1.0. PURPOSE

1.1.

THE REQUIREMENTS SPECIFIED HEREIN ARE INTENDED TO ASSURE

THAT MULTIPYCNOMETERS WITH MODEL NUMBER MVP-3 MEET OR

EXCEED THE REQUIRED MANUFACTURING AND QUALITY ASSURANCE

STANDARDS AS SPECIFIED IN THE COMPANY QUALITY MANUAL.

2.0. SCOPE

2.1. THIS PROCEDURE IS TO BE FOLLOWED BY ALL QUALITY

ASSURANCE PERSONNEL INVOLVED WITH MULTIPYCNOMETER TEST AND

CALIBRATION PROCEDURES.

2.2. THIS PROCEDURE CONTAINS CALIBRATION GUIDELINES THAT CAN

ALSO BE FOLLOWED BY QUALIFIED TECHNICIANS, INCLUDING

QUANTACHROME CUSTOMERS, AGENTS AND SALES PEOPLE.

2.3. THESE REQUIREMENTS APPLY TO OTHER MULTIPYCNOMETER MODELS WITH

MODIFICATIONS OUTLINED IN APPENDIX A.

3.0. DEFINITIONS

3.1. MULTIPYCNOMETER: APPARATUS DESIGNED TO MEASURE TRUE

SOLID VOLUMES BY A GAS EXPANSION TECHNIQUE KNOWN AS HELIUM

PYCNOMETRY [ 1 , 2 ].

3.2. QUALITY ASSURANCE: FULL COMPLIANCE WITH PROCEDURES AND

STANDARDS ITEMIZED IN THE COMPANY QUALITY MANUAL.

3.3. SERVICE: GUIDELINES PROVIDED TO ENABLE SERVICE

TECHNICIANS TO HANDLE INSTRUMENT TROUBLESHOOTING.

3.4. MVP - i : MULTIPLE VOLUME PYCNOMETER, MODEL -i .

3.5. VR : KNOWN MANIFOLD REFERENCE VOLUME IN CC’S [ 2 ].

3.6. VC : CELL VOLUME IN CC’S.

3.7. VP: SPHERE OR SAMPLE VOLUME IN CC’S.

3.8. PRESSURE: ALL PRESSURE READINGS ARE DISPLAYED ON THE

DIGITAL PANEL METER AND ARE GIVEN IN PSIG (POUNDS PER SQUARE

INCH GAUGE PRESSURE).

3.9. SPHERES: STAINLESS STEEL BALLS OF VARIOUS SIZES ARE USED FOR

VOLUME CALIBRATIONS. ALL SPHERE VOLUMES ARE GIVEN IN CUBIC

CENTIMETERS (CC`S).

3.10. TOGGLE VALVE: TOGGLE VALVES ARE ON / OFF VALVES LABELED I, II,

GAS IN AND GAS OUT ON THE INSTRUMENT PANEL FACE. VALVES ARE

BRASS CELL HOLDER SEAT. APPLY A VERY LIGHT COAT OF VACUUM

GREASE TO THE O-RING AND REINSTALL IT IN THE CELL COVER.

5.1.2.4. INSPECT THE SAMPLE CELL HOLDER TO MAKE SURE THAT IT HAS NO

SCRATCHES AND VERIFY THAT THE GAS INLET GROOVE IS CLEAN, FREE OF

DIRT AND THAT ITS FLOW PATH IS UNRESTRICTED.

CORCOM FOR 120 VAC OR TO THE SPECIFIED CUSTOMER VOLTAGE

REQUIREMENT. THE CORCOM CARD IS LOCATED BEHIND THE CLEAR PLASTIC

SLIDE DOOR NEXT TO THE POWER SOCKET. TO CHANGE THE VOLTAGE

SETTINGS, SLIDE THE DOOR AND REMOVE THE CARD USING PLIERS. HOLD

THE CARD SO THAT THE VOLTAGE YOU ARE CONFIGURING THE UNIT FOR

FACES YOU, AND SLIDE THE CARD BACK IN THE SLOT.

THE CUSTOMER REQUIRED VOLTAGE) AND TURN THE POWER SWITCH TO THE

“ON” POSITION.

5.2.2.3. USING A CALIBRATED DIGITAL VOLT METER, CHECK AND ADJUST THE

POWER SUPPLY FOR DC OUTPUT VOLTAGE SUPPLIED TO THE CIRCUIT CARD.

THE READINGS ARE TAKEN AT THE POWER SUPPLY TERMINALS AND ARE

REFERENCED TO THE NEUTRAL POST. THESE READINGS SHOULD BE +24.00 

0.01VDC AT THE POST RED & YELLOW AND + 5.00  0.01VDC AT THE POST

COM. & ORG.

5.2.2.4. CONNECT THE VOLTMETER LEADS TO THE PRESSURE TRANSDUCER

PLUG ON THE SMALL PRINTED CIRCUIT BOARD AND VERIFY THAT +24 
