lift up the D-rings until they snap into a vertical position, then use them to rotate the
fastener posts until released (refer to the figure below).
5. While grasping the D-rings, carefully pull upward to loosen the preamplifier connection
under the mounting plate, than raise the assembly (mounting bar with probe and
preamplifier attached) out of the magnet gap.

Intelligent probes were developed for the minispec mq-Series. When you exchange a probe,
the software will read the most important parameters (pulse length, resonance frequency)
from the probe itself. The software will prompt the user to confirm the settings. After
temperature stabilization it is recommended to run the Daily Check procedure. In certain
cases a fine tuning by running Update Settings may be beneficial.
