5.2. Basic Measurements
Basic measurements consist of a single measurement without the need to reposition the transducers.
There are two basic measurements, depending on which parameter is known, either the path length
or the pulse velocity.

Saving Measurements
At the end of a
measurement the test
result can be saved.
Save into a file defined
by an ID number.
Do not save and return
to the previous screen.
Review List (Pundit Lab
+
only)
From the main menu, clicking on the system information key (See getting started) brings up a sub
menu:
Select this to key to display the system
information.
Select this key to go the review list which
allows previous measurements to be viewed.
An asterisk beside the pulse velocity or the
distance indicates that this is the parameter
that was calculated.
1st row : Measurement ( e.g. 4 of 16) / Time stamp
2nd row: Measurement ID / Temperature
3rd row: Frequency / Voltage / Gain / Correction factor / Rebound value (SONREB only)
4th row: Transmission time / Distance
5th row: Pulse velocity / Compressive strength / Conversion curve
5.3. Basic Measurement – Pulse Velocity
In order to measure the pulse velocity it is necessary to measure the path length between the
two transducers.
Select
“Basic Measurements”
Select parameter setting “path
length”
Enter the path length
Start the measurement
The display shows:
- Transmission time
- Measured pulse velocity
- Received signal level *
Stop the measurement
(Not necessary in burst mode)
Save the result or:
Adjust the gain settings.
(See Chapter 3) or:
Start a new measurement
* Best results are obtained when the received signal level is around 75%. Use the automatic
gain and voltage settings (See Chapter 3) for optimized performance.
