Tubing Calibration
Calibration mode fine tunes the dispense accuracy. Continued use of tubing will cause it to stretch and
deform which creates dispensing errors. Also, differing viscosities and/or pumping speeds can also affect
pumping accuracy.
Calibration uses the currently selected dispense program. Also, you will need a calibrated measuring cup
to verify the actual dispense volume.
To begin calibration: While turning on power, press and hold the ‘LEARN’ key until the display shows:
Press any up arrow key for the next Learn selection: Calibration:
Press the ‘Start’ key to begin the dispense.
When the dispense is complete, the pump will stop, and the dispensed volume will be displayed with the
volume units LED blinking.
Press the ‘LEARN’ key to accept this volume, or use the up arrow keys to enter a measured dispense
volume.
Press ‘LEARN’ after the measured dispense volume has been entered and to store in memory.
The pump is now calibrated. Dispense volumes and pumping rates will be adjusted according to the
measured volume entered.
Tubing Inside Diameter Setting
For most applications, the default tubing inside diameter does not need to be changed since the standard
pumping head is optimized for 3/16” inside diameter (ID) tubing.
If needed, to change the tubing diameter setting, enter Diameter Setting mode:
While turning on power, press and hold the ‘Diameter’ key until the display shows:
Press the ‘DIAMETER’ key again to select. The display will show the current diameter and the ‘Inches’
units LED will blink. While the units LED is blinking, use the up arrow keys to enter the new diameter as
a fraction of an inch. For example, to enter 1/16” id tubing, use the up arrow keys to change the display
to:
Press the ‘LEARN’ key, or wait for the time out to enter the new setting. The tubing diameter will now
be set to the new setting. The new diameter will be used as the current calibration setting.
Special Modes
Press and hold the ‘Diameter’/’Setup’ key to access the Special Modes setup menu The first mode,
“Slow-Down” will be displayed:
n
Press the ’LEARN’ key to move to the next mode, or wait for the time out. The following is the sequence
of diplays:
n
Slow Down mode, where ‘n’ is the current setting.
n
Anti-Drip mode, where ‘n’ is the current setting.
