Note
Fluke Calibration recommends having the high pressure generated by the booster be
significantly higher than the desired high-pressure output of the Product. The benefits are
storing high-pressure gas to assure a constant high-pressure output when needed and
minimizing output fluctuation in the regulator. The disadvantage is that an overpressure
condition could occur at the output if the operator improperly sets the high pressure adjust
regulator.
4. Rotate the drive air regulator clockwise until the desired pressure is indicated on the booster drive gauge.

Caution
Maximum shop drive air pressure to the DRIVE port of the drive air regulator should not
exceed 1.7 MPa (250 psi) in the GBK-50M and the GBK-110M. Pressure in excess of this
range may result in an overpressure condition on the inlet side of the high-pressure
adjust regulator.
5. Open the booster drive shut-off valve. The booster begins to operate when the valve is opened. Exhausting gas
noise may startle the operator. Be prepared for this operation.
Increase Pressure
1. Make sure that the high-pressure output is connected to the high-pressure gas point of use. If using the Product
with an 8270A or 8370A Pressure Controller, place the controller in Measure or Vent mode so that there is no
gas flow while setting the regulator.
2. Rotate the high-pressure regulator clockwise until the desired pressure is indicated on the high-pressure gauge.
To correctly set the pressure, gas flow must not occur. If flow is present in the circuit when the regulator is
adjusted, the pressure increases when the flow is reduced.
Decrease Pressure
Note
The high-pressure adjust regulator is a venting type. Therefore, it is possible to regulate
pressure down without gas flow through the regulator.
1. Rotate the high-pressure regulator counter-clockwise until a pressure below the setpoint is achieved as
indicated on the high-pressure gauge.
2. Rotate the high-pressure regulator clockwise until the desired pressure is indicated on the high-pressure gauge
to set the pressure to the final setpoint.
