F).
3.2.1.2. Ramp parameters selection
The SET key works in a sequential way. It is associated with 6 LED
indicators. Each time this key is pressed it allows introducing a different
ramp parameter. The associated LED will indicate which one is being
selected. The ramp parameters available are as follows:
•
Initial frequency value for the 1
st
ramp (Hz). This value acts as the
final value for the 2
nd
ramp.
•
Frequency slope for the 1
st
ramp (Hz/s).
•
Time duration that the final value of the 1sr ramp remains before
the beginning of the 2
nd
ramp (s).
•
Final frequency value for the 1
st
ramp (Hz). ). This value acts as
the first value for the 2
nd
ramp.
•
Frequency slope for the 2
nd
ramp (Hz/s).
•
It is possible to select a frequency value, on which a pulse of 20
ms duration is produced at the
Start Chrono
output (Hz).
3.2.1.3. Start the selected ramp
This key starts the ramp previously selected by pressing the key. This ramp will
stop when it arrives to the programmed cycle or when there is a signal in the
monitor taps.
3.2.1.4. Regulation digit selection
This key works in a sequential way and it is associated with 3 LEDs located
above this press key. This allows the operator to select the output in a fine or
course regulation, by changing the digit to be adjusted.
The following resolutions can be obtained:
•
1 digit.
•
10 digits.
•
100 digits.
When pressing this key for more than 2 seconds, it will block the rotating pulse generator, not
allowing any modifications to the level selected.
3.2.1.5. Rotating control knob
This is a rotating pulse generator and has step by step sensation. The
values can be increased or decreased by turning this control knob
