Trigger Parameters for Line Fault Recording
An overview (flow chart) of the complete trigger menu can
be found on page 54.
Mains Failure Measuring Range:
MAinS rAnGE
A measuring range of either 300 V or 600 V can be entered
here for line fault recording.

Trigger Thresholds
H-triG
and
L-triG
Measuring function V for line fault recording requires its
own upper and lower thresholds for triggering purposes.
The upper limit should always be greater than the respec-
tive lower limit.
Entering upper and lower thresholds in digits:

rAnGE: XXXX V

e.g.
600 V

e.g. 250000 = 250.00 V
L-triG: XXXXXX

e.g. 190000 = 190.00 V
Examples for the entry of trigger thresholds in digits can be
found in the table in Chapter 17.1, page 32.
Drop Out Trigger Level:
triG drPout
A level with a value ranging from 0 V and 600 V can be
selected here in 10 V steps for the mean value of the volt-
age measurement for the respective time period.
