Input in the time field
1. Running time
The running time can be pre-set for a particular timeframe or unlimited (hld =
hold). After a set time has elapsed, centrifuging stops automatically.
Time pre-setting in h.min mode:
- in hour, 10 minute or minute blocks up to 9.59 (9h 59 min).
The h-mode can be used for longer running times:
- ten hours or hour blocks from 10h to 99h.
Attention!
Running time is calculated from the start until the moment of deceleration, i.e.
deceleration time is not included in the running time.
2. Start delay
The start time point can be pre-planned up to 99 hours. It is entered and
managed as described for the running time (see above).
With the start delay set, the timer is activated only after pressing the start
key. In the four-function field, "delay" is also shown for the duration of the
start delay. If no start delay is necessary, the setting "---" is displayed.
Input in the temperature field
1. Sample temperature
The set value of the sample temperature can be set in a range of –20°C to
40°C in 10K or 1K steps.
2. Excess temperature control
The
D
T function is designed for monitoring temperature sensitive samples.
5K (excess temperature) can be pre-set as the smallest
D
T range.
The maximum adjustable
D
T range depends on the programmed set tem-
perature and is automatically limited by the microprocessor.
If no
D
T is pre-set, the display shows "--".
Attention!
Before activating the
D
T, the entered sample set value must be pre-heated in
order to avoid false alarms.
