Introduction
This procedure based on JJF1002-2010 "national verification procedures write rules" establishment.
This procedure reference GB/T 17215.301-2007 "multifunction energy meter special requirements", GB/T 17215.211-
2006 "AC measuring equipment General requirements, tests and test conditions Part 11. Measuring Device",
JJF1245.6-2010 "installation of energy type evaluation outlining the special requirements meter functional class" and
JJG 780-1992 "Digital AC Power Meter" and other technical specifications, for JJG 569-1988 "maximum demand meter
(Meter) Trial test procedures "have been revised. Compared with JJG 569-1988, in addition to editorial changes to the Main
Technical changes are as follows.
--- Scope changes, for three-phase electronic energy meter maximum demand, the maximum does not apply to electromechanical
Demand Meter;
--- Basic error, creep, start, constant, AC voltage tests according JJG 596-2012 execution;
--- Increased day clock timing error, the clock indication error test project, canceled the demand cycle test project;
--- Increased demand indication error requirements.
The previous versions of the release JJG 569 case.

Maximum demand meter testing procedures
1 Scope
The order applies to the reference frequency of 50Hz or 60Hz three-phase electronic energy meter maximum demand (referred Demand
Table) initial verification and subsequent verification.
For multifunction meter with a measurement of maximum demand function, the same verification procedure of the project implementation.
This procedure does not apply to on-site inspection and the need to scale electromechanical scale required verification.
2. References

3 Overview
Demand is an average of a predetermined time interval in the power, which is the expression of formula (1).
P =
T0∫
T0
p (t) dt (1)
Where.
p --- instantaneous power, kW;
T0 --- billing cycle, min;
Average active power P --- T0 time, that demand, kW.
Scale required by the energy measurement unit and data processing unit, etc., can simultaneously measure the three-phase active energy and maximum demand
the amount. Maximum demand refers to demand the maximum period or the recorded billing period prescribed.
Scale works need to issue at the beginning or end of each billing cycle by the time base circuit set billing cycle
A control signal to obtain a set billing cycle current demand, the demand and maximum demand values recorded in the memory phase
Compare, if more than the memory of maximum demand, to replace the memory of the original data, complete the maximum demand recorded.
4 metering performance requirements
4.1 basic error
Scale should meet the needs JJG 596-2012 4.1 requirements.
4.2 Creeping
Need to comply with the requirements JJG 596-2012 scale of 4.2.
