Overview  1 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.

Overview  2 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.

Setup  5 MOUNTING 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.

Safety Instructions  6 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.

Operating Instructions  7 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. XX Fill the Reservoir 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.

Operating Instructions  8 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.

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.

Operating Instructions  10 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. OPERATION XX Perform a Calibration 1 Vent the system by turning the reservoir knob counter-clockwise until a gap is visible between the reservoir knob and the lid.
PAGE 13
Operating Instructions  11 3 Press the ( zero) button on your reference. We recommend that you exercise the device under test by applying the full scale pressure one or more times. 4 To apply pressure… Turn the handle in a clockwise direction. 5 To decrease pressure… Turn the handle in a counter-clockwise direction. After decreasing the pressure to zero, recheck the fluid level in the reservoir and rezero the reference, if necessary.
PAGE 14
Operating Instructions  12 XX Perform a Quick Test Calibration An alternative method eliminates the time required to wait for thermal pressure stability. This method works with the Crystal XP2i and nVision, but not with the 30 Series. 1 Set the reference to detect peaks and clear any stored peak value. 2 Slowly increase pressure to the first major graduation on the device under test (or to the first calibration point). Increase pressure slowly, so that you don’t overshoot the mark (or point).

Support  15 Support TROUBLESHOOTING Unstable Pressure XX Problem: Pressure cannot be generated correctly, or set pressure does not remain stable. XX Solutions: • • Check that all adapters and pressure fittings have been tightened sufficiently to eliminate leaks. Confirm test fluid does not contain air (air in the fluid can increase adiabatic effects). You may have to adjust the pressure a few times before the pressure is stable enough for calibration. Replace test fluid if necessary.
