1.2 Function introduction: The electronic peak flow meter is a portable device that can perform lung function tests. It can be used to measure the maximum expiratory flow rate (PEF). The maximum expiratory flow rate (PEF) refers to the highest flow rate during forced exhalation, also known as the highest expiratory flow rate, the maximum expiratory flow rate, and the best expiratory flow rate.
equipment. This equipment should be installed and operated with a minimum distance of 0mm between the radiator and your extremity,60mm for your head. : The patient is an intended operator. The patient can use and maintain the meter and its accessories according to this manual. Put the meter into the specified storage case during transportation. Keep the device out of the reach of children/pets to avoid inhalation or swallowing of small parts.

Insert the mouthpiece into the turbine according to the direction of arrow marked on the mouthpiece, and press it gently to ensure that there is no air leakage at the connection. Remove the accessories and batteries：remove in reverse order. NOTICE: Install the batteries correctly according to the sign of positive and negative terminals in the battery compartment. 3.2. Boot Long press the “ON/OFF” button for 2 seconds until you hear the “DI” sound, prompting the device has been turned on.
Prompt: 1. After the setting of basic information is completed, the device will calculate an estimated value based on your input parameters, which is used to calculate PEF%. 2. The predicted value is not displayed, but PEF% will be displayed after each measurement is completed. 3.3. Testing Deeply inhale and use your lips to wrap the mouthpiece firmly, and make sure that there is no air leakage between the mouth and the mouthpiece.
recommendation to take appropriate treatment measures, such as increasing the dose of medication or seeking emergency treatment. : Please clean mouthpiece according to the Manual Chapter 4 to prevent from dust because of transport or storage when you use the device for the first time. Do not block the air outlet with your tongue or teeth, otherwise the measurement result will be affected. Mouthoiece must be used by one person,don’t cross-use. 3.4 Remeasure Short press the “ON/OFF” button.
time (display in order: month, day, hour, minute). Waiting for about 2 seconds, the interface will automatically display the PEF value in the corresponding history record number (upper line) and PEF% (lower line). The device can store 500 sets of data. When the memory data exceeds 500 sets of data, the device will automatically overwrite the earlier data in the order of the memory data. 3.6 Data Transmission The device can also be connected to communication devices (such as the phone) through Bluetooth.
2) Click "Bond" and then “This APP needs to use Bluetooth” going to pop up.Click “Allow”,the APP will search automatically. When "Connected to: JDY-08" is displayed, the connection is successful.Bluetooth symbol " then appear on the screen of the device. "will 3) The test can be performed according to 3.3 test steps for measurement, and the measured values will be uploaded to the APP synchronously. 4) Click "Got it" to enter the test interface. 5) Repeat the measurements as per steps 1-4.
Click " " in the test interface and select “Personal information” to modify your name, gender, age, height, weight, etc. 3.6 Shutdown Manual shutdown: long press the “ON/OFF” button for 2 seconds until you hear the "DIDI" sound and the screen interface displays "OFF" flashing twice, and the device will shut down.
4 Cleaning and disinfection 4.1 Cleaning of the turbine NOTICE: Do not immerse the turbine in hot or boiling water. To avoid irreparable damage to the turbine, never try to clean the turbine under a direct jet of water or other liquids. Correct operation of the turbine is guaranteed only if it is "clean" and free of foreign objects that affect its movement. The presence of dust or foreign bodies (such as hairs, sputum etc.
cleaning steps untill it is clean.Then wipe it dry with a clean soft cloth. To disinfect the mouthpiece, wipe the clean mouthpiece with an alcohol cotton pad or a cotton cloth moistened with 75% alcohol for 2 miniutes. Allow to air dry on a towel. Finally store it in a clean, ventilated and dry place. 4.3 Cleaning of the main unit Weekly cleaning is recommended. To clean, wipe the device’s surfaces with a soft damp cloth. Dry with a soft cloth, or allow to air dry.
5.3 Storage Please store the electronic peak flow meter in a clean and dry place under the storage environment condition as specified in the manual. Do not place it under the sun or extreme high or low temperature to avoid severe impact. Otherwise, these may cause the device to fail to work normally or even be damaged. 5.4 Waste disposal The meter, accessories and consumables are to be disposed of according to local law or regulation after they have exceeded their service life.
Screen shows “Err 3” Out of measurement range (PEF Value ＞ 999L/min) Remeasure or replace other equipment to measure The display suddenly disappears. The battery is loose. Reinstall the battery NOTICE: If you take the above measures, the electronic peak flow meter still can not be used normally, it is recommended to contact the manufacturer or dealer.
