Measuring pressure

WARNING:
ALWAYS safely depressurize the system under test before you connect the transducer.
DO NOT connect the transducer to a system that is already pressurized.
ALWAYS check that the transducer is securely fastened to the test port BEFORE you
pressurize the system. ALWAYS check for leaks when you connect the unit.
• Connect the transducer to the hydraulic system, either directly or through a suitable
high-pressure hose.
• Press one of the Range buttons on the transducer to select the desired measuring
range.
• Use a 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
run the appropriate test.
• A waveform showing the pressure of the system will appear on the PicoScope
display.
After a measurement, some fluid may remain in the measurement chamber. When
you disconnect the pressure hose from the transducer, hold both items over a suitable
container to catch any expelled fluid.
WARNING:
DO NOT disconnect the transducer from a pressurized system.
Always replace the sealing cover on the inlet port after use to prevent contamination.

Maintenance

Zeroing the transducer
The WPS600C has a zeroing function to ensure its long-term accuracy. The transducer
may be zeroed before first use, and can be zeroed again if the unit starts to show an
error in the zero-pressure reading.
• Begin with the transducer switched off.
• Disconnect any items that are connected to the transducer's inlet port. Make sure
that the system is depressurized.
• Turn the transducer on and check that the 600 BAR LEDs is lit.
• Press both the 60 BAR and 600 BAR buttons at the same time, then release them.
Both range LEDs will flash for a few seconds, and then the 600 BAR LED will remain
continuously lit.
• The transducer is now zeroed.
