Creating a Ménard pressuremeter probe
A Ménard pressuremeter probe can only be created or chosen from Volume loss test form, see Creating a volume loss calibration test.
Creating a new probe
(1) Select the volume loss test by clicking the right tab VOLUME LOSS.
(2) Click PROBE central panel. The list of existing probes is displayed.
Click Create new probe….
Selecting a standard probe
The list of Standard probes is displayed.
(1) Select the standard probe (ex. 44-RU-S-63).
(2) Click right probe panel to change the probe reference of the current volume loss test.
