PG7000TM OPERATION AND MAINTENANCE MANUAL High pressure liquids and gases are potentially hazardous. Energy stored in these liquids and gases can be released unexpectedly and with extreme force. High pressure systems should be assembled and operated only by personnel who have been instructed in proper safety practices. © 1998 - 2002 DH Instruments, Inc.

[. . . ] These values will be used by PG7000 in calculating defined pressure, piston-cylinder range and pressure to mass and mass to pressure values when the piston-cylinder module is made active by selecting pressing [P-C]. The information needed can be found in the calibration report for the piston-cylinder module. © 1998-2002 DH Instruments, Inc. Page 94 3. GENERAL OPERATION Setting up or editing a piston-cylinder module requires specifying, in sequential order, the following: Serial number (S/N) [nnnn]. OPERATION Adding or editing a piston-cylinder module requires the user to specify a large number of variables in a series of data entry screens described below. For a summary of the piston-cylinder module data requirements in the order they are edited see PRINCIPLE in this section. PG7000 can store up to 18 piston-cylinder module (PC) files. When <3add> is selected and all the files have already been used, a warning is displayed. To create a new piston-cylinder module press [SPECIAL] and select <1PC/MS>, <1PC>, <3add>. Edit each menu to reflect the correct information on the piston-cylinder module being added. Pressing [ESCAPE] at any point offers an <Abandon edits?> query and then returns to the <1PC> menu without saving any of the edited data or returns to the add piston-cylinder module process. The data entry screens to add or edit a piston-cylinder module are, in order: · · Serial number (S/N): Edit the serial number using four digits. Effective area at 0 pressure and 20 °C: Edit the value of the pistoncylinder effective area at 0 pressure and 20 °C. This value is reported in the calibration report for the piston-cylinder module. Piston temperature coefficient: Edit the value of the piston material linear thermal expansivity. The value must be entered in terms of relative change per degree centigrade [nnE-6/°C]. This value is reported in the calibration report for the piston-cylinder module. The default is 00. Page 95 © 1998-2002 DH Instruments, Inc. · PG7000TM OPERATION AND MAINTENANCE MANUAL · Cylinder temperature coefficient: Edit the value of the cylinder material linear thermal expansivity. The value must be entered in terms of relative change per degree centigrade [nn x 10-6/°C]. This value is reported in the calibration report for the piston-cylinder module. Effective area pressure coefficient: Edit the value of the piston-cylinder change in effective area in terms of relative change per MegaPascal [n. nn x 10-6/MPa]. This value is reported in the calibration report for the piston-cylinder module. Piston-cylinder surface tension effect: Edit the value of the surface tension effect of the pressurized fluid on the piston. This value is reported in the calibration report for the piston-cylinder module. [. . . ] The mass loaded on the piston in terms of the nominal values written on the individual masses.
