(14), unscrew it (rotate CCW) fully from the mounting post and remove it. Avoid touching the WHITE cylinder centering ring (15) as it will eventually contact the critical inside surface of the cylinder. Page © 2008 DH Instruments, a Fluke Company... - Page 12 The cylinder centering ring (15) aligns the cylinder on the piston facilitating the insertion process. Allow the cylinder to slip all the way down the piston until it reaches end of stroke. © 2008 DH Instruments, a Fluke Company Page 6...
- Page 13 Be sure the cylinder retaining screw (2) is tightened before applying pressure to the piston- cylinder. The cylinder stroke limiter (16) limits the cylinder’s upward movement preventing it from coming off the piston. Page © 2008 DH Instruments, a Fluke Company...

When using a AMH-38 with the PG7607, the PG7607 reference level is 3 mm below the reference level marked on the AMH vacuum chamber. This is because the AMH-38 is marked for the PG7601.

The piston retaining assembly (see Figure 2) does not need to be disassembled as part of routine maintenance. However, the piston retaining assembly captivates the cylinder stroke limiter that is part of the of cylinder assembly whose mass must be determined when recalibrating the cylinder. © 2008 DH Instruments, a Fluke Company Page 12... -
