1.1 Meter Overview
Powerful Multifunction Power Meter
The Acuvim II series multifunction digital power meter is designed using modern MCU and DSP technology. It integrates three-phase energy measuring and displaying, energy accumulating, power quality analysis, malfunction alarming, data logging and network communication. A vivid LCD display with large characters and, time of use programmable backlight provides a clear realtime data readout.
An Ideal for Electric Automation SCADA Systems
The Acuvim II series meter is the ideal choice for replacing traditional, analog electric meters. In additon to providing clear real-time readings on the meter front, it can also be used as a remote terminal unit (RTU) for monitoring and controlling for a SCADA system. Users can access all measurement parameters via the standard RS485 communication port (or the optional Ethernet port) with the ModbusTM protocol.
Energy Management
The Acuvim II series meter is able to measure bidirectional, four quadrants kWh and kvarh. It provides maximum/minimum records for power usage and power demand parameters. All power and energy parameters can be viewed remotely via software in order to easily monitor various parameters. In addition, measurement tables can be viewed from the free Acuview software.
Remote Power Control
This meter is designed for measuring and monitoring power quality parameters. Since different I/O modules can be added to the meter, this expands the capabilities and provides a very flexible platform for using the meter as a distributed RTU, for metering, monitoring and remote controlling, all in one unit.

Power Quality Analysis
Utilizing digital signal processing (DSP) technology, the Acuvim II series meter provides high accuracy power quality analysis and supports remote monitoring via the Ethernet module. The meter continuously updates metering results and allows users to access the meter online to monitor parameters such as voltage and current THD, harmonics, voltage crest factor, current K factor, and voltage and current unbalance factor etc.
Data Logging
The Acuvim IIR/IIE/IIW meter contains 8 megabytes of onboard memory for data logging and historical trending. Since the meter contains a real-time clock, all events and logged data will be time stamped.
Time of use (TOU-Acuvim IIE)
User can assign up to 4 different tariffs (sharp, peak, valley and normal) to different time period within a day according to the billing requirements. The meter will calculate and accumulate energy to different tariffs according to the meter’s internal clock timing and TOU settings.
Power Quality Event Logging
When a power quality event happens, such as voltage sag and swell, etc, Acuvim IIW will record the timestamp and the triggering condition of the event. It can save up to 50, 000 power quality events.
Waveform Capture
Acuvim IIW contains another 8 megabytes of on board memory for power quality event logging and waveform capture. Acuvim IIW can record 100 groups of voltage and current waveforms. It logs at 64 points per cycle. It provides the waveform record of 10 cycles before and after the triggering point. It also supports a settable triggering condition.

2.3.6 Communication
Acuvim II series meter uses RS485 serial communication and the ModbusRTU protocol. The terminals of communication are A, B, and S (14, 15, 16). A is differential signal +, B is differential signal - and S is connected to the shield of the twisted pair cables. Up to 32 devices can be connected on a RS485 bus. Use good quality shielded twisted pair cable, AWG22 (0.5mm2) or higher. The overall length of the RS485 cable connecting all devices should not exceed 1200m (4000ft). The Acuvim II series meter is used as a slave device of masters such as a PC, PLC, Data Collector or RTU.
If the master does not have RS485 communication port, a converter (such as a RS232/RS485 or a USB/RS485 converter) will be required. Typical RS485 network topologies include line, circle and star (wye). The shield of each segment of the RS485 cable must be connected to the ground at one end only.
Every A(+) should be connected to A(+), B(-) to B(-), or it will influence the network, or even damage the communication interface.
The connection topology should avoid “T” type which means there is a new branch and it does not begin from the beginning point.
Keep communication cables away from sources of electrical noise whenever possible.
When using a long communication cable to connect several devices, an anti-signal reflecting resistor (typical value 120Ω-300Ω/0.25W) is normally added to the end of the cable beside the last meter if the communication quality is distorted.
Use RS232/RS485 or USB/RS485 converter with optical isolated output and surge protection.

Yes: Alarm enable; No: Alarm disable It can be selected as cue signal for alarming. Yes: backlight flashes upon alarm condition; No: no backlight flashing
There are 16 alarm channels available. Each channel is controlled and enabled 1 bit each from a 16-bit register. Bit value of 1 means that the corresponding alarm channel is enabled whereas 0 means that the channel is disabled. The meter will display the value of this 16-bit register in decimal numbers (for different channel combination). For example, 00000 means that all channels are disabled; 00001 means only the first channel is enabled; 65535 means that all channels are enabled. Refer to section 4.4 on page 65 for more details.
"AND" logic relationship can be set among channels. When an "AND" logic is in place, both channels have to be triggered before the meter sends out the alarm signal. The logic can be set according to the predefined rule (refer to section 4.4 for more details). User can setup up to 8 logic relationships for alarming. Each logic relationship is controlled and enabled 1 bit each from a 16-bit register (only the lower 8 bits are used). Bit value of 1 means that the corresponding logic relationship is enabled whereas 0 means that the relationship is disabled. The meter will display this 8-bit value in decimal numbers (for
different relationship combination). For example, 000 means that all relationships are disabled; 001 means only the first relationship is enabled; 255 means that all relationships are enabled.
When DO1 works in alarming mode, a 16-bit register is used to control which channels are associated with this output. Similar to the alarm channel selection, this 16-bit value is expressed in decimal when reading on the meter front. For example, 00000 means that no alarm channels are associated to this output; 00001 means that alarm channel 1 is associated to DO1; 65535 means that all alarm channels are associated to DO1. Refer to
section 4.4 for more details.
If 2 AXM-IO2 modules are attached to the meter, DO1 and DO2 denote to the first and the second DO channel of AXM-IO21; DO3 and DO4 denote to the first and the second DO channel of
AXMIO22 respectively. DO2, DO3 and DO4 use the same setup method as DO1.

