Pressure Sensors, Indicators and LEDs
To aid in proper positioning and ensure repeatability of sample measurements, the instrument incorporates
three pressure sensors that are arranged around the measurement port. These sensors require an even amount
of pressure to be applied across all three sensors before a measurement is triggered.
Three positioning indicators that appear in the screen as well as the indicator LEDs on the top of the instrument
provide positioning feedback. The indicators in the screen are arranged in the same pattern (top, back and side)
as the pressure sensors located around the measurement port.
•
Green Indicator:
ideal pressure is being applied to the corresponding sensor. A measurement can be
taken when all three indicators illuminate green. If the required pressure is not maintained for the
duration of the measurement, an error message will appear on the display and the measurement must
be retaken.
•
Red Indicator:
the required pressure is not being applied to the corresponding sensor. Correct pressure
must be applied to achieve a green indicator condition.
The circular multi-color LEDs located on the top of instrument provides visual feedback on the status of a
measurement and pressure sensor switches.
•
Green LED
: Indicates all three pressure sensors are activated properly and a measurement can now be
triggered.
•
Red LED
: Indicates one or more of the pressure sensors is not properly activated or an error has
occurred during a measurement.
•
White LED
: Indicates the instrument is being powered on or the AC adaptor is plugged in.
•
Off
: Indicates the instrument is in battery mode or off, not ready to measure, or not in measure mode.
