Description
Hardware initialization
During hardware initialization, the system returns all motorized parts (i.e., the
gantry, HSM module, and thermal cycler) back to their home positions.
Additionally, the system checks for the presence of any tips on the
micropipettor and, if necessary, disposes of those tips in the tip waste bin.
Instrument Health Check
(IHC)
The system performs an IHC each time it is powered on (after login) and each
time a protocol run is initiated. The checks performed during the IHC ensure
that the hardware is functioning within specifications.
Teach-point verification
Auto-teaching is a process in which
the system locates and records the
positions of markers (called teach points) that are printed on the instrument
deck.
Auto-teaching
ensures that, during a run, the micropipettor is accurately
aligned with the tubes or wells at each deck position.
You can configure the system settings to include teach-point verification as
part of the initial IHC that is performed after powering up the instrument (see
“Running Auto-Teaching and Teach-Point Verification”
teach-point verification, the current teach-point locations are compared to
those that were previously recorded during the most recent auto-teaching run
to ensure that the values are sufficiently within range of each other. If the
values do not fall within the expected range, the system prompts you to rerun
auto-teaching.
