1. A method comprising:
positioning a downhole tool including a probe tool at a location within a wellbore;
initiating testing using the probe tool including starting an extension timer and actuating the probe tool to extend a probe mechanism to engage a wall of the wellbore by applying an actuation fluid pressure at a known fluid flow rate and a known pressure to a moveable portion of the probe tool; and
determining that the probe mechanism has made contact with the wall of the wellbore by monitoring a pressure level of the actuation fluid pressure and determining that the actuation fluid pressure exceeded a threshold pressure level within a time limit set by the extension timer.
