recording and troubleshooting workflows. The instrument performs live measurements, historical data review and comprehensive on-device analysis for power quality assessment.