Chapter 4 Detailed Functions and Software
The Acuvim II series meter contains advanced metering tools and is able to measure a multitude of power, energy and power quality parameters. Some advanced functions may not be accessible directly from the meter front; therefore, every meter comes with a powerful software that helps access the information. This chapter introduces these functions and the software.
4.1 Basic Analog Measurements
Acuvim II series meter can measure voltage, current, power, frequency, power factor, demand, etc. With high accuracy, as shown via the software below:
Fig 4-1 Real-Time Metering

Demand:
This meter consists of several types of demand calculation: total active power demand, total reactive power demand, total apparent power demand, phase A current demand, phase B current demand, and phase C current demand. When demand is reset, demand memory registers are set as 0.
Demand calculating mode can be set as sliding window and thermal according to user. The Fig 4-7 shows how it works.
When using the sliding window interval method, user selects an interval from 1 to 30 minutes, which is the period of the calculation. The demand updates every 1 minute as the window slides once.
Thermal demand method calculates the demand based on a thermal response which mimics a thermal demand meter. User selects the period for the calculation and the demand updates at the end of each period.
Energy:
This meter measures and accumulates energy in different directions (import and export). For real-time energy monitoring, it accumulates energy for kWh, kvarh and kVAh continuous (since its last reset).
Calculating mode
1. User can select different energy calculating modes, fundamental based or full-wave based either from the meter front or via communication. Fundamental based calculating is used to accumulate energy without taking harmonics into consideration while full-wave based calculating is used to accumulate energy including fundamental and harmonics.
Note: 1) When fundamental based calculating mode is selected, PF calculation will be based on the fundamental wave.
2)When selecting 400Hz type, only support full-wave.
2. There are two ways to calculate reactive energy (power)
Mode 0: real reactive energy Mode 1: general reactive energy
3. User can choose primary energy or secondary energy either by pressing keys from the meter front or via communication as shown in Fig 4-7.

Current direction adjustment
Under normal circumstances, current flows from input terminal 1 to terminal 2 (i.e. from I11 to I12 for phase A current); however, current may flow in the opposite direction due to incorrect wiring setup. Instead of rewiring the system, the meter provides users an option to reverse the polarity of the current. By default, current direction is set as "positive", to reverse the current polarity by 180 degrees, user can set current direction as "negative". Refer to Fig 4-7 for more details.

4.2 Max/Min
Acuvim II series meter logs maximum and minimum value statistics for phase/ line voltages, current, power, reactive power, apparent power, power factor, frequency, demand, unbalance factor, THD as well as the time they occur. All data is stored in non­volatile memory so that statistic information can be preserved even when meter is shut off. All maximum and minimum data can be accessed via communication or from the meter front but time stamps can only be accessed via communication. Statistics can be cleared via communication or from the meter front.
4.3 Harmonics and Power Quality Analysis
1. Harmonics
Acuvim II series meter can measure and analyze THD, harmonics support 2nd to 63rd, even HD, odd HD, crest factor, THFF, K factor etc. They are shown in Fig 4-2.
Note: When selecting 400Hz type, only support 2nd~15th harmonics;
2. Phase angle
Phase angle indicates the angle between phase A voltage and other voltage/ current parameters. Angle ranges from 0 to 360 degrees. This function is to help users find out the relationship between all input signals avoiding wrong wiring. When it is set to “2LL” or “3LL”, it gives out the phase angles of u23, u31, i1, i2, i3 corresponding to u12. When it is set to “3LN”, it gives out the phase angles of u2, u3, i1, i2 and i3 corresponding to u1. When it is set to “1LL”, it gives out the phase angles of u2, i1, i2 corresponding to u1. They are shown in Fig 4-4.
3. Sequence component and unbalance analysis
Acuvim II series meter is able to perform sequential analysis for the input signal. It looks at the positive sequence, negative sequence and zero sequence of 73 the fundamental frequency and performs unbalance analysis for voltage and current. Sequence components are shown in Fig 4-4, unbalance of voltage and current are shown in Fig 4-
1.

