Previous Screen Button, Home Screen Button and View Button
Screen for the Guided User Interface (GUI) operation. The Power
ON/OFF button is located on the right side of the meter. The NFC (Near
Field Communication) Tag scanner is a built-in scanner that is used to
scan the NFC card containing the strip (Control and Test Strip) data. Strip
Insertion Area guides the test strip into the meter. Micro USB/Power
Adapter port is a micro USB port used to plug to the power adapter.
Multipurpose USB port can be used to connect the meter to a) portable
printer, b) computer, c) barcode scanner or other Coag-Sense approved

“Troubleshooting” section of this manual or contact Technical Support for
assistance.
Test Strips:
A test strip is inserted and heated in the meter prior to sample application.
The strip contains a tiny wheel with spokes that pull the sample into the
reaction well. The spokes quickly and completely mix the sample with the
clot initiating component of the test strip.
The PT time is determined from when the sample is drawn into the
reaction well of the test strip and is detected by a beam of light until a clot
forms and interrupts another beam of light. The PT seconds result (a true
prothrombin time) is converted to an INR (International Normalized Ratio)
using the INR normalization data communicated by the NFC tag and
subsequently stored in the meter. INR is a mathematical correction of the
