TOF Measurement mode for time of flight
In this function you can select the mode of measure-
ment for the time of flight/distance within the gate. You
have two possibilities:
• Flank: You measure the time of flight up to the first
echo (at the first intersection point with the gate).
• Peak: You measure the time of flight up to the high-
est echo at the maximum amplitude.
If there is a distinct maximum amplitude, you should
always select the setting Peak, because in that case
the readings are independent of the set gain. You will
avoid node errors (e.g. half-wave jumps at the echo
flank). The measurement mode Peak is only possible if
the amplitude to be evaluated is < 110% screen height.
You must have selected the same TOF setting for the
calibration.
H Note:
With the setting Flank, the time of flight is derived from
the first echo and the amplitude is derived from the
highest echo within the gate.
Operation:
– Use I to highlight the left function group in the
right function table.
– Select the required setting Flank or Peak in TOF
using M.