4.4 Over/Under Limit Alarming
Acuvim II series meter has over/under limit alarming capabilites. When the monitored parameter goes over/under the preset limit and stays at the level over the preset amount of time delay, the over/under limit alarm will be triggered. The over/under limit value and its time stamp will be recorded in the 74-alarming log. The meter can record up to 16 alarming records. When extended I/O modules are attached, digital outputs (DO) and relay outputs (RO) can be triggered upon alarm conditions and used to activate downstream devices such as a beacon light or a buzzer.
Before using the alarming function, alarm conditions such as logic dependency, target setpoint, time delay etc must be set correctly. Settings can be accessed and modified from the software via communication connection as shown in Fig 4-5.

Parameter code: select target parameter for alarm monitoring for example: 0-frequency, 44­AI4 sampling data.
Comparison mode: set alarming condition 1: greater than, 2: equal to, 3: smaller than. For example: if you choose target parameter to be "frequency", condition to be "greater than" and setpoint to be "50", alarm will be triggered when the frequency is greater than 50Hz.
Note: setpoint value is the same as the actual value of the selected parameter.
Delay time: If the alarms condition lasts for the preset time period, the alarm signal will be
triggered. The delay range is from 0 to 3000 (unit: 10ms). When it is set to 0, there is no delay, alarm will be triggered when the alarm condition is met. If it is set to 20, there will be a 200ms (20 x 10ms) delay. Output to relay: 0-alarming signal will not be sent to RO; if it is set as 1 and AXMIO11 is connected, it will output to RO1 when alarm triggers. RO1 will be turned off when all alarms output to RO1 are cleared. RO2~RO8 work in the same manner as RO1.
Note: 1) If RO is under alarming mode, it can only work in “latch” mode. 2) If the number is 51~79, there are special guide for contrast method and meaning of parameters, please refer to Chapter 6. After setting up the alarming parameters, user must also setup the global settings in order for the alarm to work properly.
2. Global settings
Register addresses for global alarm settings are from 1046H~104DH. Please refer to section
5.3, page 95 "Global alarming settings" for more details.
“Global alarming enable” determines whether the alarming function of the meter is activated or not. The alarming function is enabled when it is set as "1".
When “Alarming flash enable“ is set as “1”, backlight will flash when alarm is triggered.
“Alarming channel enable setting” determines whether the corresponding alarm group is enabled or not. There are 16 groups in all and each one is corresponding to one bit of a 16­bit register. The corresponding bit must be set to "1" in order to activate the alarm channel.
Logic "AND" between alarm setting: The 16 alarming records in the meter are divided into 8 pairs. Each pair has two alarm groups. The two groups can be logically “AND” by controlling the logic check box. When two groups are “AND”, alarming triggers only if both AND conditions are met. If the "AND" logic box is unchecked, the two alarm channels will work independently.

The 8 "AND" logic pairs are arranged as follows: 1st, 2nd channel form Pair 1; 3rd, 4th channel form Pair 2; 5th, 6th channel form Pair 3; 7th, 8th channel form Pair 4; 9rd, 10th channel form Pair 5; 11th, 12th channel form Pair 6; 13th, 14th channel form Pair 7; 15th, 16th channel form Pair 8.
This function is controlled by the lower 8 bits of the 16-bit register and each bit is corresponding to a pair. “1” means this function is enabled and “0” means disabled.
“Alarming output to DO1 setting”: When “Digital output mode” is set to “1”, DO1 can be used as alarming output. A 16-bit register is used to perform this function, its bit0~bit15 correspond to the 1st ~16th group respectively. When the related I/O module is connected and is under alarming mode, and if the corresponding bit is set to 1 and the alarming condition is met, alarm signal will be sent to DO1. DO1 will be turned off when all alarms correspond to DO1 are cleared. If related bit is set to 0, that alarm channel will not issue alarm signal to DO1. DO2~DO4 work in the same manner DO1.
After completing the setup steps correctly, alarming function can be used.
3. Setting Example
Here is an example showing how to apply the logic "AND" function for a pair of alarm channels.
The conditions are as follows: I1 greater than 180A, delay 5s for the 1st alarm channel; U1 less than 9980V, delay 10s for the 2nd alarm channel. No alarm signals will be sent to outputs. The CT primary value of I1 is 200A, and CT2 is 5A. The PT ratio for U1 is 10000:100. The following shows how all the related registers are to be set.
Settings of first group:
“Parameter code (104EH)” is set to 9, which stands for I1. “Comparison mode (104FH)” is set to 1, which stands for "greater than". “Setpoint value (1050H)” is set to 4500, according to the relationship between actual
value and communication value (I=Rx * (CT1/CT2) /1000). 78 “Delay time (1051H)” is set to 500, so the actual delay time is 500*10ms=5s. “Output to relay (1052H)” is set to 0, because there is no output to RO.
Settings of second group:
“Parameter code (1053H)” is set to 1, which stands for U1. “Comparison mode (1054H)” is set to 3, which stands for "smaller than".

