Measuring pressure
WARNING
ALWAYS safely depressurize the system under test before
connecting the transducer. DO NOT connect the transducer to a
system that is already pressurized.
WARNING
ALWAYS check that the pressure hose is securely fastened to the
transducer BEFORE pressurizing the system. ALWAYS check for
leaks when connecting the unit and NEVER leave it connected to a
vehicle unattended.
Connect the transducer to the hydraulic system, either directly or through a
suitable high-pressure hose.
WARNING
Use ONLY pressure hoses specifically designed for high-pressure
testing. Pico Technology cannot accept responsibility for damage or
injury caused by the use of unsuitable pressure hoses or adaptors.
Bleed any air out of the measurement chamber.
Use the BNC cable supplied to connect the output of the transducer to the input
channel of the oscilloscope.
Switch on the computer and run the PicoScope software.
In the PicoScope software, select the pressure sensor in the drop-down menu
and then the appropriate pressure test.
If necessary, press one of the Range buttons on the transducer to select the
desired measuring range.
Start the test using the appropriate procedure directed by the manufacturer of
the machine being tested.
A waveform showing the pressure of the system will appear on the PicoScope
display.
Releasing the pressure in the measurement chamber
After a measurement, some pressurized fluid may remain in the measurement
chamber. When disconnecting the pressure hose from the transducer, hold both
items over a suitable container to catch the fluid expelled.
WARNING
DO NOT disconnect the transducer or the high-pressure hose from a
pressurized system.
