INTRODUCTION
Thank you for choosing the HPC40 Series handheld pressure calibrator from Crystal Engineering Corporation. HPC40 calibrators feature deadweight tester
accuracy in a modern digital package with the safest tting connection available. The new full color display also features a new easy to use interface similar to
the one used in the JOFRA ASC-400 Series. The HPC40 is available as a stand-alone calibrator or in one of our complete pump systems, and may be used in a
broad range of applications from simple tool type jobs to complex calibration jobs in custody transfer systems.
Accuracy is up to 0.035 percent of reading
– so one HPC40 can typically replace several gauges or calibrators you may have been using. The HPC40 is fully
temperature compensated
– so there is no change in accuracy throughout the entire operating temperature range!
Single and dual pressure sensor models are available from vacuum up to 15 000 psi / 1000 bar. In addition, the HPC40 features the ability to add an external
pressure port (APM) to provide up to 3 pressure ports. When included with a barometric reference (BARO option), all pressure readings can be displayed as
gauge or absolute readings.
In addition to pressure measurement, the HPC40 also includes a full set of electrical connections. Inputs are included for mA, voltage, switch testing, and
temperature measurement (RTD). An internal 24 VDC supply is also included to power mA transmitters.

PRESSURE SENSORS
The HPC40 Series is equipped with one or two pressure sensors. In addition, a Crystal APM (Advanced Pressure Module) may also be used. For information on
the Crystal APM, please refer to the APM CPF Series Operation Manual. Be sure to choose the proper sensor based on working pressures and accuracy.
! WARNINGS: The following warnings apply to any sensor used with the HPC40 — whether internal or external:
•Pressure sensors may be damaged and/or personal injury may occur due to improper application of pressure. Please refer to the
Ranges and Resolutions table for information on overpressure ratings.
•The calibrator will display
+ OL when an inappropriate pressure is applied. If + OL is displayed, the pressure should be reduced or vented immediately
to prevent damage or possible personal injury.
Note:
+ OL is displayed when the pressure exceeds 110% of the nominal range of the sensor.
Pressure Connection
Crystal CPF System: Medium Pressure Female (MPF) (1/4”medium pressure tube system with 7/16-20 threads). See our CPF Brochure for further information.
CPF o-ring size and material: AS568A-012, Viton 80 or 90 durometer (P/N 3981).
For most applications CPF Fittings can be hand tightened (no tools required). Wrench tightening is recommended (to achieve a metal to metal cone seal) for
applications where chemical compatibility of the process uid and the o-ring are a concern. Cone seals require only moderate assembly torque to seal up to
10 000 PSI (700 bar). We recommend a tightening torque of 120 in-lbs ±20 in-lbs for our CPF ttings. Please note this is only a fraction of the typical torque
required to seal a 1/4”NPT tting. If a torque wrench isn’t practical to use, the ttings can be assembled as follows: Hand tighten tting fully
until the cone has bottomed out, then tighten an additional 20° using a hex wrench. Apply a small amount of media-compatible lubricant to the gland
threads and male cone to increase tting life, reduce the likelihood of galling, and promote sealing.
! CAUTION: To achieve CPF maximum allowable working pressures no o-ring substitutions are allowed. See our CPF brochure and
CES-003 CPF Safety Guide available from the website at crystalengineering.net for further detail.
Measuring Vacuum
All versions of the HPC40 can be used to measure moderate vacuum.
When measuring pressure less than ambient barometric conditions, a minus (-) sign will appear.
! CAUTION: The HPC40 is not recommended for continuous use at high vacuum.

Operation 10
HPC40 Series Operation Manual
Overpressure Conditions
The HPC40 Series will read pressure up to approximately 110% of the rated pressure range. Above 110%, the display will indicate + OL, and readings will stop
updating. The zero function does not aect when the display will indicate
+ OL, so depending on the zero value it is possible that the display will indicate + OL
without the maximum pressure being displayed.
For instance, if a 100 psi range is zeroed when 30 psi is being applied, it will indicate that the overpressure condition has been reached at 80 psi
(i.e., 110% x 100 psi – 30 psi = 80 psi).
Overpressure can aect accuracy, but the eect is only temporary unless the sensor has been destroyed. See the Ranges and Resolutions table for maximum
allowable overpressure ratings.
Measuring Pressure
To Measure Pressure
1 Connect the HPC40 using an appropriate tting.
2 Select one of the pressure modes: P1 , P2 , APM , BARO , or Dual Pres .
For more information on working in the HPC40 display, see Navigating Through a Typical Setup.
3 From the HPC40 display, select the desired pressure units.
Select a pressure mode... then select a pressure unit.
4 Apply pressure to the device under test.

