Signl This defines which signal should be watched for the transient event. Following
settings are possible: i, u, p.
Sync+Filt Here you reach a sub-menu in which you can setup some values:
Sync Selects the signal which is used for synchronisation. There are four
possible settings:
ChnU The voltage signal is used
ChnI The current signal is used
Line The line signal is used
Extn The signal at the external synchronisation jack is used.
Coupl Selects how the voltage or current signal is coupled to the following
trigger stage. This setting has no influence to the measured signals!
Please refer to 5.1.2, ‘Group A/B tab’.
Filt Here you can select if the filters in the signal path of voltage and current
are active or not. This filters are only in the signal way and don’t influence
the synchronisation. For the possible settings see 5.1.2, ‘Group A/B tab’
You have to leave this menu by pressing Enter or ESC. The settings for Coupl and
Sync you did in this menu are not used for the transient search itself but for
continuously measuring the TRMS and peak values of voltage and current. This
values are used to update the over and under range display in the status line.
