    Narkomed MRI-2 will not complete an attempted calibration; however, if the calibration gas is rich or lean but is within certain limits, the Narkomed MRI-2 will complete the calibration. As a result, when displaying sensor measurements, the Narkomed MRI-2 displays an oxygen percentage either greater or less than the actual oxygen percentage.
