[. . . ] See Section 9. 2. 2 for information on calculation of the three fluid head correction functions. OPERATION To access various fluid HEAD functions press [SPECIAL], <3head>. The display is: Head menu choices include: <1fluid>: Change the DUT head fluid (see Section 4. 5. 3. 1). <2unit>: Specify the DUT head height unit of measure (see Section 4. 5. 3. 2). <4piston>: Turn the PISTON head correction ON and OFF (see Section 4. 5. 3. 4). Edit head: 1fluid 2unit 3atm 4piston © 2007 DH Instruments, a Fluke Company Page 96 4. GENERAL OPERATION 4. 5. 3. 1 <3HEAD>, <1FLUID> OPERATION To specify the DUT head fluid (see Section 4. 5. 3, PRINCIPLE), press [SPECIAL], <3head>, <1fluid>. The display is: If <1gas> is selected, the display offers the choice of three gasses. Making a gas selection returns to the previous run screen with that gas active for the DUT head function. If <2liquid> is selected, the display offers the choice of oil, water or a user defined liquid. If the user defined liquid is selected, its density must be specified. Making a liquid selection returns to the previous run screen with that liquid active for the DUT head function. Head fluid: 1gas 2liquid Gas type: 1N2 2He 3Air Liquid type: 1oil 2H20 3user In systems using fluid interfaces, the head fluid selected should be the medium used in the height separating the P7601-AF reference level from the device under test. 4. 5. 3. 2 <3HEAD>, <2UNIT> OPERATION To specify the DUT and ATM head height unit (see Section 4. 5. 3, [SPECIAL], PRINCIPLE), press <3head>, <2unit>. The display is: Head height unit: 1in 2cm Selecting the desired unit returns to the previous run screen with that unit active for the DUT and ATM head function heights. 4. 5. 3. 3 <3HEAD>, <3ATM> OPERATION To specify the ATM head height (see Section 4. 5. 3, PRINCIPLE), press [SPECIAL], <3head>, <3atm>. The display is: Edit ATM head unit: -10. 00 cm Entering the ATM head returns to the previous run screen with the new height active. The correct head height when using the PG7601-AF internal barometer as the source for atmospheric pressure measurements (see Section 4. 4) is -10. 00 cm (-3. 94 in. ). The ATM head height is negative if the barometer is below the PG7601-AF reference level and positive if the barometer is above the reference level. The ATM head height unit is set using [SPECIAL], <3head>, <2unit>. The default ATM head height is -10 cm, which is the difference in height between the PG7601-AF reference level and its internal barometer.

Select <1on> to turn the PISTON head correction function ON so that a head correction for piston position IS automatically applied. Select <2off> to turn the PISTON head correction function OFF so that a head correction for piston position IS NOT applied. The PISTON head is automatically turned OFF (has no effect) in gauge measurement mode when the set pressure is zero (system vented). [. . . ] The mass loaded on the piston in terms of the nominal values written on the individual masses. Refers to the "basic system" which includes the complete gas piston gauge calibration system except the piston-cylinder modules and mass set. Refers to the "exchange package" which is the three different size piston-cylinder modules, the mass set and transit cases for shipping them. Refers to the complete, operational PG7601-AF system including the "basic system" (PG7601-BAS-AF) and the "exchange package" (PG7601-EXC-AF). [. . . ]
