Introduction

This procedure based on JJF1002-2010 "national verification procedures write rules" establishment. This procedure reference GB/T 15284-2002 "tariff applications special requirements", GB/T 17215.211- 2006 "AC measuring equipment General requirements, tests and test conditions Part 11. Measuring Device", GB/T 17215.421-2008 "exchange fee measure control and load control - Part 21. Particular requirements for time switches Seeking "and JJF1245.6-2010" installed energy meter type evaluation outlining the special requirements meter functional class " And other standards for JJG 691-1990 "mind sharing degree (multi-rate) meter test procedures" have been revised. Compared with JJG 691-1990, in addition to editorial changes, the main changes in the technical part as follows. --- Procedure name from the original "time record of (multi-rate) meter" to "multi-rate watt-hour meter exchange"; --- Changes in the scope of this procedure is only applicable to a digital display time of the switch, and battery (Or capacitance) do work backup power tariff applications; --- For electronic multi-rate watt-hour meter and electrical multi-rate energy meter metering performance requirements are proposed; --- Revised test method for measuring daily timing error; --- Increasing the clock indication error test; --- Increasing the initial verification tests for Error indication of energy. The previous versions of this Recommendation published as follows. JJG 691-1990 "mind sharing degree (multi-rate) meter test procedures" Multi-rate AC electrical energy meter testing procedures

1 Scope

The order applies to the reference frequency of 50Hz or 60Hz AC power meter multi-rate (referred to as the multi-rate table) Initial verification and subsequent verification. The order applies to a digital display time of the switch, the power supply and do backup battery (or capacitor) Multi-rate tables. For multifunction meter with a time-measurement, the same verification procedure of the project implementation. This procedure does not apply to the field of multi-rate table test. 2. References This procedure refers to the following documents. JJG 307-2006 electromechanical AC power meter JJG 596-2012 electronic AC power meter JJG 597-2005 AC power meter testing equipment GB/T 17215.352-2009 AC measuring equipment - Specific requirements - Part 52. Symbols For dated references, only the dated edition applies to this procedure; undated reference documents Member, the latest edition (including any amendments) applies to this procedure.

3 Overview

Multi-rate tables, also known as time-measurement meter or multi-rate meter, which is provided with a plurality of counters, each counter and in Predetermined period of time corresponding to different rates of Implementation of work. Multi-rate tables mainly by energy measurement unit, clocked Unit, counters and other components. Counters may be an electromechanical device or a reservoir and a display by the group It can be stored into the electronic device and display information. A single electronic display, a plurality of electronic reservoir for use To form a plurality of electronic counters and. According to the principle of energy measurement unit, multi-rate table can be divided into electronic multi-rate tables and electromechanical multi-rate tables. Energy measurement unit electronic multi-rate table is constituted by a solid-state electronic components; electromechanical energy measurement single multi-rate table Yuan is the induction system measuring mechanism.

4 metering performance requirements

4.1 basic error Electronic multi-rate meter shall comply JJG 596-2012 4 metering performance requirements; Electromechanical Multi-rate tables should comply JJG 307-2006 3 metering performance requirements.
