2.2 DESCRIPTION
The AR6 is a portable network analyzer for measuring grid parameters. It is the latest version of
the CIRCUTOR S.A. AR 4 and AR 5 portable analyzer series.
It is a digital measuring instrument that takes samples of voltage waves and current and
calculates RMS voltage and current values with a specific TMP averaged time. It includes a 1
GB internal memory for storing the data recorded at different installations.
The figure shows the instrument's control buttons and main screen.
Fig.2-1.- Main screen of the AR6
2.2.1 Active menu
The bar at the top shows the name of the screen being displayed.
2.2.2 Active measurement
It shows the name of the file where data are saved in the event this is required by the user.
2.2.3 Upper icons
These icons give analyzer’s status information. For more information see the chapter entitled
Upper bar icons
2.2.4 Configuration summary
The unit shows a measurement configuration summary window so that the correct configuration
of the analyzer can be verified. It displays the following information:

AR6 portable network analyzer
Page 10 of 71 User Manual
Fig.2-2.- Window showing the configuration
CORCO: Active measurement name
Three-phase 4 wires 50 Hz (DEFAULT TEXT). Description of the measurement (by
default the unit indicates the type of circuit selected when creating the measurement,
indicating DEFAULT TEXT). Users may change the measurement description text.
Voltage ratios 1/1 - 300: Transformers ratio for the voltage channel.
Current ratios: 100 -1/1 : 0- 1/1 : 0 – 1/1: Transformers ratio for the different current
channels. The three blocks correspond to the phase clamps, the neutral clamp and the
earth leakage current clamp.
Phase clamps; 100-1/1 means: 100 is the nominal current of the connected phase
clamp; 1/1 indicates that the unit recognises the clamp and auto-configures the scale.
The user must manually configure the scale only in the case of multi-scale clamps or
primary /5 clamps.
Neutral clamp; 0-1/1 : 0 means there is no neutral clamp. If used, this block would
indicate the parameters of the neutral clamp. 1/1 indicates that the unit is self-configured
Earth leakage current clamp; 0-1/1 :0 means there is no earth current leakage clamp.
If used, this block would indicate the parameters of the neutral clamp. 1/1 indicates that
the unit is self-configured
Recording period: 600 seconds: That is the configured log period.
Next trip: Condition (pending): This indicates if the recording needs a certain trigger
condition (parameter threshold or time gap). If it is not configured, the unit will display
"disabled"
2.2.5 Date and time
This displays the date and time at when the unit was configured.
2.2.6 Power button (On/Off)
To switch the analyzer ON or OFF, the user must press the ON/OFF button and confirm the
action on the menu that appears on the screen.
The button will light up either red or green in colour. The colour green indicates the unit is ON
and, if flashing, that it is in energy saving mode, with the screen off. Intermittent red indicates
that it is connected to the network and that the battery is charging, and the LED OFF means
that the analyzer is switched OFF.
2.2.7 REC/STOP Button (Log Control)
Once the user has configured and connected the unit, its correct connection must be verified by
checking the values displayed by the unit. If the connection is verified as correct, the user may
begin recording data by pressing this button. Likewise, in case that the user wishes to interrupt
an on going recording , this button must be pressed.
2.2.8 Validation (ENTER) button
This is used to run the function selected among the various options from the configuration and
display screens, or from the dynamic drop-down menu. It is referred to in this manual with the λ
sign.

2.2.9 Navigation keys
The unit has 4 navigation keys. These buttons have arrows drawn on them to indicate the
direction of cursor movement. In this manual these buttons are referred to with the ▲/▼, ◄/►
icons.
2.2.10 Buttons for drop-down menus
The analyzer function buttons are variable or "dynamic". The options displayed on dropping
down the menus for each of the function buttons are, different depending on the current screen.

2.3 CONNECTORS
Fig.2-3.- Connections on the top of the AR6
2.3.1 Voltage inputs
The voltage inputs of the AR6 are found on the top part of the unit, as shown in Fig.2-3. They
are identified with the symbols U1 (UA), U2 (UB), U3 (UC), UN(UN) and Uearth and identified
with different colours (identifier adhesive label may be chosen by the user).
2.3.2 Current inputs
The analyzer's current inputs are also found on the top of the analyzer, as shown in Fig.2-3.
This current inputs are identified with the symbols I1 (IA), I2 (IB), I3 (IC), IN(IN) and ILEAK. The
identification colours depend on the identifier adhesive chosen by the user.
2.3.3 USB port
This is a type B USB communications port, used for downloading recorded data. When the
analyzer is connected to a computer, the unit is recognized as an external drive, so it is not
necessary to communicate with the unit in order to download stored files, simply drag the files to
the desired directory of the computer or download them using the PowerVisionPlus® software.

module to extend the features of the standard analyzer, this is where expansion modules are
installed. The features of each one of the expansion modules are found in their respective
particular manuals.
2.3.5 Auxiliary power supply
This is the slot for the AR6 power supply connector. See the power supply features in chapter 4,
entitled TECHNICAL FEATURES.
3 INSTRUCTIONS FOR USE
The AR6 analyzer is a configurable measuring instrument that may be used in different ways,
which the user may select by means of different menu choices. It allows configuration of
different measuring methods, various recording times and log and trip conditions. Functions like
snapshots, averaging, rebooting maximum and minimum values display, wave shapes display,
rate of harmonic distortion, active and reactive power, both inductive and capacitive, energy
consumed and generated, among many other parameters can be displayed and/or recorded.
In order to ensure correct operation, carefully read the instructions given in this manual before
beginning measurements.

4.11 MEMORY
The internal memory must be handled with all possible precautions to prevent files
from being corrupted. Switch the instrument OFF to remove it.
The unit has an internal SD memory. It is not designed so that users must remove the memory
to read the data logged on it, as the data can be accessed and downloaded using a USB cable.
Users may change the unit's memory for one with greater capacity if necessary. It is very
important that the new memory card have the same folder structure as the one being
changed and be in FAT32 format.

4.11.1 Log capacity
The standard AR6 log for a 4-wire, three-phase system, saving all variables, occupies 4,230
bytes and the log header occupies 1,586 bytes (approx. 2 kb). Therefore, the log capacity can
be calculated using the following approximation:
N. of logs = (SD memory capacity in Mb * 1000 - No. files *2)/ 4.23
Log hours in 1 file = (SD memory capacity in Mb * 1000 - 2) * log period in seconds / (3,600 *
4.23)
4.11.2 Memory errors
It may occur that for reasons unrelated to the unit some memory partitions become inaccessible
or corrupt and the information stored in those memory sectors is lost. If the unit detects a write
access problem in log mode that prevents data from being logged to memory it will stop the log
automatically and warn the user that there is an access problem using the following alert. It will
also remove the SD memory detection icon from the upper menu.
Fig.4-2.- Memory access error
If the user accepts the warning but does not retrieve the card using the "Retrieve SD" tool in the
system's information menu and instead tries to log, the unit will show the following warning as a
reminder.
