Speed Setting and Rotation Display
The Vortex-
d
has a rotary speed controller for both
clockwise and counter-clockwise rotations. Speed is set and
controlled by the control knob on the front panel and
indicated on the digital display.
The digital display on the control panel will allow actual
speed (in revolutions per minute, i.e rpm) to be displayed.
Speed values displayed are distinguished between
clockwise and counter-clockwise rotation. If the platen is
rotated one revolution clockwise, then half a revolution
counter-clockwise, 180º will be displayed, i.e.
it is the
absolute rotation which will be displayed.
The Vortex
-d
can be run in manual mode only. To set-up
speed, press the
Mode
key for 2 seconds until the speed
indicator starts to flash on the digital display. Change the
speed by moving the control knob clockwise or
counter-clockwise in increments of 0.1rpm.
Press the
Mode
key again to move down on the digital
display and change the speed by moving the control knob
clockwise or counter-clockwise in increments of 0.1rpm.
Press the
Mode
key once more and the displacement unit
will flash; then select the displacement unit desired (rev or
deg) by moving the control knob clockwise or counter-
clockwise.
To save time when setting the speed to a minimum or
maximum level, turn the control knob quickly to reach the
maximum speed of 20rpm or minimum speed of 0.1rpm.
Press the
Zero
key to store settings and exit.
Pressing the
Zero
key will reset degrees or revs displayed to
zero.
