8.1. BASIC SETTING: ANALYZER CONFIG
Place the rotary switch in the ANALYZER position, press the MENU key, using the F1/F2
keys select the ANALYZER CONFIG item and press the ENTER Key.
The following page will be displayed:

This page of setting can be confirmed by pressing the
ENTER key or cancelled by
pressing the
ESC key.
8.1.1. Type of electrical system under test
The parameter SYSTEM is fixed to "SINGLE" value as the instrument is able only to
analyse Single Phase system.
8.1.2. How to set the fundamental frequency
Position the cursor on the corresponding word by pressing the multifunction keys
F1 and
F2 and select the network frequency between the possible values 50Hz and 60Hz by
pressing the multifunction keys
F3 and F4. This parameter is important ONLY if the input
voltage is not sufficient to recognise the value of the frequency (for example, only the
clamps for the current measurement are connected). In this case the instrument generates
an internal synchronism equal to the value of the set frequency.
8.1.3. How to set the current range
The value of this parameter
must be always equal to the full scale of the current
clamp used to take the measurement. In case multi-scale clamp is used, the value of this
parameter must be equal to the scale selected on the clamp.
Set the desired value by pressing the multifunction keys
F3 and F4.
8.1.4. Clamp Type
The value of this parameter
must be always equal to the clamp type you are using.
Three types of clamps are available, set the desired value by pressing the keys
F3 and F4:
STD: for Standard clamps or Current Transformer
FlexEXT: for Flexible clamps with External electronic control box
FlexINT: for Flexible clamps without any electronic control box
CAUTION
If “FlexINT” is chosen the current range could be set only to 1000A or
3000A.
