Pressure Sensors and Indicators
To aid in proper positioning and ensure repeatability of sample measurements, the device incorporates three
pressure sensors that are arranged around the measurement port. These sensors require an even amount of
contact 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 device
provide positioning feedback. The indicators in the screen are arranged in the same pattern (top, back/side) as
the contact sensors located around the measurement port.
Green Indicator:
ideal contact is being applied to the corresponding sensor. A measurement can be
taken when all three indicators illuminate green. If the required contact is not maintained for the duration
of the measurement, an error message appears on the display and the measurement must be retaken.
Red Indicator:
the required contact is not being applied to the corresponding sensor. Correct contact
must be applied to achieve a green indicator condition.
