Overview INTRODUCTION     Thank you for purchasing a GaugeCalHP™ Pressure Comparator from Crystal Engineering. The GaugeCalHP is a self-contained, precision hydraulic pressure comparator intended for the calibration of pressure gauges rated up to 15 000 psi / 1000 bar / 100 MPa. You may fill the GaugeCalHP with your choice of water or oil. Using this comparator for calibration is much faster than deadweight testers and most automated pressure controllers. The GaugeCalHP is so quick and easy to use, it is ideal for calibrating those low cost gauges that are often overlooked for ISO9000...

FEATURES AND PARTS LISTS     Each comparator includes a fine adjust for precise pressure adjustments. The reference indicator threads directly to the CPF Male fitting. The device under test connects to the supplied 1/4” Female NPT fitting. For more sizes see the Connection Diagram on page 13 and the CPF Datasheet. Parts Included with the GaugeCalHP Part Number Fine Adjust (installed) Connection Fitting With easy alignment swivel capability. Relief Valve No Mess Drip Tray Captures fluid from bleeding the system. Fine Adjust Easy to use, even at 15000 psi. Pivot Manifold Manifold rotates for...

Setup ASSEMBLY     XX Install the Handle Assembly Install the handle assembly by tightening the captive screw using the included wrench. XX Install the No Mess Drip Tray Press the no mess drip tray onto the pivot manifold. GaugeCalHP Comparator Operation Manual

    The GaugeCalHP includes rubber feet that stabilize the unit up to 5000 psi. At pressures above 5000 psi, the force required to rotate the handle may cause the base of the comparator to lift. One of two methods may be used to mount the GaugeCalHP to a bench or table. XX Using the Mounting Brackets 1 Loosen the mounting bracket screws. 2 Rotate the brackets, then slide them over the front of your table (max thickness of 1.75”). 3 Tighten the mounting bracket screws. Rotate the mounting brackets… then slide them over the front of your table. Note: To ensure the comparator is mounted...

Safety Instructions Follow these instructions for safe and reliable operation of your GaugeCalHP Pressure Comparator. GENERAL CAUTIONS • Avoid knocking, bumping or dropping the pressure system. This can cause permanent damage to the system and loss of accuracy. • The pressure system must not be used for any purposes other than those described in this manual and for any application other than precision pressure calibration jobs. • The pressure system should only be used by TRAINED PERSONNEL. • None of our calibration systems are cleaned or prepared for OXYGEN SERVICE. DO NOT USE our systems...

Operating Instructions GENERATING PRESSURE     XX Prepare the Fine Adjust Turn the fine adjust counter-clockwise about 10 rotations to provide room to increase or decrease pressure as needed. The test fluid can be either water or lightweight oil. Note: If using oil, we recommend AMETEK MGAAA oil. 1 Turn the handle fully counter-clockwise until it stops. 2 Turn the reservoir knob fully counter-clockwise and remove it from the reservoir.

3 Fill the reservoir to the fill line. Fill Line XX Bleed Air from the System Tighten the reservoir knob clockwise until fluid comes out of the fittings. The drip tray will collect the spilled fluid. XX Install the Device Under Test Your GaugeCalHP comes with two CPF male fittings (non-removable) and an adapter to 1/4" Female NPT that is rated to 15 000 psi (P/N MPF15K-1/4FPT). 1 Connect the adapter to your device under test. You will need to use thread tape or sealant to create a leak free seal. 2 Loosely tighten (3 turns only) the other end of the adapter to the connection manifold. Note:...

Operating Instructions   9 XX Install the Reference Indicator 1 Loosely tighten (3 turns only) the reference to the connection manifold. Note: If the reference will not fit because you have a large device under test, turn the pivoting manifold to create extra space. Shown with a Quick Test Fitting (not included). 2 Bleed the system of remaining air by turning the reservoir knob clockwise until fluid drips out of the CPF weep hole on the base of the reference and on the connection fitting. Turn the reservoir knob… until fluid drips from the CPF weep hole. GaugeCalHP Comparator Operation Manual

3 Tighten the reference and the device under test. The connection only needs to be finger tight for a seal to 15 000 psi. 4 If necessary, continue to turn the devices clockwise until they are in the desired position. Note: If necessary, fill the fluid in the reservoir back up to the fill line. 1 Vent the system by turning the reservoir knob counter-clockwise until a gap is visible between the reservoir knob and the lid. 2 Turn on the reference indicator, and then select the pressure units required for the gauge to be tested. For detailed operating instructions, refer to the documentation...
