BASIC FPG HARDWARE SETUP
This process explains critical steps that must be taken prior to using the FPG. The following steps cover
setting the FPG on the calibrating surface, adjusting regulators for proper system pressures, and fine
tuning the system.
Table 3.
Equipment for Basic FPG
Hardware Setup
EQUIPMENT
FPG
FPG piston
FPG cylinder
Bottled compressed gas (air or N
2
)
Regulator (from bottle pressure in / 700 kPa out)
Personal computer
RS232 cable
Various tube’s and adaptors
2.5 mm Allen wrench
Distilled water
Shop air 700 kPa (100 psi)
Place the FPG on the site table with the mounting post facing the back of the table.
Take care not to cause any shock to the FPG by bumping or dropping the unit on the desk. The FPG
contains extremely sensitive measuring components that must be replaced when damaged.
Place the FPG terminal on the table to the right of the FPG.
Add distilled water to the FPG bubbler system. (See Section 8.2).
Connect the FPG terminal to the FPG terminal port on the rear panel of the FPG using the supplied
25-pin cable.
Connect electrical power to the FPG terminal.
Connect an RS232 cable from COM1 of the FPG to an RS232 communications port on the PC.
Level the FPG using the two rear adjustable feet. Use the bubble level on the top of the FPG during
the leveling process.
Connect the supply bottle to the inlet of the external regulator that will be adjusted to 700 kPa (100
psi). It is recommended to have at least 3.5 MPa (500 psi) in the bottle. This will ensure that the
bottle pressure will always be greater than 700 kPa (100 psi).
Do not turn the pressure on the unit at this time. When the FPG is shipped, the piston and cylinder
come detached from the unit. Pressurizing the unit prematurely could introduce contaminates into
the system.
Attach the outlet of the external 700 kPa (100 psi) regulator, to the “lubrication pressure” port on the
back of the FPG.