Global settings:
“Alarming channel enable setting (1048H)” set to 0003H to enable the first and the second channel. “Logic "AND" between alarming setting (1049H)” set to 0001H to enable logic "AND" in Pair 1. “Alarming output to DO1 setting (104AH)” set to 0, since no output to DO1. “Alarming output to DO2 setting (104BH)” set to 0. “Alarming output to DO3 setting (104CH)” set to 0. “Alarming output to DO4 setting (104DH)” set to 0. “Alarming flash enable (1047H)” set to 0 to disable backlight flashing when alarming occurs. “Global alarming enable (1046H)” set to 1 to enable over/under limit alarming.
4. Records of Alarming Event
Acuvim II series meter has built in alarm logging capabilities. 16 entries can be recorded in total. The record sequence of these entries do not depend on the sequence of the 16 alarm channels. The meter begins logging alarm status starting from the 1st record location to the last one. Alarm logs are being recorded in a "cycle" fashion which means the latest event will overwrite the oldest record. When over/under limit parameters return to normal, its value and time stamp will be recorded as well. Therefore, users can determine the over/ under limit duration by checking the time difference.
Here is the 1st group of records. Other groups of records have the same format.

“Alarming status” indicates information of current alarm status. It is a 16-bit unsigned integer. Parameter code is stored in the higher 8 bits. Bit1 indicates whether logic "AND" is enabled or not, 1 means enabled and 0 means not. Bit0 indicates whether alarming has occured or recovered, 1 means occurred and 0 means recovered. Undefined bits are 0.
“Parameter code” specifies the monitored parameter.
“Value” shows the recorded value of the selected parameter when an alarm is triggered and when it recovers.
“Time” indicates the time stamp with the accuracy in milliseconds (ms).
Alarming event will set bit0 of “system status (102EH)” to be 1. When software sends clear alarm command, Bit0 of “system status (102EH)” will be set to 0.
Alarming group number (1032H): the range is 0~16, 0 is no alarm record, and others stand for which record is newest alarm. Alarming group number can be saved during meter power off, and it is cycling recording.

4.5 Data Logging
The Acuvim IIR/IIE/IIW meter provides data logging that records the data at a set interval. This meter has 8 MegaBytes of memory which gives it extensive datalogging capabilities. It has a real-time clock that allows logs to be time-stamped when log events are created.
1. Data log settings
The Acuvim IIR/IIE/IIW meter has three sets of historical data logs. Each log can be independently programmed with individual settings, meaning that each can be used to monitor different parameters. You can program up to 117 parameters per log. You also have the ability to allocate available system resources among the three logs, to increase

Having three sets of historical logs provides you with the option of programming each log with unique parameters. For example, you can program Historical Log 1 to record measured values parameters (for example, Frequency, Voltage, Current), Log 2 to record energy values parameters, and Log 3 to record power quality parameters. Historical Log parameters can be selected from the following thirteen groups:
• Real-Time Metering (Frequency; Instantaneous Voltage; Instantaneous Current; Total and Per Phase Power and Power Factor; Neutral Current; unbalance V/I; load type; Current demand; and Per Phase/ Total Power demand)
• Energy (Ep_imp; Ep_exp; Ep_total; Ep_net; Eq_imp; Eq_exp; Eq_total; Eq_net; Es; Epa_imp; Epa_exp; Epb_imp; Epb_exp; Epc_imp; Epc_exp; Eqa_imp; Eqa_exp; Eqb_imp; Eqb_exp; Eqc_imp; Eqc_exp; Esa; Esb; Esc)
• THD Volts AN/AB (THD, 2nd -63rd Harmonic Magnitudes, ODD, EVEN, CF and THFF of Volts AN/AB)
• THD Volts BN/BC (THD,2nd -63rd Harmonic Magnitudes, ODD, EVEN, CF and THFF of Volts BN/BC)
• THD Volts CN/CA (THD, average THD, 2nd-63rd Harmonic Magnitudes, ODD, EVEN, CF and THFF of Volts CN/CA)
• THD IA (THD, 2nd-63rd Harmonic Magnitudes, ODD, EVEN, KF of IA)
• THD IB (THD, 2nd-63rd Harmonic Magnitudes, ODD, EVEN, KF of IB)
• THD IC (THD, average THD, 2nd-63rd Harmonic Magnitudes, ODD, EVEN, KF of IC)
• Sequence Component (positive, negative and zero sequence)
• Phase Angles (the angle between U1 and other voltage and current parameters.)
• DI Counter (the DI numbers of the IO modules)
• AO/AI Raw Value (the AO output register values and the AI sample register values)
• AO/AI Value (the AO output values and the AI sample values)
The following procedures show how to select and store parameters in historical log 1. The Group field determines the items that are available for selection.

