GaugeCalHP Comparator Operation Manual
3 Fill the reservoir to the fill line.
X Bleed Air from the System
ƒ Tighten the reservoir knob clockwise until fluid comes out of the fittings. The drip tray will collect the spilled fluid.
X 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: For additional sizes and pressure ratings, see the Connection Diagram on page 13.
For applications up to 10 000 psi, create finger-tight, leak-free seals by using CPF fittings. Visit the website for more information on CPF.
Note: If you are using CPF quick test fittings, do not use thread tape.
!
CAUTION: Never use a wrench to tighten quick test fittings.
