Inside the finger chamber there is a lens, to get correct and accurate results you need to make sure that the lens is clean.

Unlike traditional invasive Hb devices (Hemocue, EKF etc.) that require a blood sample, the MTX/VSM uses four LED lights to shine wavelengths from visual light through the fingertip. As the light waves pass through the fingertip some of it is absorbed and the light signal is changed. A camera sensor detects the light signal in real time. Using patented algorithms and a vast amount of data, the device analyzes the correlation between the signal and bio-parameters.

The results will appear on the screen after a few seconds, but it is recommended to wait for at least 45 seconds until the device stabilizes.

The device depends on the blood flow in the finger. When the finger is warm the blood flow through it increases, thus improving the measurement.
