1500XL -- Setup for Testing
❶
Power switch should be off.
The amount of material dispensed each cycle depends on the
combination of air pressure, time of air pulse, viscosity of material
and dispensing tip size.
Note: The following steps refer to the 1500XL dispenser. For the
1500XL-15 and 1500XL-CA dispensers, refer to "Making Timed
Deposits of Watery-thin Fluids" on page 22.
The first step is to remove the tip cap from the prefilled barrel of blue
test material (twist and pull). Replace it with an 18 gage (green)
tapered dispensing tip. Press the tip on and twist clockwise to lock.
Pull out air pressure regulator knob
unlocked position. Turn clockwise to adjust the air pressure to 30 psi
(2.1 bar) for the initial tests.
Always set the pressure desired by turning the air regulator knob
