Setting the Shaking Frequency

1. Switch into "Frequency-Mode" with key [
the unit is in "Timer-Mode".
2. Enter the shaking frequency required via the numerical
keys. The value range is:
Mikro-Dismembrator S
100...2.600
continuous mode
3. Confirm the entry with the [ENTER] key. Wrong inputs
can be easily corrected. Press deletion key [ C ] to
change the actual entry. The cursor starts with the last
(right hand) digit of the display, ready for a new entry.
Confirm new entry with the [ENTER] key.

] ]
1. Switch-over to "Timer-Mode" with either key [
[ ] if the Mikro-Dismembrator S is in "Frequency-
Mode".
2. Enter the operation time in [Min:Sec] via the numeric
key pad. The timer value range is 00:01 ... 98:59
[Min:Sec]. Press the [ENTER] key to confirm the value
time. For a quick entry of the time, you may confirm
after input of [Min].
3. Wrong inputs can be easily corrected. Press deletion key
[ C ] to change the actual entry. The cursor starts with
the first (left hand) digit of the display, ready for a new
entry of [Min]. Confirm new entry with the [ENTER] key.
•
The Mikro-Dismembrator S remains inactive at an input
of 00:00 [Min:Sec]. Illogical inputs will be ignored, such
as 00:70 [Min:Sec], for instance. The input of 99:59
[Min:Sec] switches-over to "Timer-Mode" for
continuous operation.