1) Select a Group. The possible selections are: Real-Time Metering, Energy, THD Volts AN/AB, THD Volts BN/BC, THD Volts CN/CA, THD IA, THD IB, THD IC, Sequence Component, Phase Angles, DI Counter, AO/AI Raw Value and AO/AI Value.
2) Select items for your log: a. Highlight the parameter(s) you want to log into the meter's memory. b. Click Add to add the parameter to the Selected Parameter Area. c. To remove parameter(s), highlight them in the Selected Parameter Area and click Remove.
3) Set the logging interval (in minutes). Interval can be set from 0 - 1444 minutes according to different application.
The logging interval determines when the meter takes a snapshot. When interval is set as 0, the set of historical data log is disabled.
4) There are 100 sectors in total for the 3 historical data logs. User can assign different sector size to each log according to different applications (as long as the total sector sizes of the 3 logs do not exceed 100).
5) Three Modes of historical log:
A. Mode1: if correctly set historical log, can record without setting date and time, depending on first-in first-out recycling log.
B. Mode2: if correctly set historical log, as set date and time, can record within begin to end time. Record will stop after buffer is full.
C. Mode3: if correctly set historical log, as set hour and minute, only can record while the running time is equal to setting hour and minute, depending on firstin first-out recycling log.
NOTES:
• If the memory of the historical data log is full, the meter will erase the first sector in which the memory size is 65536 bytes (64kb). The following sector (the second sector) will become the first sector and the data from the erased sector will not be recoverable. Therefore, user should save the whole log before memory is full to maintain all the data.
• There are two display fields at the bottom of the data log setting screen. They show the registers in the logs, the total bytes used and the bytes remaining for this historical log. These fields are updated as you make selections on the screen. The total number of bytes available per log record is approximately 234.

2. Retrieving logs
There are two ways of retrieving the logs: "read one window" and "read all". The retrieval screen is shown in Fig 4-9.
Fig 4-9 Retrieval screen
The "read one window" method allows you to access and read a specific log location at an offset from the first log. The "window record num" is the maximum number of record entries the software can read at a time, it is calculated by 246 / Record Size. The larger this number is, the faster data can be retrieved. Log type is the logs you want to retrieve, for example, log type 0 is data logging 1, log type 1 is data logging 2 and log type 2 is data logging 3. The "read all" method accesses and reads the historical data log automatically, the offset increases automatically until all the logs are retrieved.
The data logs contents are shown at the bottom of the page.

4.6 Time of use (TOU)
User can assign up to 4 different tariffs (sharp, peak, valley and normal) to different time period within a day according to the billing requirements. The meter will calculate and accumulate energy to different tariffs according to the meter’s internal clock timing and TOU settings.
TOU setting: User can set a maximum of 12 TOU seasons, each season can be assigned to a TOU schedule (a maximum of 14 TOU schedules are available). Each schedule can be divided up into 14 segments (in which each segment can have its own tariff). User can customize the TOU calendar (including its tariffs, seasons, schedules and segments) according to different applications. To make sure that the TOU calendar is setup correctly, the meter will check the TOU settings according to the predefined rules (see below for “TOU setting format requirement” for details). TOU function will be disabled if the TOU calendar is set up incorrectly. If no errors are found in the calendar and the TOU function is enabled, TOU energy accumulation will begin.
TOU setting format requirement:
1. Season setting parameter: The calendar year will be divided up into different seasons depending on the season setting parameter. The parameter can be selected from any integer between 1 to 12. User must enter the correct value for the season setting parameter in accordance to the TOU season table. If the season setting parameter is set as 2, the first 2 slots of the TOU season table must be set, otherwise it will be considered as an invalid input (TOU function will be disabled).
2. TOU season format: Enter the start date into the TOU season table slot following this format “MM-DD ID” - MM stands for the month, DD stands for the day and ID stands for the TOU schedule ID (available from 01 to 14). The dates should be organized so that they are in sequence according to the calendar 88 year (the earlier date comes first and the later date comes last). For example, if 3 seasons are selected, the date parameters are January 1, June 6 and September 7, and TOU schedule 02, 01, 03 will be used respectively, the first TOU season table slot shall enter 01-01 02, the second slot shall enter 06-06 01, and the third slot shall enter 09-07 03. Entering 01-01 02 for the first slot, 09-07 03 for the second slot and 06-06 01 for the third slot is considered invalid.
3. Schedule setting parameter: The number of available TOU schedules depends on the schedule setting parameter. The parameter can be selected from any integer between 1 to 14. This parameter determines the number of TOU schedules available for the TOU calendar setting. A maximum of 14 TOU schedules (from TOU Schedule #1 to TOU Schedule #14) can be used.

