With the Centrifuge 5702 R / 5702 RH it is possible to store up to two permanent programs (only during standstill):
First set the required program data with the TIME and SPEED dial adjustors. The function "at set rpm" and the switched-
off braking function can also be stored if necessary in the permanent program.
Program selection is only possible during stillstand
.
If dial adjustors or buttons are required for the program setting, the program remains unchanged.
The text "Pr 1" (Program 1) or "Pr 2" (Program 2) appears in the centrifuge display.
Exit the program by again pressing the program button. The blue lighting of the button extinguishes and the centrifugation
parameters can be set freely again.
If the centrifuge is not used for more than 8 hours or the lid is not opened, the refrigeration switches off to protect the
device.
Remark: In cases of higher ambient temperature, temporary air noises may occur until the desired temperature is
attained. These are a sign of high refrigeration capacity. Block the ventilation slots under no circumstances!
For ambient temperatures below 18 °C a warming-up time of 1 hour is required before operating.
PROG 1 or 2
–
Hold down for 2 seconds until the program button is no longer flashing and lights up
continuously. A brief signal will sound. The program is now stored.
PROG 1 or 2
–
Pressing once calls up the required program. The button for the program activated
lights up in blue.
temp
–
The nominal temperature value can be set with the arrow keys from
– 9 °C to + 40 °C. During stillstand, the nominal temperature setting and the current
temperature in the rotor chamber are displayed alternately. With the centrifuge
running, only the current temperature in the rotor chamber is displayed.
A deviation of more than ± 3 °C from the temperature set is signalled during the run.
fast temp
–
starts a controlled temperature run with a centrifuge-specific rotation speed, in
order to quickly reach the selected temperature in the rotor. During the FAST TEMP
run, "FA" appears in the display, as well as the present temperature and the fixed
optimal rotational speed. The run ends automatically or by pressing the STOP
button. A signal tone sounds periodically.
Stand-by refrige-
ration
–
With closed centrifuge lid the rotor chamber is refrigerated before and after a run to
the selected nominal temperature if this is less than the ambient temperature. Since
there is no rotation of the rotor, the temperature adaptation takes place slowly. If the
centrifuge was in standby refrigeration over a longer time or at low temperatures,
start a brief FAST TEMP run before inserting the samples in order to prevent the
samples from freezing.