2 Press and hold the (function)button for the sensor that you would like to unzero until the display changes from (- - - - -) to (- - -).
To Clear the Peaks
1 Press the (zero)button to activate the (function)buttons for the available pressure sensors.
2 Press the (function)button for Peaks to reset the P1, P2, and APM peaks.
3 Press the (function)button for the peaks you would like to clear. The Hi, Lo, and Filter will all display (- - - - -).
Note: If you attempt to zero the gauge with more pressure applied than the Zero Limit set on the HPC40 (or with CrystalControl) the command will be
ignored, and Over Zero Limit will display.
Note: The BARO sensor cannot be zeroed.
! WARNING: This calibrator can display zero pressure when connected to a source of pressure! Do not rely on the display indication before disconnecting—
it may not be indicating true pressure. Never disconnect pressure instrumentation without rst relieving system pressure!
Dierential Pressure
The HPC 40 Series can display dierential pressure when 2 or more sensors are installed (including external APM). The modules do not have to be the same full
scale pressure range.

Operation 12
HPC40 Series Operation Manual
To Display Dierential Pressure
1 Select Di. Pres. from the Mode section.
2 Choose the two sensors that you want to use for dierential pressure.
3 Choose the unit for the dierential reading.
For more information on working in the HPC40 display, see Navigating Through a Typical Setup.
4 Apply pressure to one or both sensors to read the dierential.
Dierential Pressure Unit
The two pressure sensors being used can be changed from P1, P2, or APM.
Static Pressure Unit
Note: The static pressure is also displayed on the bottom of the window. The unit for the static pressure does not have to be the same as the dierential unit.
Tare
Using the Tare function improves your dierential measurement uncertainty signicantly if used properly. The Tare function equalizes (normalizes) the
HPC40’s two modules at a non-ambient datum.
If you apply the same static line pressure to both sensors simultaneously, you should have a dierential reading of zero. Due to the allowable error tolerance
for each module, the reading may not be zero. The Tare function allows you to normalize both readings so that the dierential reading is zero. This gives you a
more accurate dierential reading than if this process were not completed.
Note: Tare should be reestablished every time your measurement conditions change, including vent condition. For instance if your ΔP reading has 8 inH20 of
Tare at 1500 psi static, when you return to vent condition this 8 inH20 of Tare will remain in place on your ΔP reading until cleared with the Tare button.
To Tare:
1 Use the (arrow)buttons to navigate to the Dierential Mode view.
2 Press the (zero)button to activate the function button options.
3 Press the (function)button for the ( ) icon.
Note: You will notice that the word Tare is now included on the top right of the display to indicate that the sensors have been tared.
4 To clear the Tare value in the Dierential Mode, hold the (function)button for the ( ) icon for four seconds until the dierential display readings
change from (- - - - -) to (- - -). The tare indication will now be removed from the display.

MEASURING TEMPERATURE RTD
Your HPC40 has the ability to measure temperature very accurately using “true ohm” technology. True ohm resistance measurement eliminates temperature
reading errors by compensating for thermoelectric eects associated with the wires and connections between the RTD and the HPC40. The HPC40 will also
indicate electrical resistance (Ω) to help in troubleshooting your resistance based sensing element.
RTDs are characterized by their 0° C resistance, R0. The HPC40 accepts -2, -3, and -4 wire inputs, with 4 wire input being the most accurate.
The HPC40 is compatible with a large number of platinum RTD probe types. Ametek oers a platinum 100 probe that is ready to connect directly to the
HPC40’s RTD port. See Accessories and Replacement Parts for details.

4 FOR A PRESSURE SWITCH, connect a pump to the HPC40 and then to the switch.
FOR A TEMPERATURE SWITCH, connect an RTD to the HPC40 connection and place the RTD and temperature sensor in a temperature calibrator.
5 Check that the vent on the pump is open, and zero the calibrator if necessary. Then close the pump vent.
The upper display will show no read outs for the Closed, Opened, and Dead band values.
6 Slowly apply pressure or temperature until the switch opens.
Once the switch is open, the switch icon will change to ( ), and the display will indicate pressure at which the switch opened.
Note: In the switch test mode, the display update rate is increased to ten readings per second to help capture the changing switch state. Even with this en-
hanced sample rate, pressurizing the device under test should be done slowly to ensure accurate readings.
