Microtest 7140 100kHz AC/DC Single-Phase Power Analyser/ Meter

Description

Microtest 7140 100kHz AC/DC Single-Phase Power Analyser/ Meter

MICROTEST 7140 is designed for single-phase AC/DC power measurement and analysis, featuring a 0.2Hz–100kHz bandwidth, 500kSPS sampling rate, and ±0.05% accuracy. Its compact design includes a 4.3” TFT LCD for numeric and graphical displays of key power parameters. With 800V/30A direct input and 100th-order harmonic analysis, it enables simultaneous harmonic and integration measurements, boosting efficiency. For standby power testing, it offers a 5mA range, 10μW resolution, and supports waveform, bar, and trend charts. Meter mode displays 4, 8, or 16 parameters with real-time min/max tracking, while comparison mode provides PASS/FAIL evaluation.
