TesterMeter-ETCR8300A Clamp on Leakage Current Monitoring Recorder
Ⅰ. INTRODUCTION
TesterMeter-ETCR8300A Series Three-Channel Current/Leakage Monitoring Recorder is well designed and manufactured for online measurement, monitoring and recording of Three-Channel AC leakage / current at the same time. It is composed of a tester, monitoring software, current clamp and communication cable, etc. This instrument has been widely applied the 380/220 Power system. It can provide a safety and convenience measurement with accurate results. The instrument has a large LCD display with blue background and a large storage space. 3900 sets of data can be stored in the instrument. Three- channel current value can be display on the screen. In addition, the instrument can automatically store data at a interval, which is adjustable from 1 to 99 min. Monitoring software provides online and real-time monitoring and historical data inquiry. With the software developed by our technical department, the users can read, inquire, store, generate and print a fitting curve and report. The current clamp is made of a special alloy, adopts the latest CT technique and magnetic shielding technique and is not almost interfered by external magnetic field. This ensures high accuracy, high stability and high reliability of the values which are measured continuously. |
