1.- DESCRIPTION
This manual is aimed to familiarize de user with the operation of the “Flicker
analyzer” program for the portable analyzer model AR5.
To get all necessary information about operation instructions and safety warnings of the portable analyzer AR5 consult its instruction manual (code M981504).
According to the user’s choice, the analyzer stores in memory files with following extensions: *.A5F and/or, *.A5M “Standard” or *.A5T “Especial”.
Recording data process is done by means of a liner memory. That means that once memory is full, no new data is recorded anymore.
2.- Checking the contents of your package
After receiving the analyzer, please check the following points:
a) The delivered material corresponds with your order specifications. b) After unpacking, check that the instrument has not been damaged in transit. c) The standard set includes the following items:
• 1 cartridge for programming the AR5 containing the ordered operation
mode program.
• 1 Instruction Manual.
• 3,5” diskettes containing the PC software update.

3.- ANALYZER STARTUP
3.1.- Loading a new program
The AR5 has an internal memory to save diverse operation mode programs to be used by the user.
Before initiating this procedure, check than the AR5 battery is charged. Loading program action cannot be done whether the power supplier set is connected to the AR5, since the cartridge is to be connected to the input also used to connect the power supplier set.
To load any program, follow these instruction precisely:
•
Turn the meter off.
•
Connect the cartridge to the AUX input of the meter.
•
Turn the meter on.
•
Select with the keys [5] & [6] that you want to perform a program loading action
(LOAD PROGRAM). Press [ENTER] or wait for a while to confirm this operation.
•
Select the position to save the program into.
•
The AR5 will perform a test to check that the cartridge has been properly
connected.
•
If an inserted cartridge is detected, then the program will be loaded.
•
Once the loading is completed, reset the meter.
•
If no cartridge was found or a loading mistake occurred, reset the meter and redo
the above steps.
A cartridge will be only valid for the analyzer which the
program was for the first time loaded into.
Note on the cartridge the serial number of its related AR5.
Page 5
3.2.- Choice of the operation mode program
The AR5 can hold in memory different operation mode programs. The choice of the program to be used is done when starting the meter up.
• Turn the AR5 on.
• A list of available programs will be shown on display.
• Use keys [5] & [6] for the choice of the desired program.
• Press [ENTER] or wait for a while to confirm this operation.
CHECK THE SETUP UP !!!!
5
All programs have an independent setup, therefore, the setup must be always check to ensure a proper operation.
For instance, whether the setup is modified at the “ANALYZER” program, these modification will not be valid for the “FLICKER” program, and so for any program.
3.3.- Energy saving
The AR5 analyzer is equipped with a saving energy system in order to enlarge its operation autonomy. That way, if no key is pressed for at least 5 minutes, the display is automatically off. The analyzer continues the recording data process but nothing appears on display.
The display will be automatically on when any key1 is pressed.

Some warning messages can appear at the visualization screens. These
messages inform about the AR5 performance:
- STOP: The analyzer is not recording data.
- TRIG?: Trigger conditions are not met. No data is being recorded.
- M. Full: Memory is full.
- M.Error: There is an error in the memory. The memory must be formatted.
- Analyzer’s battery status. Notice than when only one bar is shown, the analyzer’s battery is very low and this can be powered off at any moment.
- WARNING MAX 500 V: The maximum allowable phase to neutral voltage of 500 V has been exceeded during the measuring process. When measuring phase to phase voltages the limit is set at 866 V.
Page 13
5.- PROGRAMMING THE AR5
To accessing AR5 setup options press the key [SET]. The analyzer will then inquiry for a password that consists of a key sequence to be pressed (the user has 15 seconds to press this sequence):
13
PASSWORD [3] [SET] [5] [SET]
Once this password is entered, the analyzer will permit the user to modify any
Setup parameters.
All programs have an independent setup, therefore, the setup must be always check to ensure a proper operation, since any modification will only affect the active operation program.
Diverse setting MENUS are available:
SETUP DISPLAY RUN FILES CLEAR
• Select one option with keys [6] & [5].
• To access any menu option use [4] or [ENTER].
• To close the menu press [3] or [ESC]. If this key is used when only the
main menu is open, this is closed. Whether any modification over any setup parameter was done, before closing a confirmation of setup change is requested on display.

- REL. V: Voltage transformer ratio. The primary voltage is firstly asked, and then the secondary voltage.
- REL. I: Ammeter clamp primary.
NOTE 1 : If voltage is directly measured (no voltage transformer is used), you must set PRIM.V = 1/SECV.V = 1. NOTE 2 : REL. I --> This option permits to program:
a) The ratio of the ammeter clamp to be used. b) In case of a high voltage system, the measurement will be carried out through
the secondary of current transformers. A shunt ATS-III 5 A a.c./ 2 V a.c. or CP-5 clamp will be then required to enter the measurement signal into the AR5 analyzer (Never directly connect the 5 A signal to the AR5.). For this case, the C.T. primary must be set at the primary value of the C.T. used for measuring purposes.
Ratio set must be modified for each ammeter or transformer type change to avoid measurement mistakes. Standard clamps give a voltage output (generally 2 a.c. at full-scale).

