Overview
This part of IEC 62057 applies to an automatic meter testing system (AMTS) permanently installed in a controlled environment. It covers the functions, technical requirements and acceptance methods of an AMTS. It also applies to a newly manufactured AMTS to test static active or reactive energy meters on 50 Hz or 60 Hz networks with an AC voltage up to 600 V (phase to neutral). This document defines the kind of AMTS that can continuously and automatically carry out all the test items specified in IEC 62058-31, including visual inspection, AC voltage test, no-load condition, starting current, accuracy and meter constant test. This document does not apply to: - data interfaces to the meter and test procedures of data interface; - industrial controllers, industrial personal computers, and servers supplied along with the AMTS. A typical application example is automatic meter testing systems (AMTS).
