Step-Mode Operation - Thermo Scientific Sorvall RC6 Plus Instruction Manual

Step-mode Operation

This centrifuge has the step-mode operation capability that allows you to save three different sets of
values for a run parameter set in a single memory location (MEMORY Nos. 31 - 33, 41 - 43, and 51 -
53) and then change some or all of the run conditions (e.g., speed, run time, rotor temperature, etc.)
for each step during a step-mode run. Save step-mode run conditions at the MEMORY Nos. 31 - 33
(41 - 43 or 51- 53) in accordance with "3-3-1 Programmed Operation (1)".
When the MEMORY No. 31 is recalled, the centrifuge automatically performs step-mode operation in
order of MEMORY Nos. 31, 32 and 33.
Procedure for step-mode operation
Example
The table below shows the run parameters and their values required for an example 3-step run
(MEMORY Nos. 31 to 33). Fig. 4-6 depicts how the example run will proceed.

Note
1. Select the same rotor number for each step. Otherwise, alarm message "ROTOR NO." is
indicated and the centrifuge stops operation. (Contents of the memory cannot be called up.)
2. Use the MEMORY Nos. 32 and 33 (42 and 43 or 52 and 53) for the step-mode operation with
two steps.