Acuvim II Series Power Meter
V:1.0 Revised October 2018
86
4. Segment setting parameter: Each TOU schedule consists of various timing segments. The number of segments depends on the segment setting parameter setup. The parameter can be selected from any integer between 1 to 14 (inclusively). User must enter the correct value for the segment setting parameter in accordance to the TOU schedule table. If the segment setting parameter is set as 3, the first 3 slots of the TOU schedule table must be set, otherwise, it will be considered as an invalid input (TOU function will be disabled).
5. TOU schedule format: Each TOU schedule represents a 24 hour cycle. Similar to TOU season format, enter the start time into the TOU schedule table slot following this format “HH:MM ID” - HH stands for hour (in 24 hr format), MM stands for minutes and ID stands for tariffs (available from 00 to 03). The time should be organized according to the hour sequence. For example, if 3 segments are selected, timing parameters are 01:00, 15:30, 22:45, the order of the 3 segments should be one of the following: 01:00, 15:30, 22:45 or 15:30, 22:45, 01:00 or 22:45, 01:00, 15:30 Entering time information in a wrong sequence (for example, entering 15:30, 01:00, 22:45) is considered as an invalid 89 operation, TOU function will be disabled.
6. Tariff setting parameter: This parameter corresponds to the number of tariffs available for the TOU calendar and can be selected from any integer from 0 to 3. The four tariffs: sharp, peak, valley and normal are represented by 4 integers: 0, 1, 2 and 3 respectively. If the tariff setting parameter is set to 3, all of the 4 tariffs will be available for the TOU calendar; if the parameter is set to 1, only the first 2 tariffs (sharp and peak) will be available.
7. Holiday setting parameter: This parameter can be set from any integer between 1 and 30, meaning a maximum of 30 holidays can be programmed to the TOU calendar. If the holiday setting parameter is set as 3, the first 3 slots of the holiday schedule must be set, otherwise it will be considered as an invalid input (TOU function will be disabled).
Note: User can either customize the TOU calendar factory settings or use the default factory settings. User can reset the TOU calendar to its default value either via communication or from the meter front.
8. Holiday schedule: The holiday schedule uses the same format as the TOU seasons “MM­DD ID”. User can select which TOU schedule to be used for the holiday. The dates of the holiday schedule do not need to be organized in a sequential order (i.e. the first slot can be January 1, the second slot can be December 26 and the third slot can be December 25).
9. Daylight saving time (DST): Daylight saving time can be enabled in one of two formats: The fixed date option, or a fixed day of one of the weeks in the month (also named as the non-fixed date option). if you choose a fixed date option, you set the format according to a fixed date, for the daylight-saving time switch: the format month / day / hour / minute /
Find Quality Products Online at: sales@GlobalTestSupply.com

adjust time (in minutes). If you choose non-fixed date option, DST will be implemented by which day of which week, whose setting format is month/which day (i. e. Tuesday)/which week (i. e. 1st 90 week)/hour/minute/adjust time (in minutes).
By using the function, you can cause the instrument to automatically switch to and from daylight saving time. When the clock starts to run to daylight saving time, the meter will automatically adjust the clock to a time period in advance, while the clock is running to the end of daylight-saving time, meter will automatically adjust the clock pushed back to a time period, as shown in Fig 4-10
Fig 4-10 Daylight saving time setting interface
10. Ten-year Holiday setting
Users can preset holidays of the next decade via the meter software. The holiday format is month/day/year; holiday code; holiday schedule. After the format setup, click on "Make Holiday Settings (10 year)", then a holiday table for the next decade will be generated.
Holiday Auto Switch: When Ten-year Holiday is enabled, if the current year of the meter falls into the Ten-year Holiday setting, it automatically loads the Tenyear Holiday settings into the current TOU settings. If the current year of the meter does not fall into the Ten­year Holiday setting, it remains the current TOU settings.

Fig 4-11 ten years holiday table
11. Weekend Schedule: Weekend Setting (bit0: Sunday; bit1 ~ bit6: Monday to Saturday; bit 0 means not effective, bit 1 means effective). For example, when the Weekend Setting bit0 is 1, it means Sunday is effective. When the Weekend Setting bit1 is 1, it means Monday is effective. For example, if a user wants to set Saturday and Sunday effective, he should put 65 (1000001) into the Weekend 92 Setting field. When the meter clock is within the preset Weekend Schedule, the energy will accumulate under the tariff that corresponds to the Schedule.
Note: Holiday schedule has the highest priority among all the schedules. Weekend schedule's priority is followed by Holiday schedule. When Holiday schedule is not enabled, Weekend schedule has the highest priority, overiding the normal (weekday) schedule.
Acuvim IIE can record maximum power and current demand under different tariffs, as well as the time stamp of the maximum value. It can also clear the maximum demand under diferent tarifs.
Except normal energy parameter readings, Acuvim IIE has 4 separate logs: Current Accumulation Month TOU, Prior Accumulation Month TOU, Current Month TOU and Prior Month TOU. When setup appropriately and when TOU is enabled, energy will be

89
accumulated in a month-to-month basis. The current energy usage will be stored under Current Month TOU (or Current Accumulation Month TOU) and is divided up into different tariffs. When next month (or counting period) starts, all Current Month TOU values will be moved to Prior Month TOU (or Prior Accumulation Month TOU).
There are two ways of automatic resetting of current month TOU.
1. End of Month: This is the default method. All values from Current Accumulation Month TOU will be copied over to Prior Accumulate Month TOU at the very beginning of each month (the first day of each month at time 00:00:00). Current Accumulation Month TOU will continue to accumulate. All values from Current Month TOU will be copied over to Prior Month TOU at the very beginning of each month (the first day of each month at time 00:00:00) be cleared and reset to 0.
2. Assigned Clock: User can select when the values from Current Accumulation Month TOU or Current Month TOU would be copied over to Prior Accumulation 93 Month TOU or Prior Month TOU. User can set the time in the following format: DD HH:MM:SS"-DD stands for day, HH stands for hour, MM stands for minute, SS stands for second. Similar to the previous method, once Current Accumulation Month TOU is transferred to Prior Accumulation Month TOU, Current Accumulation Month TOU will continue to accumulate. once Current Month TOU is transferred to Prior Month TOU, Current Month TOU will be cleared and reset to 0.
4.7 Power Quality Event Logging and Waveform Capture
Power Quality Event Logging
When a power quality event happens, such as voltage sag and swell, Acuvim IIW will record the event timestamp and the triggering condition. It can save up to 50,000 events.
1. Event Logging Data format
Timestamp (4 words) + Triggering Condition (1 word) + Rated Value (1 word) + Threshold (1 word) + Half Cycle Count (1 word)
Each event has 8 words in total.

