Using Steady Mode to Dispense a Dot or Stripe or Fill a
Cavity
1.
Start with pressure set to zero.
2.
Place the syringe barrel over a piece of paper or test surface.
3.
Place the unit in “Steady” mode.
4.
Unsnap the safety clip. Depress and hold the foot pedal for the remainder of setup.
5.
While resting the tip on the paper (test surface), increase the air pressure by 0.069–0.138 bar
(1–2 psi) using the keypad until you have reached the desired fluid dispensing flow rate.
NOTE:
Always use the lowest possible pressure and the largest possible tip size. The
combination of the lowest possible output pr largest possible tip size + longest
possible dispense duration = most consistent and accurate deposits.
6.
Release the foot pedal.
7.
Retest the dispensing rate a few more times. Fine tune as required by making small changes
in pressure.
