This manual covers the operation and maintenance of the P5513. The Pneumatic
Comparison Test Pump is used for checking pressure-measuring instruments against
Master Test Gauges.
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.

Symbol Description
WImportant Information: refer to manual
Preparation
The comparison test pump should be placed on a stable workbench or similar surface.
Operating Range
The P5513 must be connected to an external gas supply through the ¼ NPT port in the
rear of the instrument case. Typically, dry Nitrogen from a commercially available
compressed gas cylinder is used.
The external pressure supply must be regulated to either the maximum range of the
comparison test pump (3000 psi / 210 bar), or 10% above the maximum pressure required,
whichever is the lower. DO NOT OVER-PRESSURIZE THE COMPARISON TEST
PUMP.

Connections
Fit the device under test (DUT) to the test port using the method described below:
W Caution
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
Dirt/Moisture Trap, (refer to section, Ancillary Equipment).
W 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.
Connections
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.
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 instrume
nt to be tested.

Note
Hand-tight is sufficient; ensure that the bottom face contacts the O-ring on
the test port.
3. To adjust the position to face forward, hold the gauge adapter and turn the instrument
COUNTER-CLOCKWISE, so that it faces forward.

Test Port Insert
For devices with 1/8 BSP or NPT mounting threads, the diameter of the thread is very
close to the effective sealing diameter of the O-ring fitted to the test port.
This can make it difficult to achieve a good seal. When mounting these devices, use the
test port insert (stored in the spare seals container) as shown in Figure 7.

Item Description Part
To calibrate panel-mounted gauges with pressure connections in the rear, use an Angle
Adapter (refer to section, Ancillary Equipment).
Operation
1. To increase the system pressure, slowly open and close Increase Valve until the
desired pressure is reached.
2. The Screw Press can be used for fine control of the system pressure if required, turn
in (clockwise) to increase pressure, or out (counter-clockwise) to decrease.
3. Allow a few moments for the system to stabilize before taking any readings,
especially after large changes in system pressure.

Maintenance and Servicing
Note
Large, sudden changes in pressure will cause the system temperature to
rise or fall, which can cause instrument readings to change as the gas in
the system expands or contracts, thus increasing or decreasing the pressure.
4. For the next higher pressure point, repeat from st
5. To reduce system pressure, slowly open and close Exhaust Valve until the desired
pressure is reached. As before, the Screw Press can be used for fine adjustment of the
system pressure.
6. Before taking any readings, allow a few moments for the system to stabilize as before.
7. After calibration, always vent system pressure by slowly opening the Decrease Valve.
W Caution
Ensure that system is fully vented before removing DUT.
Maintenance and Servicing
W Caution
If the system becomes contaminated with dirt or moisture, this
will transfer to the reference gauge and, potentially, cause
damage to it and the pressure system of the P5513.
If contamination is detected, the system must be disassembled
and cleaned, if left to accumulate, the control needle valves and
screw press may become damaged beyond repair.
Top Plate Removal
1. Turn the capstan fully in, and remove it from the instrument.
2. Remove the four screws that secure the top plate to the instrument case (located in
the center of each edge).
ep 1 above.
3. Tilt the top plate upward at the rear edge, and slide the assembly backward until the
screw press clears the front edge of the case.
4. Disconnect the flexible hose from the inlet valve.
5. The top plate assembly can now be removed from the instrument case.
6. Replacement is the reverse of the above procedure.
Screw Press Servicing
1. Unscrew the large union nut (just behind the inner hub) of the screw press assembl
2. Withdraw the lead screw assembly from the barrel (4), taking care not to drop the
rambler assembly (8).
3. The white, anti-extrusion ring (7) is a PTFE spiral, and can be removed by
“unwinding” it from the rambler.
4. When removing the rambler seal (6), take care not to use any tool that may have a
sharp edge that will scratch the surfaces of the rambler, otherwise it may leak when
reassembled.
5. The replacement rambler seal can be eased over the front of the rambler, and into the
groove.
6. Sim
ilarly, the new anti-extrusion ring can be “wound” into the groo
behind the rambler seal.

7. If it is necessary to remove the barrel, the locknut (3) must be loosened
approximately ½ turn. The barrel can then be unscrewed from the test station (1).
Note
It is often easier to remove the barrel support bracket to allow greater
movement, (remove the 2 screws from the upper side of the top plate).
8. Before re-fitting the barrel, ensure that the barrel seal (2) is correctly located in the
counter-bore in the front of the barrel. Screw the barrel fully in to the test station, and
secure with the locknut.
9. Re-align the barrel support
bracket (if removed), and secure through the top plat
e
with the 2 screws.
10. Ensure that the rambler assembly is correctly located on the end of the lead screw
assembly. Carefully introduce the rambler into the open end of the barrel; making
sure that it does not tilt when entering the barrel.
11. Push the lead screw assembly fully in to the barrel, ensuring that the key in the nut
locates correctly in the slot in the barrel.
12. Re-tighten the barrel union nut.

Angle Adapter, P5543
To calibrate gauges with the pressure connection on the rear (e.g. panel-mount gauges) in
their correct position, an angle adapter should be used. The angle adapter fits directly
onto the test station, converting it through 90 degrees, allowing the standard adapters to
be used.

Pointer Remover/Punch, P5551
To remove and refit the pointer of a pressure gauge, use this tool. This tool has a
spring-loaded plunger to quickly and consistently refit the pointer.
Dirt/Moisture Trap, P5532
Dirt/Moisture Traps provide an effective barrier against the transfer of moisture and dirt
from an instrument under test to the clean pneumatic system of the comparison test pump
and the master test gauge connected to it. Unexpected particle contamination or fluid
inside the device under test will be prevented from entering the test system, avoiding
downtime for maintenance and repair.
