1. Product Introduction
The DTSF/DSSF79-W1 electronic three-phase multifunctional energy meter is a modern and advanced instrument designed and manufactured using large-scale integrated circuits, digital sampling processing technology, and SMT technology, based on the actual electricity consumption of industrial users.
Its performance indicators comply with the technical requirements of GB/T 17215-2002 "Level 1 and Level 2 Static AC Active Energy Meters" and DL/T 614-1997 "Multifunctional Energy Meters" standards for multifunctional energy meters. The communication protocol complies with the "DL/T645-1997 Multifunctional Energy Meter Communication Protocol" and the special communication requirements proposed by the user.
This meter implements time-sharing measurement, sets daily automatic data transfer, programs and reads meters on handheld terminals or PCs, and displays on LCD screens. This meter can be set with 4 rates, 10 time periods, 2 time zones, and a 12 digit meter number, and has the function of outputting electric energy test pulses.

2. Function characteristics of DTSF/DSSF79-W1 electronic three-phase multifunctional energy meter
measurement function
