SAFETY SUMMARY
The following are general safety precautions that are not related to any specific procedures
and do not appear elsewhere in this publication. These are recommended precautions that
personnel must understand and apply during equipment operation and maintenance to
ensure safety and health and protection of property.
COMPRESSED LIQUID
Use of compressed liquids can create an environment of propelled foreign matter. Pressure
system safety precautions apply to all ranges of pressure. Care must be taken during testing
to ensure that all hydraulic connections are properly and tightly made prior to applying
pressure. Personnel must wear eye protection to prevent injury.
PERSONAL PROTECTIVE EQUIPMENT
Wear eye protection approved for the materials and tools being used.

SECTION 1.0
PREPARATION
The Comparison Test Pump is used for checking pressure-measuring instruments against
Master Test Gauges.
Note: The terms ”Master Test Gauge” and “Gauge” in this document refer to any pressure-
measuring instrument such as Transfer Standards, Digital Calibrators and
Transducers.
This system is only as accurate as the Master Test Gauge used. The Master Test Gauge
must be regularly calibrated on a Primary Reference Standard (such as a Deadweight Tester)
to ensure accuracy is maintained.
The comparison test pump should be mounted securely to a stable workbench or similar
surface. Four mounting holes are provided in the pump stand for this purpose.
1.1 OPERATING FLUID COMPATABILITY
The standard system is designed for use with a wide range of fluids, however, the O-ring
seals are Nitrile; use of solvents, fuel oils, brake fluids or other, similar aggressive fluids can
damage the seals. The table below details the two alternative versions of this instrument,
which offer increased compatibility with other fluids.
Model O Rings
5514 Nitrile
5514-V Viton
5514-EP Ethylene Propylene
Rotate reservoir dust cover through ½ turn and fill reservoir approximately ¾ full with the
appropriate fluid. Rotate dust cover back to cover reservoir.
WARNING
To avoid damage to the instrument, the operator should check the quality of the operating
fluid during use. If the fluid becomes discolored, cloudy or particles appear in the reservoir,
the system should be drained and flushed with clean fluid.

SECTION 2.0
CONNECTIONS
Fit the device under test (DUT) to the test port using the method described below:
IMPORTANT
Ensure that all devices are internally clean and free from contamination before connecting
to the tester.
Particle contamination can damage the sensitive piston assemblies, valve seats and screw
pump.
To avoid cross-contamination from other fluids, and protect the system from particulates,
we recommend the use of a Liquid-to-Liquid Separator, (Refer to section 9.0, Ancillary
Equipment).
WARNING
DO NOT use Teflon/PTFE tape on these connections, as this will prevent correct sealing. The
Gauge Adapter sealing system is designed for hand-tight sealing up to 20,000 psi / 1,400 bar
- wrenches or similar tools are not required – over tightening can cause damage to threads
or sealing faces.
Before connection, ensure that there is an O-ring fitted to the test port.
Check that the sealing face of the device to be fitted is clean and undamaged, as scratches
or dents can form leak-paths.
2-1 CONNECTIONS
NOTE: The thread on the test port, and the lower part of the gauge adapters is LEFT-
HANDED. The following procedure details the correct method for mounting devices
using these adapters: -
1. Screw the appropriate gauge adapter
fully on to the instrument to be tested.
2. Screw assembly down COUNTER-CLOCKWISE
on to test port.
Note:
Hand-tight is sufficient; ensure that the bottom
face contacts the O-ring on the test port.
