If two or more operators are present, both tasks can be performed at the same time.
The time it takes the tracer substance to reach the probes can be used to approximate the
flow velocity.
Attention: Start (F2) has to be clicked to start the measurement:
Only from this moment on the measured values are recorded!
During the measurement the course of the
measured values is displayed and refreshed
continuously. The (blinking) green dot in the sensor
window indicates a good connection. Especially at
the beginning and end of a measurement the
connection with the sensor must be good.
If instead of a green dot a red dot is blinking, there
is a problem with the connection. For further
information please refer to chapter 9.2.
If the connection is temporarily interrupted and then
reestablished during a measurement the missing
measurement values are read and transmitted from
a buffer in the sensor. If this happens the green dot
will be displayed for a few seconds until all buffered
values are received.
In addition, the percentage of successfully
transmitted measurement values is displayed. This
value should be 100% by the end of the
measurement. If this is not the case, please check if
all the relevant points were transmitted successfully.
Especially points on the rising slope and at or near
the maximum are important for a good
measurement quality.
Attention: Click Stop (F2) to finish the measurement. As soon as the complete tracer has
passed the probes and the measured values have dropped to the base value the
measurement can be stopped. The resulting curves and discharges will be displayed in a
