Scale Factor
Factory setting: Scale factor = 1.
The parameter Scale factor (SF) multiplies a calculated distance value with a factor that can be selected
within the range from –10.00000 to +10.00000 to allow changes in resolution setting or output of results in a
unit of measure other than the metric system.
Up to five positions after decimal point can be processed.
To make settings for Profibus system operation, SF needs to be multiplied with 100.000. The resulting num-
ber must then be converted into a 32-bit hexadecimal number. In Profibus setup mode, a mathematically
obtained number can be entered at bytes (Octet) 55 ... 58 of the table of parameter setup data.

8.2.4
Trigger Mode
The parameter Trigger Mode enables (1) or disables (0) external triggering.
Factory setting: Trigger mode = 0.
8.2.5
Trigger Level
The parameter Trigger Level defines if measurement will start on a rising (0) or a falling (1) pulse edge.
Factory setting: Trigger level = 0.
8.2.6
Trigger Delay
The parameter Trigger Delay sets the time from the arrival of a trigger pulse to the actual beginning of mea-
surement. It may correspond to any value between 0 and 9999 msec.
Factory setting: Trigger delay = 0.
