Problems taking a measurement

Pressure Sensors and Indicator LEDs
To aid in proper positioning and ensure repeatability of sample measurements, the instrument incorporates three pressure sensors that are integrated into the measurement port. When this option is activated in configuration, an even amount of pressure must be applied across all three sensors before a measurement can occur. The pressure sensor option is typically used when critical instrument positioning in required on a sample.

Positioning feedback is provided by way of three LEDs located on the top of the instrument. The LEDs are arranged in the same pattern as the pressure sensors located in the measurement port. Refer below for LED definitions.

NOTE: The Pressure sensor option must be enabled in Configuration mode.

• LED Off – little or no pressure is being applied to the corresponding sensor.

• LED Amber – not enough force is being applied to the corresponding sensor. You must apply additional pressure to achieve a green LED.

• LED Green – ideal pressure is being applied to the corresponding sensor. A measurement will be taken when all three LEDs illuminate green. If required pressure is not maintained for the duration of the measurement (red or amber LED condition), an error message will
appear on the display and the measurement must be retaken.

• LED Red – too much pressure is being applied to the corresponding sensor. Less pressure
must be applied to achieve a green LED condition.
