Drifton 206-DF - Setup for Testing

When you begin testing, the Power switch should be off.

The amount of material dispensed in each cycle depends on the combination of air pressure, time of air

pulse, viscosity of material and dispensing tip size.

The first step is to remove the tip cap from the prefilled barrel of test material. Replace it with a 14 gauge

tapered dispensing tip. Press the tip on and twist clockwise to lock.

Second Pull out air pressure regulator knob until it "clicks" into the unlocked position. Turn clockwise to

adjust the air pressure to 30 psi (2.1bar) for the initial tests.

Always set the pressure desired by turning the air regulator knob clockwise. To reduce the pressure, turn the

knob counterclockwise until the gauge reads a lower pressure than desired. Then increase and stop at desired

pressure. Push knob in to lock.

Pressure regulator Turn clockwise - increase pressure

Turn counterclockwise - decrease pressure

Third: Press power switch to turn on the dispenser.

Fourth: Press the "Auto/Man" button to choose the "Man". The time display will automatically show the

best bits of time. (example: 0.100 seconds), then press any one of 1-8 to set the time, already almost

complete set of quantitative, touch the foot switch every time to drop a quantitative fluid.

Fifth: Multi-function: Can set the size of eight different points, according to the fourth step to set the size

you want of eight different dots. Press the point size you want, it will set the size according to you for

dispensing.

Sixth: Be sure the barrel vacuum control is turned off. The vacuum volume should be "0" when testing.

If you want to test vacuum suction, take some water in the barrel firstly and fasten the tip, then adjust the

vacuum regulator. When your turn it counterclockwise, you will find that the water doesn't drip. If the

suction of vacuum is too high, the water will rise into the barrel.
