Calibrate
3.2.2 RS-232 Serial Settings
Foxy
The factory calibration positions the drop former over the col-
lection tubes for all available rack types. Calibration is not nec-
essary for most applications and commercially-available
collection vessels.
Some applications or collection vessels require calibration to
further refine the drop former position. This need is evident
when the drops fall on or beyond the rim of the collection vessel.
Note
If the only drops that fall on or beyond the rim are those imme-
diately following a tube advance, the problem is not due to cal-
ibration. Instead, lowering the drop former (section 2.4) or
adjusting Tube Advance Speed might prevent this condition.
Additionally, consider stopping the fluid delivery pump during
tube changes (Section 3.2.5).
Should calibration be necessary:
1. Ensure that the fraction collector is level.
2. Load the rack with the collection vessels and place the rack
on the system.
3. Touch the Calibrate icon to access the calibration options.
4. Touch the First Tube icon to move the drop former over the
front and left-most tube in the rack.
5. Touch the Arrow buttons to incrementally position the
drop former over the center of the collection vessel opening.
Note
The white diverter valve housing has a arrow on the face to
indicate the center of the drop former outlet. This can assist
with the left-to-right (X-axis) positioning.
6. When the first tube position is calibrated, touch the Last
Tube icon to move the drop former over the back and
right-most tube.
7. Touch the Arrow buttons to position the drop former over
the center of the collection vessel opening.
8. Touch the enter icon to save the calibration settings.
By calibrating the drop former position over the first and last
tubes, the fraction collector calculates the position of all other
tubes in the rack.
External devices can communicate with the fraction collector.
One option is through the RS-232 Serial port. Many of the com-
munication parameters are predefined by the firmware:
• Supports ASCII printable characters
• 8-bit
• No parity bit
• 1 stop bit.
