How to set personal data on the ECG OV 125 scale?

Press and hold the SET button after turning on the scale. Use the +/- buttons to select the user number (1 to 12), then press SET to confirm. Then set height, gender, and age in the same way. Once done, tap the platform to save.

How to measure body fat percentage?

After setting your parameters, step barefoot onto the scale ensuring your feet touch the metal electrodes. The scale will successively display weight, body fat percentage, water, muscle mass, bone mass, and calories.

Why do body composition results vary?

Variations may be due to time of day, hydration, recent physical activity, or temperature. Always weigh yourself under the same conditions for better reliability.

What to do if the screen displays 'Err' or 'C'?

If 'C' appears after weighing, an error occurred. Repeat the measurement. If the screen remains abnormal, remove the batteries for 3 seconds then reinsert them. Contact the retailer if the problem persists.

Does the scale come with batteries included?

No, batteries are not included. You need to insert 2 AAA 1.5 V batteries respecting polarity.

Adding weight

The weighed object must weigh more than 2 kg. If you want to find e.g. the weight of your baby, weigh yourself first (wait until the numbers stabilize), then without stepping off the scale, take the baby in your arms. The numbers start flashing, then they stabilize and the resulting weight stabilizes. Subtracting your own weight from the newly obtained value will give you the weight of your child.

Measurement of body fat, water, muscle mass, bones and calories

Measurement principles

Through human body pass electric signals of a certain frequency, whereby the impedance of body fat is higher than the impedance of muscle or other human tissues. The device generates an alternating electrical current with safe frequency and low voltage. Using the analysis of biological resistance, impeding the passage of the current through the human body (impedance of various tissues, fats and muscles), the percentage of the body fat in human organism is derived from the differences in resistance.

About the percentage of body fat

This index is an indicator of the percentage of body fat in the human body.

The fat content in the body should be maintained around certain level, excess body fat impairs metabolic processes and thus increases the risk of various diseases.

Note: The values stated in this table are merely for orientation purposes.

(1) Setting personal data

1. After you insert the battery and turn it on the first time, the default parameters are set to following values:

Memory Sex Height		Age
1	Male	165 cm	25

1. Parameters can be set within the following range:

Memory	Sex	Height	Age
1 ~ 12	Male/Female	100 ~ 250 cm	10 ~ 100

1. Setting parameters

Example: User no. 3, a woman, 168 cm, 28 years can set her personal data as follows:

graph TD
    A["Press the weighing surface to turn the scale on."] --> B["Press and hold SET"]
    B --> C["165 cm"]
    C --> D["The user number is fl ashing"]
    D --> E["Press"]
    E --> F["select the user number"]
    F --> G["165 cm"]
    G --> H["Press SET"]
    H --> I["Confir rm and continue to next setting"]
    I --> J["165 cm"]
    J --> K["Height data is fl ashing"]
    K --> L["Press SET"]
    L --> M["Confir rm and continue to next setting"]
    M --> N["168 cm"]
    N --> O["Press SET"]
    O --> P["User age is fl ashing"]
    P --> Q["Press"]
    Q --> R["select sex"]
    R --> S["165 cm"]
    S --> T["Sex symbol is fl ashing"]
    T --> U["Press SET"]
    U --> V["168 cm"]
    V --> W["Turned off scale"]
    W --> X["Automatic turn off after a few seconds"]
    X --> Y["0.0 kg of the user number stops fl ashing and "0.0" appears."]
    Y --> Z["Tap on the weighing surface and wait several seconds."]
    Z --> AA["Press SET"]
    AA --> AB["168 cm"]
    AB --> AC["The user number starts fl ashing again. By repeating the procedure, you can set another user or by tap on the weighing surface stop settings and save user parameters into memory."]

Note:

• When you interrupt entering data for a few seconds, the already specified parameters are automatically stored in memory and the display shows "0", which means that you can start measuring body fat content.
• If during the parameters input the display shows "0", you can press and hold SET to return to the personal data setting mode and enter the user number, sex, height and age.

(2) measuring the physical data

Turn the scale on by briefly pressing on it, then press and hold the button SET and using the arrows select the user number. After a short while, when the user number stops flashing, step on the scale. (Make sure that the feet touch the metal electrodes on the weighing surface. Otherwise, it will not be possible to measure the body fat.) To ensure accuracy, remove shoes and socks before stepping on the scale.

Example: User no. 3, female, 168 cm, 28 years can measure herself as follows:

graph TD
    A["Turned off scale"] --> B["Turn on the scale by stepping on it shortly."]
    B --> C["The parameters of last user or default parameters will be displayed."]
    C --> D["Press"]
    D --> E["Select a user number or set parameters"]
    E --> F["168 cm"]
    F --> G["Tap on the weighing surface"]
    G --> H["LCD displays "0.0""]
    H --> I["Gently step on the scale (Both feet are touching the metal electrodes)"]
    I --> J["Wait until the numbers stabilize"]
    J --> K["The locked weight fl ashes"]
    K --> L["Measuring..."]
    L --> M["Measurement results will be displayed and the measured values will be saved in memory for later comparison. The data on the display repeat in cycles: Weight: 52,8 kg, Bar graph of fat, Fat proportion 23,8 %, Water proportion 52,3 %, Muscle mass proportion 37,2%, Bones proportion 12%, Calories 1840."]

Notes on the calories

Calorie is an energy unit.

Calories and energy use

The displayed value indicates the energy you need according to your weight, height, age and sex to maintain everyday metabolism and ensure normal activities.

Calories and weight loss

Calories intake control combined with appropriate exercise is an effective method for losing weight. The principle is very simple. Once daily energy intake is insufficient to meet energy expenditure of the organism, the stored sugars and fats start to break down to make their burning cover the energy consumption of the organism. The resulting effect is weight loss.
