FOR EXAMPLE :
The programs at right are listed in correct
order for using QC RUN; PROG # 5 (with
factory default settings) will be ignored
by the centrifuge when performing the
run (program values shown are for
example purposes only, actual set
parameters will vary).
Use specific options as follows:
SELECT QC RUN?
The QC RUN feature is considered usable only if the centrifuge
is equipped with the optional computer interface package. The
connected computer should have WatchLog Network™ soft-
ware running before starting a QC RUN.
When QC RUN is selected, the SET screen will prompt you to
prepare for the run and press START to begin. When START is
pressed, the centrifuge will start with program number 1, and
systematically step through each successive set of saved param-
eters until it has run every program saved to PROG # positions 1-
9 (programs will be skipped if they are programmed to factory
settings: SPEED=400 rpm, TIME=00:00, and TEMP=40). QC
RUN data will automatically be recorded by the WatchLog
Network™ software so that centrifuge performance with respect
to the SET speed and temperature is documented, and can be
verified.
NOTE If you plan on using the QC RUN feature, consider the
following as you save runs to program memory:
• QC RUN programs should not use HOLD.
• Programs with factory default settings of SPEED=400
rpm, TIME=00:00, and TEMP=40 will be ignored in
the QC RUN sequence.
• Although you may choose otherwise, to minimize the
time it takes to perform a QC RUN, we recommend
the following: Starting with program 1, save runs to
program memory in order – sorted first by temperature
(highest first), then, if there is more than one run at a
single temperature, by speed (lowest first).
ROTOR SPEED TIMED DEG C PROG #

To select the QC RUN feature, press MENU, input 1, install
the correct rotor, make sure WatchLog Network™ is running
on the connected computer, and press START. The QC RUN
sequence will begin, running program number 1, and the run
status will be displayed on the WatchLog Network™ com-
puter screen.
