Overview
The OWON OWH9800 Series is designed for electrical power measurement and analysis. It features a 3.95-inch TFT display and adjustable update rates from 0.1s to 5s. Measurement functions include voltage, current, active power, apparent power, reactive power, power factor, frequency, crest factor, peak values, and THD. The instrument supports harmonic analysis with up to 63rd-order harmonics and provides integration measurements for Wh and Ah. Its RS232 interface supports SCPI and Modbus protocols for remote control, monitoring, and data logging.
