WARNING
Danger of injury due to falling lid
The hinged lids may close unexpectedly during probe exchange causing injury to hands or
fingers.
u Ensure that the gas spring on the outer lid is operating correctly.
u The blue inner hinged lid does not have a gas spring, use extreme care when
exchanging the probe assembly.
4. The probe assembly is fixed with two quick-release fasteners. To release the fasteners,
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.
