Running time

In order to set continual running, the minutes, seconds and hours have to be set to zero.
Continual running is represented in the display by the following symbol, "".

Starting runtime timing

The start to runtime timing can only be set if the function, "Dual time mode" has been activated. See chapter
"Activate or deactivate function "Dual time mode". This function is activated ex works.

Press the key as often as is required until Timing begins at start or Timing begins at speed is displayed.
TIME

Use the knob to set Timing begins at start or Timing begins at speed.
Timing begins at Start = runtime timing begins immediately after the centrifugation run has been started.
Timing begins at Speed = runtime timing begins once the set speed has been reached.
If Timing begins at speed is set, this is shown in the display by the

Relative centrifugal force (RCF) and centrifuging radius (RAD)

Relative centrifugal force (RCF) depends on the centrifugal radius (RAD). Before RCF is set, the centrifugal
radius has to be set.

Press the key as often as is required until the parameters RAD and RCF are displayed and the value of
RCF
the parameter, RAD is displayed in parentheses,  e.g. RAD = 146

By changing the centrifuging radius, the value adjusts automatically to the RCF.
