9. 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 setting, or the first pumping rate in the Pumping Program.
Otherwise, the calibration defaults to 250 mL at 500 mL/min 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.
The pump uses the entered volume to recalibrate the pumping rate and dispense volume.
Changing the tubing diameter or reseting the pump will cancel the entered calibration. The pump will use
the tube diameter as the calibration value.
10. Setup Configuration
To change or view the setup configuration, the Pumping Program must be stopped. Press the
‘Diameter’/‘Setup’ key until the first parameter, ‘SLO.n’ is displayed. After 2 seconds, or when any non-
arrow key is pressed, the next parameter will be displayed (see sec. 6.14, ‘Setup’ Key). Pressing an arrow
key under a value will increment, select, or scroll through the valid values for the parameter. The Setup
Configurations will be displayed in the following order:
n
Slow Down mode, where ‘n’ is the current setting.
n
Anti-Drip mode, where ‘n’ is the current setting.
n
Dispense and pause mode, where ‘n’ is the current setting.
nn
When pasue mode is enabled, displays the pause setting.
Display secondary setup menu: Press any arrow key to select.
n
Power Failure mode, where ‘n’ is the current setting.
n
Alarm mode, where ‘n’ is the current setting.
