SETTING DISPENSE TIME, PRESSURE AND VACUUM

Shot size is determined by a combination of dispense time, air pressure, vacuum (to prevent dripping
when dispensing thin fluids) and tip size.
Selecting a Memory Cell
Memory cells can be selected on the Main screen as follows:
• Use the Up/Down (8/2) or Left/Right (4/6) keys to highlight the MEM field.
• Press the Enter key, enter the 3-digit cell number (000-399), and press the Enter key again.
• Use the Easy Adjust buttons to increase or decrease the cell number.
Note: Changing to a different memory cell will display the dispense time, pressure, vacuum and
trigger settings stored in that cell and set the regulator to those pressure and vacuum
settings. Any changes to time, pressure or vacuum while in a specific cell will
automatically replace the current settings.
