4.2.12 OUTPUT IMPEDANCE Menu [ iX Series only ]
Figure 4-25: OUTPUT IMPEDANCE menu
The iX Series offers programmable output impedance on selected models. This allows the user
to simulate line impedance conditions by programming resistive and inductive elements of the
AC source‟s output impedance.
Models on which this function is available are:
3001iX, 5001iX, 9003iX, 15003iX.
Note: On 9003iX-MODE and 15003iX-MODE systems, programmable impedance function
is only available in 3 phase mode of operation.
Alternative, one of the available OMNI lumped reference impedance options may be used to
increase the AC source output impedance for applications such as IEC 61000-3-3 Flicker testing.
The OUTPUT IMPEDANCE menu can be accessed from MENU 3. The following fields are
available in this menu:
Entry Description
RESISTIVE Sets the resistive component of the output impedance. This
value can be set from 17 m to 1000 m .
(The lower limits for the resistive and inductive components may
vary on different AC source models and are set as part of the
source calibration.)
INDUCTIVE Sets the inductive component of the output impedance. This
value can be set from 230 H to 1000 H.
(The lower limits for the resistive and inductive components may
vary on different AC source models and are set as part of the
source calibration.)
SET MINIMUM Selecting this field and pressing the ENTER key sets both
impedance components to their minimum values.
SET IEC1000-3-3 Selecting this field and pressing the ENTER key sets the output
impedance to the IEC 725 reference impedance values required
for IEC 1000-3-3 flicker testing.
