Introduction
1.1 Description
The 7161 is a compact pneumatic manifold that provides two output ports with hand-tight
connectors for pressure instrumentation under test. The unit can be used for pneumatic
pressure calibration from vacuum to 200 bar (3000 psi). Features include an anodized
aluminium manifold block and a bleed valve to vent pressure when required.
The manifold is fitted with two hand-tight quick connectors that allow users to connect
devices for test quickly and easily, without the use of wrenches or PTFE tape. The pressure
input port is situated on the rear side of the manifold block, to enable connection to a
contamination trap, pressure controller, calibrator or CalBench module.
The 7161 is ideal to complement Time Electronics calibration benches when pneumatic
pressure modules are fitted in the consoles. The manifold provides an ergonomic and simple
set up for positioning pressure gauges, transmitters and other pressure devices for testing
on the CalBench. It can also situate on the 8100 instrumentation test stand.
Thread configurations are selectable upon request. Standard models have output ports with
2 x 1/4” BSP female (7161) or 2 x 1/4” NPT (7161-NPT). Other threads are available and
manifolds can be built with a combination, for example 1 x 1/4" NPT and 1 x 1/2" NPT.
In addition to the 7161 pneumatic type, hydraulic manifolds are available for use to 700 bar.
Single port versions and custom multi-port configurations are also available upon request.

Warnings
The 7161 manifold is designed for use with pressure controllers, calibrators and regulated
pneumatic pressure systems. These systems control a supplied pressure source and output
them to a unit under test. The 7161 is connected between the pressure source and the UUT.
Please observe all warnings and safety instructions when dealing with high pressure
supplies and outputs. Please ensure that all users of the instrumentation have fully read and
understood operating instructions and safety procedures for handling high pressure systems.
Observe all warnings before operating pressure calibration systems.
The 7161 shall only be used with clean dry air or nitrogen.
Never use hazardous media as pressure medium.
Do not exceed 200 bar (3000 psi) input to the manifold.
Before pressurisation of the 7161, check all components and connections are in good condition,
fully functional and that all screw fittings are firmly. All connections should be suitable for the
applied maximum pressure.
In the case of an error in connections or use, a high pressure or vacuum may be on the input
and output connections. Ensure supplies are vented before working on pressure connections.
During operation, do not disconnect the 7161 when pressure is being applied.
When working on and with the device wear safety glasses.
Use the manifold in the correct orientation on a solid work surface. The bleed valve vents
downwards so exercise with caution when using.
Connections and UUTs damaged from overpressure can cause high velocity shrapnel.
Do not over-tighten the input or output connectors as this can damage the threads.
The 7161 uses a stainless steel valve to vent. This means that the vent valve is fully open or
closed several turns from the end of travel. Over tightening does not increase the effectiveness
of the seal.
Note that this manual refers to the Unit Under Test as the UUT. The UUT should be
connected to the 7161 directly or by using suitable fittings ensuring they are rated for at least
the maximum pressure available from the pressure source.
Time Electronics Ltd do not assume liability for damages that arise from incorrect use of the
instrument device or from disregard of the information contained in this manual.

4.2 Operating Instructions
1. Connect the manifold input to the pressure source (e.g. controller, calibrator, regulator).
As standard, minimess high pressure fittings are used, and hoses are supplied.
2. Ensure no pressure is being applied.
3. Connect the UUT or reference gauge/calibrator to the output ports on the top of the
manifold via the hand tight connectors. If only one port is being used then the supplied
threaded plug can be fitted to close the second port.
4. Ensure the vent valve is closed by rotating the knob clockwise.
5. Gradually apply pressure upon first usage to observe if any leaks are present.
6. To vent the manifold whilst pressure is being applied, turn the vent knob ant-clockwise.
Note that the vent port faces downwards on the valve fitting. Do not obstruct this or
position the manifold so this faces towards the user.
