1 Scope
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).
NOTE The controlled environment refers to places that meet the test requirements of meters.
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.
