4. Ext. [In A] & Ext. [In B]
In this option only values via external accessories are being measured regardless of generated
power. User cannot change generated parameters; all changes are possible only when item no.
1 is selected in this menu. However, Generator can be in running state if it was started
previously.
In this option only this screen is shown to the user from all generator’s screens (green ones).
When this option is pressed main blue screen appears with regards of used accessory.
5. Phantom Load
This is a unique option in this menu. Principally Phantom
Load enables to generate current into existing load
(voltage remains intact). That’s why only current related
parameters can be changed in this screen.
This screen can be opened only if voltage measuring
accessory is connected into input B of the device,
otherwise error message appears!
In the top user can set amplitudes and phase shifts for all
phases of current. Phase shift is related to the voltage
which is being measured by the accessory. Measured
voltage and its phase shifts are visible in the bottom part
of this screen. They are read only as well as the frequency
in the middle.
User can also change the connection type 3P4W, 1P2W,
etc. and the shape of signal (see chapter 4.1 on page 21).
