Page 5: About This Manual
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. - Page 6 PG7607™ OPERATION AND MAINTENANCE MANUAL Notes © 2010 Fluke Calibration Page vi...

Page 7: Introduction
Introduction 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. -

PG7607 mounting post. To operate the PG7607 platform, a piston-cylinder must be installed on its mounting post. To install a piston-cylinder assembly on the PG7607 platform, follow the sequential procedure below. This procedure may be used on the first and subsequent piston-cylinder installations;... - Page 12 Avoid touching the WHITE cylinder centering ring (15) as it will eventually contact the critical inside surface of the cylinder. Check that the lower piston sealing O-ring (10a) is installed. The PG7607 platform is delivered with the lower and upper piston sealing O-rings (10a, 10b) and O-ring carriers installed loosely in the recess on the mounting post.

Tighten the cylinder retaining screw (2). Using a 5 mm Allen tool (one is supplied in the PG7607 accessories), tighten the cylinder retaining screw (2) into the cylinder stroke limiter (16) of the piston retaining assembly (5). Turn the screw CW to tighten. Since the cylinder stroke limiter (16) is free to move within the piston retaining assembly (5), the retaining screw (2) may rotate with the assembly, failing to tighten. - Page 14 PG7607™ OPERATION AND MAINTENANCE MANUAL Notes © 2010 Fluke Calibration Page 8...

TEST port should also be applied to the CCP port. PG7607 allows an independent pressure to be applied to the inside of the piston. The purpose of this feature is to allow the piston to be artificially expanded, varying the size of the gap between the piston and cylinder. The ability to predictably vary the size of the gap between the piston and the cylinder can be useful in analyzing piston-cylinder behavior. - Page 16 PG7607™ OPERATION AND MAINTENANCE MANUAL Notes © 2010 Fluke Calibration Page 10...

• The cylinder assembly (cylinder + cylinder cap + adjusting mass + cap retaining screw + cylinder retainer) is part of the PG7607 mass load. Its mass has been measured and is reported in the calibration report. When handling these parts, take care not to change their mass by swapping parts, contaminating them or leaving parts out in reassembly. -

Water/detergent method: Due to the piston-cylinder’s large diameter and very small annular gap, it is very difficult to insert the piston into the cylinder when the piston is not installed on the PG7607 mounting post. Without the alignment mechanism provided by the mounting post arrangement (see Figure 1) there is a substantial risk of cocking the cylinder on the piston. -