Bit1: 1 – u2 voltage sag, 0 – no u2 voltage sag; Bit2: 1 – u3 voltage sag, 0 – no u3 voltage sag; Bit3: 1 – u1 voltage swell, 0 –u1 no voltage swell; Bit4: 1 – u2 voltage swell, 0 –u2 no voltage swell; Bit5: 1 – u3 voltage swell, 0 –u3 no voltage swell; Rated Value: W6—Voltage rated value;
Threshold: W7—Threshold for voltage sag and swell.
Half Cycle count: W8 (Voltage Swell: 0; Voltage Sag: 4~200)
2. Logging Events
The event logging feature can log 50000 events. If the 50000 events are full, no more events will be logged even if the triggering condition happens. The user must clear the event log, and then the logging will log the new event. When the log is cleared, the new event will be logged from the first event happening. There will be no data loss after the power is of
3. Event Logging Triggering Conditions
1) Voltage Sag
When any phase of the three-phase voltage is lower than the set value (voltage rated value x threshold %), there will be a voltage sag event. When one phase voltage sag happens, the other phase will not respond to voltage sag event logging. Only when all of the phases voltage restore back to normal, a new voltage sag event will be responded.
2) Voltage Swell
When any phase of the three-phase voltage is higher than the set value (voltage rated value x threshold %), there will be an Voltage Swell event. When one phase Voltage Swell happens, the other phase will not respond to Voltage Swell event logging. Only when all of the phases voltage restore back to normal, a new Voltage Swell event will be responded.
Note:
The following figure depicts how to set the parameters for Power Quality Event Logging and Waveform Capture. In the parameter settings, Voltage Sag and Voltage Swell share the same voltage rated value. The parameters for event logging include: voltage rated value, voltage sag threshold, voltage sag half cycle count and voltage swell threshold. Those parameters also fit voltage sag 95 waveform capture. The other triggering conditions for Waveform Capture can be set when necessary. When the Waveform

Capture triggering by Voltage Sag and Voltage Swell is enabled, the corresponding event log and waveform will be recorded when Voltage Sag or Voltage Swell happens.
Fig. 4-12
4. Event Log Retrieve
When a new event log commences, the newest event number address (0X8CFDH) contains the newest event number. When the log is being retrieved, the starting event log number (0X8CFEH) and the event quantity for 96 each retrieve (0X8CFF) must be set correctly. It must be ensured that the starting number of event log should equal or smaller than the newest log number. When setup is correct, reading registers 0X8D00H—0X8D4FH will acquire the event log data. Each time a maximum of 10 logged events can be retrieved. The event log retrieve page is in the figure below. The Modbus register address of the event log is in the table below (see details in Chapter 6).

2. Waveform Capture Group
Waveform Capture can log up to 100 groups of waveform data. When the 100-group data is full, it does not respond to any waveform triggering condition. Only when all the waveform data is reset / emptied, waveform capturing function will be normal. When the waveform data is emptied, new waveform data starts from the 1st group. The waveform data will not be lost when the power is off.
Note: since the amount of each waveform group data is large, it takes more time to write into the flash memory. Therefore, Waveform Capture only responds to one triggering condition at one time. During the process of writing data into the flash memory, it does not respond to new triggering condition. After 99 the process of memory writing, it will respond to new waveform triggering condition.
3. Waveform Capture Triggering Condition
1) Manual Triggering
Manually trigger one group waveform capture.
2) DI Triggering
DI Triggering must fulfill the following two conditions at the same time.
IO modules with the logical address of 1 (AXM-IO11, AXM-IO21, AXM-IO31). DI channel type is set as “State”.
The Modbus address assigns two bits for the DI channel. When they are set as “00”, it means DI Triggering Disabled; “01” means DI Triggering will be implemented when DI state changes from OFF to ON; “10” means DI Triggering will be implemented when DI state changes from ON to OFF; “11 “means DI Triggering will be implemented when DI state has any change.
3) Voltage Sag Triggering
As mentioned in Voltage Sag event logging, when Voltage Sag Triggering Waveform is enabled, both event logging and waveform capture will be implemented at the same time once a voltage sag happens.
4) Voltage Swell Triggering

