Clear OLED display You can read the parameter including SpO2, pulse rate, bar graph, synchronous waveform, heart beep mark, pulse beep and the capacity of battery from dual color OLED display screen. Easy to use Simply insert your finger to the probe of this digital oximeter and press the only button to start measuring. Auto shutdown system Thanks to its intelligent mechanism, this portable oximeter can automatically turn off the display within 8 seconds when there is no signal. Suitable for all ages The wide range of finger sizes enable both children and adults to use especially for those sports enthusiasts and ones who are interested in their general health and wellness. Widely used and portable Fits for family, hospital, clinical institution and health-care community. A little bag and a lanyard included in the accessories can protect it from damage and make it convenient to be carried. How to use: Open the battery cover, and put 2 AAA batteries into battery compartment in correct polarities, then replace the cover. Gently press the bottom of the equipment to turn on, and open the probe, then insert one finger into the probe. After about 10 seconds, the measurement result can be read directly from the display screen. Notes: Normal SpO2 values vary between 95 and 100 percent. If your SpO2 value is below 95 percent, that could be a sign of poor blood oxygenation, also called hypoxia. Long press the button for 2 seconds can close the pulse sound, and long press the button can open the pulse sound again. Only FA20A can switch the display directions by pressing the button in the normal measure state.   Item Type: Blood Pressure For (Blood pressure): Finger Voltage (V): DC 3 Wristband Range: 38cm   Package weight: 0.096 kg Product Size ( L x W x H ): 3.50 x 3.10 x 6.20 cm / 1.38 x 1.22 x 2.44 inches Package Size ( L x W x H ): 11.80 x 3.80 x 7.70 cm / 4.65 x 1.5 x 3.03 inches Package Content: 1 x Fingertip Pulse Oximeter, 1 x Protective Bag, 1 x Lanyard, 1 x English Manual     IPXX Rating Chart IP Code The IP Code (or International Protection Rating, sometimes also interpreted as Ingress Protection Rating*) consists of the letters IP followed by two digits and an optional letter. As defined in international standard IEC 60529, it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures. The standard aims to provide users more detailed information than vague marketing terms such as waterproof. The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. For example, an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. IP22 or 2X are typical minimum requirements for the design of electrical accessories for indoor use.
