Product Introduction

The ETCR EM8400 single-phase power recorder is used to monitor and record the operating voltage, current, frequency, and power of a single-phase power source over a period of time. It supports two input channels (one voltage and one current) and can be connected to a computer via USB to download the recorded results for data storage and analysis. The recorder consists of a main unit, current clamp, power adapter, communication cable, and data upload software. It can be widely used for fault diagnosis and line maintenance in 380/220V power systems, providing electrical inspectors with a safe, accurate, and convenient power instrument.

The main unit features an LCD display that simultaneously shows real-time test data for one channel, including operating voltage, current, frequency, and power. It offers both Chinese and English user interfaces to suit engineers from different countries. The recorder uses a high-capacity rechargeable lithium battery with a five-bar battery indicator, providing up to two days of continuous recording with the screen off. Featuring a system clock function and large storage space, this device allows for on-site setting of monitoring and recording times, storage of 200,000 data sets, and automatic recording interval setting, with recording periods adjustable from 1 second to 99 minutes.
