Start-up and run-down parameters

The set start-up and run-down parameters are displayed.
x: 1-9 = start-up stage, t = start-up time

Start-up stage and start-up time

It is only possible to set start-up times if these have been activated. See the chapter "Activating or deactivating
start-up and run-down times".

Press the key until the parameter
= start-up stage, t = start-up time
Press the key to switch between the start-up stage and start-up time.

15.5.2

Braking stage and run-down time

No B-brake stages can be set for this device. The activation of the B-brake stages in the "Settings" menu is
not possible (parameter B-Ramp = off). B-brake stages are similar to an exponential braking curve.
It is only possible to set run-down times if these have been activated. See the chapter "Activating or
deactivating start-up and run-down times".

Press the key until the parameter
= braking stage = B- braking stage,
Press the key to switch between the braking stage and run-down time.

Temperature (only for centrifuge with refrigeration)

The temperature can be entered in degrees Celsius (°C) or in degrees Fahrenheit (°F). For setting the
temperature unit, see chapter "Set temperature unit".
If degrees Fahrenheit (°F) is set as the unit of temperature, the letter "F" appears after the temperature value
on the display.

Press the key. The following parameters are displayed: T/°C or T/°F.
