3.3.9 SET UP THE PG7601
3.3.9.1 PREPARE THE PLATFORM AND INSTALL THE PISTON-
CYLINDER MODULE
Connect the PG7601 Terminal to the PG7601 platform rear with 25 pin cable.
Connect the PG7601 power cord from the PG7000 Terminal to the power
strip underneath the bench.
Do not power up the PG7601.
Remove the PG7000 Platform mounting post plug. Unscrew the ORANGE
plastic mounting post plug that is installed in the PG7000 Platform mounting
post. Rotate counterclockwise to remove.
Remove the PC-7100/7600-10, TC piston-cylinder module from its bullet
case. Open the bullet case by rotating its lid counterclockwise. Remove the
piston-cylinder module from the bullet case base by unthreading it from the
case. Hold the piston-cylinder module body by the knurled area and rotate it
counterclockwise.
Place the piston-cylinder module (thread down) into the PG7601 mounting
post (see Figure 27). Rotate the piston-cylinder module clockwise until all
threads are engaged and there is NO gap between the piston-cylinder
module and the PG7601 mounting post. Slight resistance will be
encountered in the second half of travel as the piston-cylinder module
O-rings seat in the mounting post.

3.3.9.2 INSTALL THE AMH-38 MASS SET
The stability over time of PG7601 pressure measurements is a function of
the stability of the masses loaded on the piston. Precautions should be
taken in handling the masses to minimize influences that may change their
mass. This includes always wearing protective gloves when handling the
masses to avoid contaminating them with body oils and perspiration.
Protective gloves are provided in the accessory kit of the PG7601 Platform.
See Section 2.2.1.5 to identify the different elements of the 38 kg mass set.
