Daily activities, such as food, exercise, and dehydration can affect measurement results. Oserio recommends measuring weight and body fat in the morning, to minimize variables and receive the most reliable and consistent results.

Ideally, you should conduct measurements in the same environment and time of day, to further reduce variables and receive the most accurate body composition calculations.

Oserio body fat scales utilize Bioelectrical Impedance Analysis (BIA) to calculate body composition. BIA should not be used by subjects with the following characteristics:

(1) Electronic medical implants, e.g. cardiac pacemaker
A low level imperceptible electrical current will be sent through the body during measurement, which may damage the implanted device or result in malfunction.

(2) Prosthetics and amputation
BIA measures impedance measured using an electric current sent through the body through electrode contact points. As the current cannot flow through prosthetic limbs, measurement is not possible.

(3) Pregnant Women
BIA equations are created based on statistical analysis of sample populations. If subject's body composition differs significantly from these sample populations, equations derived from "normal" healthy adults will be inherently less accurate in these subjects. Women undergo a wide range of body composition changes during pregnancy, including but not limited to change in fat percentage and body water. Without dedicated algorithms, pregnant women should use results with caution and professional advice.

Before measurement, a scale should be placed on a flat, solid, non-slippery floor. If used on carpet or uneven ground, measurement results may be less accurate.

We recommend using alcohol-based wipes to clean our products. Please avoid using large amounts of water, corrosive liquids, or high pressure washers during cleaning, as this may damage the internal electronics. Always disconnect the device from the mains power supply before cleaning to minimize risk of electric shock.

Bioelectrical Impedance Analysis (BIA) is a safe and well-established technology for calculation of body composition. BIA sends a safe, imperceptible electrical current through the body, measuring impedance as it travels through different body tissue. Oserio's algorithms then combine measured data (impedance, weight) with input data (ex: height, age, weight, gender) to calculate body composition.

Why does this work? BIA utilizes the fact that water is a good conductor of electricity to calculate results. For example, fat has low conductivity, whereas muscle (being high in water) has better conductivity.

If input data is incorrect (ex: height), measurement results may be less accurate!

由於體脂肪是無法藉由目測或一般方式測量，最常用的推算技術為生物阻抗分析 (Bioelectrical Impedance Analysis / BIA)。生物組抗分析測量電流通過身體遇到的阻抗；方程式藉由阻抗和其他參數（例如：身高、年齡、體重、性別）利用水分導電性高、脂肪導電性低的原理，結合大量資料庫分析，計算身體的脂肪、肌肉、水分等其他體組成結果。

因此如果輸入的資料不正確 (例如身高)，可能會造成依定程度的計算誤差！

1. 醫療器材許可證

以生物阻抗法為原理的體脂計，是歸屬於第二等級的醫療器材。依藥事法第四十條規定，體脂計應申請核准發給醫療器材許可證後，始得製造或輸入。若沒有許可證字號，表示未經衛生署審查及核准，不是合法的商品，對消費者缺乏保障。以有醫療器材許可證字號，通常是「衛署醫器製字第○○○○○○號」或「衛署醫器輸字第○○○○○○號」的合法體脂計為優先考量。

2. 體脂計的測量數據，與內建晶片的計算公式有關

若廠商是以外國人種（非台灣人）進行大量測量數據，再建立計算公式在晶片中，其量測數值就未必適用在台灣人身上，由於公式也是由大量的測試所推導出來的，因此任何一個體脂計都無法完全符合每個人的情形，所以建議選擇推導公式是以台灣人為基準的數據，較具參考價值。

3. 標準判定顯示

使用體脂計量測體脂時，最擔心數值的呈現無法立即判定標準與否，若將判定數據內建於體脂計上，每次量測完即可得知相關標準、偏高或偏低的判定，省去消費者量完還要去查詢數值判定的意義，更有利於消費者使用。

4. 記憶設定

一般體脂率會受到「身高」「年齡」「性別」三個變數影響，所以量測前要先調整這三個數值。使用體脂計測量體脂時，亦要先輸入這三項基本資料，才能測出體脂。但是每次量測都要輸入資料太麻煩，建議使用具有記憶功能的體脂計，只要輸入一次，下次量測時，就能直接使用囉。

手握式的量測迴路為身體胸部以上，站立式的體脂計則以腰部以下為迴路量測，由於肥胖者的脂肪多囤積於腰腹部及大腿處，故站立式的量測數字較為精準，手握式的體脂計誤差值較大。

進行量測前，請將產品放置於平坦地面上，避免在高低不平的地面或地毯/地墊等柔軟材質上使用，以免造成量測數值不準確。

海外配送皆採用「7-11 跨境物流服務」，運費由買方自行付費(以重量計算)會加至訂單金額，下表運費以台幣計價。

O'care App 操作

如何安裝O'Care？又該怎麼註冊呢?請看我們準備的教學小影片～

安裝完成後，要怎麼開始量測體重?App介面又該怎麼使用?

• 如何將量測數值與Health或Google Fit做串接?

• 如何在同一支手機內，新增多位使用者?

• 如何完整解除安裝，並重新安裝O'Care

請將手機的作業系統更新至 iOS 9、Android 4.3 以上版本，以改善此問題。

1. 確認app是否設定性別、年齡、身高等基本資料
2. 到手機的 「設定」>「藍牙」> 把所有配對的裝置移除，並重新開啟藍牙。
3. 把手機背景運作中過多的APP關閉掉一些，過多的應用程式開啟有機率產生錯誤狀況。
4. 若您產品使用了超過半年以上，有可能因為電量不足而產生異常，請換新電池再嘗試看看。
5. Android 系統 6.0 版本以上，需將手機快捷選單滑下，並開啟GPS功能。
