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).
4
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
CLOSED WHEN THEIR HANDLES ARE PARALLEL TO THE CABINET FACE AND
OPEN WHEN PERPENDICULAR TO THE CABINET FACE.
3.11. NEEDLE VALVE: TWO ADJUSTABLE NEEDLE VALVES PERMIT FLOW
RATE CONTROL THROUGH GAS IN AND GAS OUT. TURNING THEIR KNOB
CLOCKWISE REDUCES THEIR RESPECTIVE FLOW RATES.

UNDER THE SAMPLE CELL HOLDER COVER. CLEAN THE COVER AND THE
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.

5.2. POWER CHECKS
5.2.1. AC CHECKS
5.2.1.1. CAUTION -THESE CHECKS MUST BE PERFORMED WITH THE POWER
SWITCH TURNED OFF AND WITH THE POWER CORD UNPLUGGED. THESE
INSTRUCTIONS SHOULD ONLY BE PERFORMED BY TRAINED PERSONNEL AND
THEN ONLY AFTER TAKING ALL PERTINENT SAFETY PRECAUTIONS.
5.2.1.2. SET THE POWER SWITCH TO THE OFF POSITION AND CONFIGURE THE
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.
5.2.1.3. USING AN OHM METER, TEST FOR CONTINUITY ACROSS THE LINE
INPUT TERMINALS. THE READING SHOULD BE INFINITY (OPEN CIRCUIT).
5.2.1.4. USING AN OHM METER, TEST FOR CONTINUITY BETWEEN THE INPUT
LINE TERMINALS AND THE CHASSIS GROUND. THE READING SHOULD BE
INFINITY (OPEN CIRCUIT).
5.2.1.5. USING AN OHM METER, TEST FOR CONTINUITY BETWEEN THE INPUT
GROUND TERMINALS AND THE CHASSIS GROUND. VERIFY A READING OF
CONTINUITY INDICATING A SHORT CIRCUIT.
5.2.1.6. SET THE POWER SWITCH TO ON. USING AN OHM METER, TEST ACROSS
THE LINE INPUT TERMINALS. THE READING SHOULD BE AROUND 17 OHMS. IF
A SHORT IS READ THE SWITCH MAY BE WIRED INCORRECTLY.
THE READING SHOULD BE AROUND 68 OHMS IF THE VOLTAGE IS 220V-240V.

PRINTED CIRCUIT BOARD (PART NUMBER 00003) LOCATED INSIDE ON THE
LEFT BULKHEAD.
5.2.2.2. CONNECT THE INSTRUMENT TO THE 120 VAC SUPPLY OUTLET (OR TO
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
0.01VDC ARE MEASURED ACROSS PINS 4 AND 6.
5.2.2.5. TURN THE POWER SWITCH TO OFF AND THEN RECONNECT THE
PRESSURE TRANSDUCER CONNECTOR TO THE SMALL PRINTED CIRCUIT
BOARD.
5.3. ALIGNMENTS
5.3.1. DIGITAL PANEL METER
5.3.1.1. TURN THE INSTRUMENT’S POWER SWITCH TO ON. VERIFY THAT THE
DIGITAL PANEL DISPLAYS NUMBERS THAT ARE BRIGHT AND CLEAR.
5.3.1.2. TURN THE ZERO ADJUSTMENT KNOB ON THE FRONT PANEL FROM
STOP TO STOP SLOWLY AND VERIFY THAT SMOOTH DIGITAL CHANGES OCCUR
AND THAT ALL SEGMENTS OF EACH DIGIT ILLUMINATE.
5.3.1.3. TURN THE ZERO ADJUSTMENT KNOB ON THE FRONT PANEL TO THE
MID-RANGE POSITION (5 TURNS FROM THE STOP FOR A TYPICAL 10 TURN
POTENTIOMETER).
5.3.1.4. TURN THE SELECTOR VALVE TO THE CELL POSITION AND OPEN THE
GAS OUT TOGGLE VALVE TO VENT THE CELL. AFTER 5 MINUTES OF WARM UP
TIME ADJUST RESISTOR R1 LOCATED ON THE SMALL PRINTED CIRCUIT
BOARD FOR A READING OF 0.000 PSIG ON THE DIGITAL PANEL METER. THIS IS
PERFORMED BY PLACING A JEWELER’S SCREWDRIVER THROUGH THE HOLE IN
THE BACK PANEL AND TURNING THE POTENTIOMETER UNTIL THE DIGITAL
PANEL METER READING DISPLAYS 0.000 PSIG.
5.3.1.5. PLACE A SMALL AMOUNT OF TORQUE SEAL BETWEEN THE
ADJUSTMENT KNOB AND THE BODY OF THE POTENTIOMETER R1 TO INSURE
THAT IT REMAINS UNCHANGED DURING SHIPMENT.
