27 SplitMode
logger file splitting mode:
0
– no splitting
-1
– split after each measurement cycle
15
– split after each full 15 minutes of real time clock
30
– split after each full 30 minutes of real time clock
60
– split after each full hour of the real time
1440
– split at defined times
28..33 SplitTimeN
Six timestamp values of logger file splitting (only if SplitMode is
1440):
-1
– value is inactive
0..1439
– time in minutes (for example, 100 means 1:40 AM)
34 GpsLast30sSyncTime
time in seconds between start of measurement and last
synchronization of real time clock based on GPS signal:
- Value 0FFFFh means that within 30 seconds before the
start of measurement, real-time clock synchronization did
not occur
-
The parameter says nothing about synchronizing the
real-time clock before 30 seconds prior to the
measurement start
35..36 MeasureStartTimeMs
measurement start time in milliseconds
37 SplitCycles
number of split measurement files (zero means infinity) - the
parameter is important if the duration of the measurement cycle
(IntTimeSec) is set to infinity; for finite measuring cycle times this
parameter is irrelevant (see: RepCycle)

-
Other remaining values
3 TriggerLevel
trigger threshold value in 0.01 dB format (parameter relevant only to
modes in which triggering is related to signal level)

to „Grad+” mode)
