2. Use the [Rotary knob] to select the desired setting.
■ ‘Timing begins at Start’ = Runtime counting begins after the start
of the centrifugation run.
■
‘Timing begins at Speed’ = Timing of the runtime starts after the
set speed is reached.
This is indicated by the ‘é’ symbol in the indicator to the left of the
time.
3. Press the [TIME] button.

7.1.3 Speed, RPM
1. Press the [RPM] button.
🡆 The ‘RPM’ parameter is displayed.
2. Use the [Rotary knob] to set the desired value.
3. Press the [RPM] button or the [START] button.
🡆 The setting is transferred to the indicator.
7.1.4
Integral RCF
Integral RCF is a measure of sedimentation effect (∫ n2 dt). The value is
used to compare centrifugation runs.
The integral RCF is not saved. The integral RCF is deleted
after starting the next centrifugation run or switching off the
device.
If the ‘Timing begins at Speed’ function is selected, calcula-
tion of the integral RCF only starts after the set speed has
been reached.
■
Integral RCF is enabled.
1. Press the [RCF] button repeatedly until the integral RCF is displayed.
2. Press the [RCF] button.
🡆 The centrifugation data is displayed.
3. If necessary, press the [RPM] button.
🡆 The RPM is displayed.
1. Press and hold the [PROG] button.
🡆 ‘***Machine Menu***’ is displayed after 8 seconds.
2. Press the [PROG] button repeatedly until ‘-> Settings’ is displayed.
3. Press the [START] button.
🡆 ‘SOUND / BELL = on’ or ‘SOUND / BELL = off’ is displayed.
4. Press the [PROG] button repeatedly until ‘RCF Integral = on’ or ‘RCF
Integral = off’ is displayed.
5. Use [Rotary knob] to set ‘off’ or ‘on’ .
off = integral RCF disabled
on = integral RCF enabled.
