About This Manual
This manual is designed to be used in conjunction with the PG7000 Piston Gauges Operation and
Maintenance Manual, to operate a PG7607 Piston Gauge.
PG7607 is identical in conception and features to a PG7601 piston gauge. PG7607 differs only in the piston-
cylinder mounting post and the piston-cylinder module as PG7607 is designed to exploit a unique 50 mm
diameter piston-cylinder. This manual covers the aspects of PG7607 that are different from PG7601.
To operate a PG7607, use the PG7000 Piston Gauges Operation and Maintenance Manual and follow the
instructions and information applying to PG7601. Refer to this manual for details on the piston-cylinder
mounting post and piston-cylinder module.
Note
In PG7607, the CYLINDER rather than the PISTON floats and is rotated. When
using the PG7000 Manual to operate PG7607, references to the PISTON of PG7601
apply to the CYLINDER of PG7607.
Manual Conventions
Caution
“Caution” is used in throughout the manual to identify conditions or actions that
could cause harm to the PG7607 or to the devices that are connected to it.
Warning
“Warning” is used in throughout the manual to identify actions that could pose a
hazard to the user of the PG7607.
Note
“Note” is used throughout the manual to identify operating and applications advice
and additional explanations.

1. Introduction
1.1 Product Overview
PG7607 is a special model in the PG7000 line of piston gauges. PG7607 is identical to PG7601 except
for its piston-cylinder and mounting post.
PG7607 was designed to exploit a unique 50 mm diameter piston-cylinder. With this piston-cylinder, the
piston is mounted in a fixed position in the mounting post and the cylinder floats and is rotated.
A controlled clearance pressure can be introduced into the mounting post allowing the piston diameter and
thus the gap between the piston and cylinder to be varied.
PG7607 is available on a limited basis and, generally, is only offered for use in national measurement
institutes or other laboratories performing fundamental research in pressure metrology.
Note
This manual is intended to be used as a supplement to the PG7000 Manual.
PG7607 is identical to PG7601 except for its piston-cylinder and mounting post. To
operate a PG7607, use a PG7000 Operation and Maintenance Manual and apply the
information on PG7601 referring to this manual for piston-cylinder and mounting
post information. Also keep in mind that in PG7607, the CYLINDER, rather than the
PISTON, floats and is rotated. References to the PG7601 PISTON in the PG7000
Manual apply to the CYLINDER of PG7607.

2. Installation
2.1 Unpacking and Inspection
2.1.1 Removing From Packaging
PG7607 is delivered (along with its standard accessories) in a reusable molded transit case
with polyurethane inserts to hold it in place.
Remove the PG7607 and its accessories from the shipping container and remove each
element from its protective plastic bag.
2.1.1.1 Piston-Cylinder Assembly
The piston-cylinder assembly is shipped in a molded plastic case with custom
polyethylene inserts that accommodates 2 Acetal bullet cases. The piston and
the cylinder are separate; each is packed in its own bullet case. Do not handle
either of these elements with your bare hands. Use the gloves that are in the
PG7607 accessory kit or use the lint free wipes.
Caution
Never handle the piston or cylinder with bare hands. Oil and
acids from bare skin can damage the critical surfaces (polished
appearance).
