Overview  1 —— Overview Introduction Thank you for purchasing a GaugeCalXP™ Pressure Calibrator from Crystal Engineering. The GaugeCalXP is a self-contained, precision hydraulic pressure comparator intended for the calibration of pressure gauges rated up to 700 bar or 10 000 PSI. You may fill the GaugeCalXP with your choice of water or oil. Using this comparator for calibration is much faster than deadweight testers and most automated pressure controllers.

Operation  2 Operation Follow these instructions for safe and reliable operation of your GaugeCalXP Pressure Comparator. 1 Mount the comparator to your bench or table: At higher pressures the force required to rotate the handle may cause the base of the comparator to lift. All dimensions in mm (in) 16.25 (0.34) Baseplate Ø 10.00 (Ø 0.39), 4 places Maximum bolt size: 8mm or 5/16" 142 (5.60) 174.9 (6.88) 19.4 (0.76) 390 (15.35) 428.8 (16.

Operation  4 3 Fill the reservoir: The reservoir holds the test ﬂuid that ﬁlls the system each time you test a gauge. The test ﬂuid can be either water or lightweight oil. Wind the handle fully counter-clockwise, ﬁll the reservoir until it is 25% full. Lift the back of the comparator six inches and tap on the side. The internal trapped air will be removed. The reservoir cap has an o-ring to allow the GaugeCalXP to be transported with the test ﬂuids in place.

Operation  5 10 Start the test: We recommend that you exercise the gauges by applying the full scale pressure of the gauge being tested, one or more times. To apply pressure to the gauges, wind the handle in a clockwise direction. To decrease pressure to the gauges, wind the handle in a counter-clockwise direction. After decreasing the pressure to zero, recheck the ﬂuid level in the reservoir, and rezero the Crystal reference gauge, if necessary.

Operation  6 Remove Air from the System or Generate Vacuum ! WARNING: Do not use this procedure if the test device can be damaged by vacuum. 1 With the Crystal reference gauge in place, remove the device to be tested. 2 Install a short piece of hose going from the device test port to the top of the reservoir. This is to return the ﬂuid expelled to the reservoir. If you do not have a short piece of hose please use paper towels or a shop rag to soak up the excess ﬂuid.
