Normal Operation
Read the Safety Information Page at the front of this manual.
1 Check all OPTION LED indicators – if selection changes are
required, press MENU, then press ENTER to access each option
screen in succession (see figure 4-1). As you step through each
screen, you may select or deselect, and change or accept the
previous setting. To check an existing selection setting (Slow
Start/Stop rates, Brake Off speed, Overtemperature Limit point
or Step Run sequence), press 1 to display the option's secondary
screen, then view the displayed value. When finished with all
changes, press MENU to return to the HOME screen.
2. Prepare the rotor according to the rotor manual instructions,
then open the chamber door and install the rotor, making sure
that the rotor is fully seated and locked to the drive spindle.
Install the rotor cover, if any, then close the chamber door. Make
sure that the SET rotor matches the installed rotor. If not, press
ROTOR repeatedly until the name of the installed rotor appears.
3. Check the settings in all other fields in the SET display – input
changes to specific parameters as follows:
a. If you require a change to the SPEED (rpm) or RCF ( g force)
field, press SPEED and input the desired value. Values in
excess of the maximum for the specified rotor will not be
accepted (the value will continue to blink). To change mode
from rpm to RCF, or from RCF to rpm, press SPEED more
than once; an equivalent value will be calculated (based on
the maximum radius of the specified rotor) and displayed.
b. If you require a change to the TIMED/HOLD/ACE field,
press TIME, HOLD, or ACE to select a run duration control
method and, if you did not select HOLD, input a desired
termination value (in minutes and seconds up to 99:59, or in
ACE up to 9.99e30 [9.99 x 10
30
]). Always be sure of the control
method and value before starting the run.
c. If you require a change to the DEG C field, press TEMP and
input the desired sample temperature between –10 and 40
°
C.
Read the sections regarding Temperature Control and Rotor
Temperature Equilibration found on page 4-11.
4. If using WatchLog Network™ run logging software, make sure
it is running, then press START (START indicator will blink,
then stay lit once the rotor starts to spin).
The rotor will accelerate to the set run parameters, and continue
until run termination. At termination, the STOP indicator will light
and the rotor will decelerate to a stop. After it stops, START and
STOP indicators will turn OFF, and "End" will appear in the SPEED
display and remain there until the door is opened.
