1.0 Foreword
MeterBuddy 2.2, The Program Tool of Libra Meter, obey ANSI C12.18-1996 ,C12.19-
1997 .
The software is used to debug, test, read and program the Libra Meter. This is a full
version which includes all function. When it is provided to end-user, we will publish
a simple version which incluses basic function.
This document applies to the implementation of an ANSI C12.19 Standard Sub Set
inLIBRA_WASION _Meter AMR Test tool - MeterBuddy.
(LIBRA_WASION_Meter is an upgrade version of the Libra Meter, Designed for LIBRA
IEC Meter Project, so the MeterBuddy can be used to Test LibraI , LibraII and Libra III)

Because the BaudRate of two kinds of ports are different, so you should make some
changes as below.
1) Remote or Local IR
2) PLC Port (UART port of AMR/AMI module)
Other Settings:
Libra-1,3 seris can only support Local Optical Port, Libra-2 seris can support
both Local and Remote Optical port. You should select the optical type before
you connect MeterBuddy to meter.

When you use Remote Optical Port or RS485 connect to meter, you should set
the meters Address here.
The Address is the last two digits of the meter ID which is printed on the
Nameplate of meter.
When you connect to a meter (include LibraDigiEth card) via Ethernet (or Ethernet
+ Zigbee Mesh Network), you should input the meter’s IP Address and TCP port.

6.5 Demand
Demand operation includes setting parameter, reading Demand data and Deman-
reset which can be executed in Normal Mode or Test Mode.
 Demand data is transported in the format dictated by ANSI C12.19.
 Meter can be measured maximum active demand and date and time of EVENT,
Cumulative demand, maximum demand of 4 rates and data and time, sub-
interval time, etc.
 Demand data support rewritable
 The meter can be recalculated in accordance with the new set of parameters
automatically
 Demand and the clock synchronization
6.5.1 NORMAL MODE
6.5.1.1 Demand setting parameters.
This table is used to set demand working parameters. The meaning of parameter
dictated by ANSI C12.19 Table 13- Demand Control Table. Demand Control, is used
to specify information affecting demand, such as interval size, reset exclusion, etc.
Notes: If no special requirements , the above four parameters, generally do not need
to set. If the meter to detect the error about parameters of the demand , it will
initialize the parameters to default values. the default value is 0.
 Sub_Int, for Sliding demand, the value of minutes in the sub-interval. The value
is set from 1 to 15.
 Int_Multiplier, for Sliding demand, minutes of multiplier.
 Valid Demand Interval Length/Interval Multiplier Combinations
The valid interval lengths appear in the first column; interval multipliers are
listed across the top row. The intersection of any row/column will show a valid
subinterval size or '√' to indicate that the combination is supported.

 [Tables 30 & 31- Dimension Limiting & Actual Display ] give a detailed description
on LCD display dictated in ANSI C 12.19.
 [Table 32 – Display Source],This table contains manufacturer-defined display
sources. The size of this table is limited by memory availability; therefore, it
must be programmed with the subset (maximum of 64 sources) of display
sources actually referenced in Table 33, rather than the complete set of defined
sources.
Notes: See Chapter 6.7.3 of ’Libra3C handbook.doc’ for a complete list of items
available for display (MENU_ID).
LCD Menu can be programmed by Meterbuddy, there are 2 tables which are used for

 Items,Refer to “Libra-3cV1.0 Mutifunction Meter Handbook.pdf” chapter 2.3.4.
 Format, It is used to define the display format of quantity.
 Mode, Normal Mode,Alternate Mode,Test Mode can be set one by one. Either of
the two modes which are Normal Mode and Alternate Mode must be given.
For example,user need to set 3 screens of Normal Mode, 5 screens of Alternate
Mode, And 2 screens of Test Mode. All Form are [03].Values of ID &Items are be

7.0 Time Of Use
7.1.1 Overview
MeterBuddy supports to program Time Of Use(TOU), such as Real Time Clock,TOU
Control,Non-Recurring Calendar, Fixed-Recurring Calendar and Schedule. This
chapter takes several examples to discribe that how to program TOU.
 The maximum total number of dates supported is 32, distributed between
recurring and non-recurring dates as desired. The meter require that the dates
be sorted(Small to large)
 Tier switches must be sorted. Tiers must be grouped by daily schedule ID's and
sorted by time within each ID group.
 TOU support maximum : 8 non-recurring dates, 32 recurring dates, 64 tier
switches( each DAILY_SCHEDULE_ID_MATRIX include 4 schedule tiers ),4
changed seasons, 4 day-type, 1 special schedule, 4 schedule
tiers(PEAK,BASE,REDUCE,VALLEY).

 Number of Days, the value is calculated automatically .
Libra-3L meter optional recorder is capable of handling 42 days of 15 minute
load profile data on four channels with 32K or 42 days of 15-minute load profile
data on 15 channels with 128K bytes of memory. The number of days of
capacity is dependent upon the interval length duration and the number of
channels used.
 Number of Intervals per day , max intervals based on interval length, the
value is calculated automatically .
 Number of Channels, 1~16channels can be set.
 Interval lengths , Load Profile interval lengths include, 1, 5, 15, 30 and 60
minutes. Each interval consists of two bytes.
The register records up to 15 channels of load profile data. The number of
channels is programmable. The available memory is distributed equally among
each channel.

Libra-3L meter optional recorder is capable of handling 42 days of 15 minute load profile data on four channels with 32K or 42 days of 15-minute load profile data on 15 channels with 128K bytes of memory. The number of days of capacity is dependent upon the interval length duration and the number of channels used.  Number of Intervals per day , max intervals based on interval length, the value is calculated automatically .  Number of Channels, 1~16channels can be set.  Interval lengths , Load Profile interval lengths include, 1, 5, 15, 30 and 60 minutes. Each interval consists of two bytes. The register records up to 15 channels of load profile data. The number of channels is programmable. The available memory is distributed equally among each channel. 10.3 Program Parameters to meter The reader/programmer inputs 15 to Interval Length value,then clock [Progam Current Cell].
