» Calibrate the MaxVenturi weekly when in operation or if environmental conditions change significantly,
i.e., Temperature, Humidity, Barometric Pressure. (refer to Calibration sections of this manual).
» The device will assume a percent oxygen concentration when calibrating. Be sure to apply
100% oxygen or room air concentration to the device during calibration or the device will not
calibrate correctly. (See section 2.2)
