connected current sensors and shows their scale. If multi-scale sensors are connected, the user

must select manually the desired one. The analyzer shows one by default. The current ratios

can also be modified if the user is measuring at the secondary of a 5A transformer with 5

Ampere clamps, but wishes to view the values measured with respect to the primary of the

installation. Similarly, the ratio by default of the voltage transformer is 1/1. If this is not the case,

the primary and secondary voltages must be programmed for the voltage transformers.

The device recognises single-

scale current clamps and configures them

automatically. The AR6 only allows configuration of the current transformer’s ratio if

it detects multi-

scale clamps or 5 A primary clamps. For all other cases, it

automatically recognises the clamps and configures the current scale

10.2.2 Measurement configuration

Configuring a measurement involves the creation of a folder where all the configuration files and

data records will be saved.

Fig.10-5.- Measurement configuration screen (Example)

The configurable fields on the Measurement screen are:

Table 10-1.- Configurable fields on the measurement screen

Option Description

Name

Name of the measurement.

Description

Description of the measurement. Lets the user

indicate specific

data to facilitate locating or referencing the measurement.

Circuit type

Indicates the configuration of the measurement. The user can

select between:

• Single-phase

• Two-phases

• Three-phases, 3-wire

• ARON three-phase, 3-wire

• Three-phase, 4-wire

Nominal frequency

[50…60 Hz]

Nominal frequency of the network

where the measurement is

being taken. The user can select 50 or 60 Hz

Log period

[1…7,200 seconds

The log period for

the electrical parameters (in seconds). This

period is commonly used as averaging period for the variables.

Maximum demand

[minutes]

In this field the user

should program the energy integration

time to perform the Maximum Demand calculation.
