Settings tab
General
Language
Different languages can be selected form
this menu. After selecting a different
language, the software needs to be re-
started in order of this change to apply.
Line
frequency Frequency selection for the power network
where the actual component is measured
(not necessarily the AC input to IDAX).
Will set frequency for presentation in
Test tabs, for Line Frequency %DF/%PF
measurements and power frequency
interference measurements (in the
initialization procedure).
%DF/PF/TD Selection of %DF (percentage Dissipation
factor), %PF (percentage Power Factor) or
%TD (percentage Tan-delta = %DF).
Bushings Bushing terminals in Multiple Sweeps are
labeled according to ANSI (H1, H2…), IEC
(1u, 1V), ABC (A, B …) or Customized
labeling that is possible to edit.
Temperature Selection of Fahrenheit or Celsius for
ambient temperature entry.
Note
Object/insulation temperature is always
entered as degree Celsius.
Enable
keypad
Enables or disables the pop-up keypad
suitable for touch screen operation.
Enable
oscilloscope Enables the Oscilloscope (see upper right
corner in the main window)
Instrument configuration
Generator
The IDAX has two internal voltage
sources. One of maximum 200 V peak
(approximately 140 V RMS) output voltage.
The second source has maximum 10 Vpeak
(approximately 7 V RMS). By selecting
“External, VAX” and connecting the external
VAX 020 amplifier, the output voltage levels
can reach up to 2 kV peak
(approximately 1,4 kV RMS).
IDAX 322 has only two options: - 10 V peak
and 2 kV peak.
Test Leads The influence of capacitances and resistances
in the test leads is taken into account in IDAX
software. By defining the type of test leads
being used, the highest possible accuracy is
achieved. It is especially important for high
capacitive specimens and highfrequency
measurements. By pressing the “Edit” button,
a window appears where adding additional
test leads or changing values of existing test
leads is possible.
DFR (Frequency sweep)
Enable or disable the use of multi-frequency
generating/measuring technique for measurements
below 1 Hz. Multi-frequency mode generate and
measure three frequencies simultaneously, significantly
reducing the measurement time in the frequency
range < 1Hz.
Note Multi-frequency technique is preferred when
measuring to very low frequencies, typically
for moisture measurements in power trans-
formers. When measuring low capacitance
objects e.g. bushings or instrument transform-
ers, or in situations with very high interfer-
ence, standard single-frequency measure-
ments are recommended.
