SELECT QC RUN
• QC RUN allows simple, automatic quality control run speed/ temperature verification when used
with the optional computer interface package. The QC RUN feature will run and document the
data from each set of parameters that has been saved in program memory.
• When QC RUN is selected, the SET DISPLAY will prompt you to prepare for the run and press
the START key to begin. The centrifuge will start running program number 1, and systematically
run each program in-order through program number 9.
• While the QC RUN is in progress, the parameters of the program that is running will be in the
SET DISPLAY.
• During a QC RUN the centrifuge checks if the preset speed and temperature can be reached. In
order to save time during the QC RUN the next program will be run once the desired speed has
been reached and the temperature is within
Note If you plan on using the QC RUN feature, consider the following as you save runs to
program memory:
• QC programs should all apply to using the same rotor.
• QC RUN programs should not use HOLD.
• To minimize the time it takes to perform a QC RUN, we recommend the following: Starting with
program 1, save runs to program memory. Sort first by temperature (highest first), then, if there is
more than one run at a single temperature, by speed (lowest first).
FOR EXAMPLE: The programs below are listed in correct order for using QC RUN (program
values shown are for example purposes only, actual set parameters will vary).

To select the QC RUN feature:
1. Press MENU key .
2. Input 1.
3. Install the correct rotor.
4. Press START key.
The QC RUN sequence will begin, running program number 1.
• If, during a QC RUN, the observed RUN temperature is more than 2°C over SET temperature,
the rotor continues spinning until set temperature is reached.