5.1.2.1.- PERIOD: recording period
All values measured by the AR5 can be periodically saved in memory. The
recording period (time period between each record) is user-definable.
Each record consists of the average values measured during the pre-defined period. This recording period can be from 5 s to 4 h for the standard and special type files (files .A5M & .A5T).
5.1.2.2.- TRIGGER: Trigger conditions
TRIGGER
LEVEL TIME
You can program here certain conditions (Trigger) so that values are saved in memory only when these conditions are met.
Two types of trigger conditions are available:
1) Time trigger (TIME): DATE/TIME of ON (starting measurement process), &/or OFF (ending measurement process).
2) Parameter trigger (LEVEL): you can set a maximum threshold (measured values must be higher) &/or a minimum (measured values must be lower) that define the value range within the recording actions are performed (thus, for instance, the voltage to be higher than a certain level, or the current lower than another one, etc.).
Whether the defined trigger conditions are met, the AR5 stores data to its internal memory (STORE ON); and, on the contrary, no information is stored to memory (STORE OFF) and the display will show the message TRIG?.
Page 17
• LEVEL:
Lets to set the trigger for a parameter, as well as its maximum and minimum
range-limiting values.
- PARAM:
Choice of the parameter for the trigger condition: (rotary input).
- Select with keys [6] or [5] the desired parameter: Vp-p, Vp-n, A, kW, kvarL, kvarC, PF, Hz, kVA, Auto (None).
- [ENTER] to validate the choice. ([ESC] to exit with no modification)
- MAX:
Set here the maximum threshold: (numeric input).
- Select with keys [6], [5], [4] or [3] the desired value and press [SET] to validate each figure. Select “Í“ on display + [SET] to delete a figure.
- [ENTER] to validate the total value or [ESC] to exit with no modification.
- MIN:
Set here the minimum threshold: (numeric input).
- Select with keys [6], [5], [4] or [3] the desired value and press [SET] to validate each figure.
- Select “Í“ on display + [SET] to delete a figure.
- [ENTER] to validate the total value or [ESC] to exit with no modification.
17
Note: the set value will be valid only if a trigger parameter was previously defined.
POINTS TO CONSIDER:
If the selected parameter is voltage, current or any power:
1) When setting the maximum and minimum values take into account the units:
Parameter Format Voltage V. With decimals kV
ex. 230.V 230.0kV Current A Power kW
If the frequency is selected, both the maximum and minimum values can be typed with a decimal (xx.x).
2) The trigger condition is met when either the instantaneous value of any of the three phases (L1, L2 or L3) or the three phase value of the selected parameter is higher than the maximum or lower than the minimum (the analyzer switch from STORE OFF to STORE ON).
Minimum Maximum
STORE ON <------ ......STORE OFF...... -----> STORE ON
any any
lower value higher value
• TIME:
Page 18
Lets to set the time trigger, that is, to define the period to perform the data
storage.
- TIME ON:
When selecting this option the present ON conditions are shown on display:
TIME .ON 00 /00 /00 00 :00 : 00
day/month/year hour:minute:second
- Pressing [ENTER]: ON values on display are directly validated.
- To modify: (rotary input).
- Select with keys [4] or [3] the position to modify.
- Though keys [6], [5] the value of the selected position is increased or
decreased.
- [ENTER] to validate the total value or [ESC] to exit with no modification.
- TIME OFF:
When selecting this option the present OFF conditions are shown on display; and
the procedure is equal to the above one.
18
TIME .OFF 00 /00 /00 00 :00 : 00
day/month/year hour:minute:second
POINTS TO CONSIDER:
a) To void the time TRIGGER, all values must be zero.
b) If only the ON & OFF TIME are programmed (two DATES set to zero), the defined time period will be cyclically repeated by the AR5.
ADDITIONAL NOTES:
a) The AR5 will save data in memory only when both TRIGGER conditions are met:
Time (ON-OFF) and Parameter (maximum and minimum). If any condition is not met, no value is stored to memory (STORE OFF state). In case that trigger conditions are void (ON & OFF set to zero, and parameter set to AUTO), all values will be saved in memory according to the previously defined recording period.
b) If trigger conditions are met at any moment within the defined recording period, the
average values for the whole period will be saved in memory.

If the typed name and extension already exists in memory, when exiting
setting actions, the display will show:
“Overwrite file Sure? “ --> Do you really overwrite the file?
If yes is answered, the previous file is deleted.
If no is answered, setup menu is not exited, thus a new name can be typed for
the file, or the setting actions can be cancelled.
POINTS TO CONSIDER:
Whether the name of the working file is change, previous file will not be deleted, since several files can be at the same time saved in the AR5 internal memory provided these are differently named. All data will be automatically saved in this file until a new one is opened.
5.1.2.4.- TYPE: recording file type.
Select here the file type wanted for the data recording actions of the AR5. With keys [6] or [5] choose the file type: Standard or Custom and/or Flicker:
These are distinguished in memory with its extension:
- A5M Standard file (preset parameters).
- A5T Custom file (user-selected parameters).
- A5F Flicker file (preset parameters).
Length of data saving records is different as per each file type. Memory autonomy for a 15 min recording period is listed below:

5.1.2.5.- PARAM: Choosing the parameters to be saved
As said before, parameters to be saved in memory are user-definable when working with Custom type files (extension .A5T - see section 5.1.2.4.-).
Note: This option does not vary the stored parameter if the selected file is a Standard type one (extension .A5M) or a Flicker type one (extension .A5F), but would modify the parameters to be stored whether a Custom type file (extension .A5T) had been selected.
¾ Pressing [ENTER] previously user-defined parameters are automatically
validated.
- To modify:
¾ Place over the desired parameter with keys [6], [5], [4] or [3].
¾ Pressing [SET] the state of the parameter switches. Parameters to be
saved are on a black background, and the ones to be not save are on a white background.
¾ Placing over the text Inst (Instantaneous values) and pressing [SET], you
can now select the maximum values to be saved (MAX).
¾ Placing over the text Max (Maximum values) and pressing [SET], you can
now select the minimum values to be saved (MIN).
¾ Press [ENTER] to validate the choice or [ESC] to exit with no modification.
___________________________________________________
Note: If values are being saved in a file A5T and the parameters to be stored are changed, when exiting setting actions, the display will show:
