Contact Sensors, Indicators and LEDs
To aid in proper positioning and ensure repeatability of sample measurements, the instrument incorporates
three contact 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 contact sensor 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, and
back) 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 will appear 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.
The multi-color LED located on the front of instrument provides visual feedback on the status of a measurement
and contact sensor.
•
Green LED
: Indicates all three contact sensors are activated properly and a measurement can now be
triggered.
•
Red LED
: Indicates one or more of the contact sensors is not properly activated or an error has
occurred during a measurement.
•
Blue Pulsing LED
: Indicates the instrument is in standby mode with the USB cable plugged into the
computer and charging.
•
Green Pulsing LED in standby
(screen turned off): Indicates device is being connected to the WiFi
Network.
•
Off
: Indicates the instrument is off and not ready to measure.
