Rescaling X-Axis
 entering a value next to where it says “X scale (seconds):” adjusts the number of
seconds spanned across the X-Axis, e.g. entering a value of ten seconds sets the X-Axis
so that it will show ten second segments at a time. To use this feature, enter the value
and then click on the “Rescale X-Axis” button. This option can be used at anytime.
Save to File
 the “Save to file” option can be used at anytime once you’ve started the plot program.
The data stored consists of the data collected from the time the Start button was pressed
to the time the “Save to file” button is pressed. The file will be saved in a (.csv) format
which can be later imported into a spreadsheet for further analysis.
Diagnostics Page – Monitor Mode
The Diagnostics Page consists of the Device Diagnostics. In the “Device Diagnostics” section the user is
given the ability to run basic diagnostic tests on the flow, pressure and temperature circuits. These tests can be
run individually or all at once. These tests are explained in detail below.
Device Diagnostics
The tests listed in this section are designed to insure that there are no major electrical problems and that the
sensors are working properly. These tests are described in detail below:
Raw Flow
 this basic test is a simple diagnostic check for the flow circuit to verify that the sensor and
the electronics are working properly. To run this test select the checkbox next to where is
says “Raw Flow:” and then press the “Run the test” button. When the test finishes you will
either see the word “Pass” or “Fail” next to the checkbox. If the test passes, then the flow
circuit is good. If it fails, then there may be a problem.
Raw Pressure
 this basic test is a simple diagnostic check for the pressure circuit to verify that the sensor
and the electronics are working properly. To run this test select the checkbox next to where
is says “Raw Pressure:” and then press the “Run the test” button. When the test finishes you
will either see the word “Pass” or “Fail” next to the checkbox. If the test passes, then the
pressure circuit is good. If it fails, then there may be a problem.
Temperature
 this basic test is a simple diagnostic check for the temperature circuit to verify that the
sensor and the electronics are working properly. To run this test select the checkbox next to
where it says “Temperature:” and then press the “Run the test” button. When the test
finishes you will either see the word “Pass” or “Fail” next to the checkbox. If the test
passes, then the temperature circuit is good. If it fails, then there may be a problem. Please
follow the instructions in the Snapshot section below.