As mentioned in Voltage Swell event logging, when Voltage Swell Triggering Waveform is enabled, both event logging and waveform capture will be implemented at the same time once a voltage swell happens.
5) Over-current Triggering
When Over-current Triggering is enabled, if any phase of the three-phase current is higher than the set value (rated value x threshold %), the waveform 100 capture will be implemented. If one phase is over-current, any other phase overcurrent cannot implement the waveform capture. Only when all of the phase current restores back to normal, waveform capture will be responding.
4. Waveform Capture Retrieve
Because of large quantity of saved waveform, waveform retrieving window use 64 addresses to make retrieving data easier, which keeps consistent with recording points of one period. There are two retrieving methods, one retrieve waveform record reasons, another retrieve all data of one group waveform. Two methods are shown below.
First retrieving method is only retrieving waveform record reasons.
When 0x8E01H (Waveform Group Number) is set to 0, waveform record reason can be retrieved from data retrieving window, by changing Waveform Group Number for Retrieving (8E00H). Waveform record reason is 16 bytes and data window are 64 bytes, so that is the reason why each retrieving access include 4 group records.
For example, if the total number of Waveform Group Number for Retrieving is 19, the by this method, only through 5 times retrieving, all 20 groups waveform can be retrieved. Before retrieving, user should write 0 to 8E01H, and 1 to 8E00H, while at first time retrieving addresses from 8E00 to 8E43, these window data are the reasons of waveform group 1, 2, 3,
4. After retrieving, Waveform Group Number for Retrieving (8E00H) will automatically update to 5. While at second time retrieving addresses from 8E00 to 8E43, these window data are the reasons of waveform group 5, 6, 7, 8. Waveform Group Number for Retrieving (8E00H) will stop increasing after the value reaches 17.
Note: Unless user retrieves all data from 8E00H to 8E43H in one time, Waveform Group Number for Retrieving (8E00H) will automatically add 4, otherwise Waveform Group Number for Retrieving (8E00H) will keep present value if only 101 retrieving partial data. Waveform Group Number for Retrieving (8E00H) will stop increasing while value reaches Newest Waveform Group Number. If the value added 4, the value will be larger than Newest Waveform Group Number.

Second retrieving method is retrieving all waveforms data. When 0x8E01H (Waveform Group Number) is set to 1~121, each time only one group data of each number will be retrieved, then Waveform Group Number for Retrieving (8E01H) will automatically add 1 after retrieving. At next time, new Waveform Group Number will be retrieved. Waveform Group Number will stop increasing after value reach 121.
Note: The range of 0x8E01H is 0~121, within setting range, windows (8E04H~8E43H) are corresponding to waveform data.
0: Only retrieving waveform record reasons
1: Time and reasons of waveforms
2~11: Each waveform number of ten waveforms before U1 waveform is triggered
12~21: Each waveform number of ten waveforms before U2 waveform is triggered
22~31: Each waveform number of ten waveforms before U3 waveform is triggered
32~41: Each waveform number of ten waveforms before I1 waveform is triggered
42~51: Each waveform number of ten waveforms before I2 waveform is triggered
52~61: Each waveform number of ten waveforms before I3 waveform is triggered
62~71: Each waveform number of ten waveforms after U1 waveform is triggered
72~81: Each waveform number of ten waveforms after U2 waveform is triggered
82~91: Each waveform number of ten waveforms after U3 waveform is triggered
92~101: Each waveform number of ten waveforms after I1 waveform is triggered
102~111: Each waveform number of ten waveforms after I2 waveform is triggered
112~121: Each waveform number of ten waveforms after I3 waveform is triggered
Note: Unless user retrieves all data from 8E00H to 8E43H in one time, Waveform Group Number for Retrieving (8E01H) will automatically add 1, or Waveform Group Number for Retrieving (8E01H) will keep present value if only retrieving partial data.

5. Relationship between voltage or current waveform value and real value
The relationship between voltage waveform value and real value:
Real Value (Unit: V) = Waveform Value / 37.59105
The relationship between current waveform value and real value:
1) 5A,1A: Real Value (Unit: A) = Waveform Value/1683.153;
2) 333mV: Real Value (Unit: A) = Waveform Value/K (firmware above 3.21,K=14427.15; other: K = 15869.87);

4.8 Seal Function
The panel with seal, which has sealed key control, is different with one without seal. When the seal is in opened status, functions are same like normal meters. But when the seal is in sealed status, some functions of meters, which include parameters blocked by seal and optional parameters, will be blocked. These parameters can still be accessible by keys and communication way if they can be accessed before, but in sealed status, these parameters cannot be modified by keys or communication way anymore. Addresses about seal function are 101EH and 101FH.
Address 101EH is about parameters blocked by seal, which can be configured by users. These setting will be valid only when seal is in sealed status. Address 101FH is about if seal function is valid. When the panel is normal one, or the seal panel is in invalid sealed status, this address will show seal is open. When the seal is valid, this address will show sealed status and corresponding parameters will be blocked.
Parameters blocked by seal.
As long as seal is in sealed status, parameters below must be blocked, no matter what value of address 101EH.
