Product Introduction
ETCR EM8300A Three Channel Clamp Current Monitoring Recorder, also known as leakage current recorder and multi-channel current recorder, is used for on-site online simultaneous monitoring and recording of 1 to 3 AC currents or leakage currents, fault finding, and line maintenance.The instrument consists of a recorder host, a current clamp, a charger, data upload software, a communication line, etc., and can be widely used in 380/220V power systems to provide safe, accurate and convenient power instruments for power inspectors.
The host of the ETCR8300A Three Channel Clamp Current Monitoring Recorder adopts LCD display, and the three channels are displayed on the same screen, which is clear at a glance. There are two options for Chinese operation interface and English operation interface, which are suitable for engineers and technicians in different countries.The recorder uses a large-capacity rechargeable lithium battery, and the battery life can continue to record for up to 7 days.It has a system clock function and large storage space, can set the monitoring and recording time on site, can store 200,000 sets of data, has an automatic storage interval setting function, and the recording period is set from 1 second to 99 minutes.Equipped with a USB communication interface, the data upload software has the functions of reading, reviewing, saving, and reporting historical data.
1. The current clamp is made of permalloy and adopts double-layer magnetic shielding technology, which is almost unaffected by the external magnetic field, ensuring the high precision, high stability and high reliability of uninterrupted monitoring all year round.
2. The host can be configured with 1 to 3 current pliers, and users can choose the type according to their needs.
3. The recording interval can be set.
4. Storage function, large storage space for 200,000 sets of data.
5. Rechargeable lithium battery, which works continuously for about 7 days in power-saving mode, and data will not be lost when the battery is replaced.
6. USB communication interface.
