2.4 Radius Correction

If adapters or reducers are being used, it could change the centrifugal radius of the respective rotor.
In that case, the radius can be corrected manually.
Please proceed as follows:
First close the centrifuge lid and press afterwards the key "time" (6) and the key "prog" (11) at the
same time and hold down.
In the display, "time" (A-3), appears the word "radius" (M9). With the adjustable knob (1), pre-select
the respective radius correction, (see Table 6, APPENDIX P. IX), in steps of 0.1cm.
As soon as the radius correction is set, the word "radius" (M9) appears. This text remains visible
until the radius correction is set back to 0.
For all number marked text, please refer to Figure 20.

2.5.1 Storage of Programs

The program stores up to 99 runs, with all relevant parameters, including the used rotors. Any free
program number is available and can be retrieved.
Put the desired rotor into the centrifuge. By pressing the key, "prog" (11), in the display "time" (A-3)
appears the word "program", (see Figure 21). With the adjustable knob (1), choose the desired
program number.
If a program number is already occupied, in the display "rpm/rcf" (A-1), the words "rotor" (M3) and
"22x.xx" (M4) will appear, (see Figure 21). Free program numbers will appear as 0.
