We strictly recommend using the adapter supplied with the device. If the adapter is broken or damaged, please contact our local service provider to purchase a replacement. Usage of another adapter is not covered under the warranty, and any subsequent damage will not be covered.

Plug type and voltage differs by country, and using the inappropriate adapter may result in device damage. Therefore, we recommend contacting your local service provider for more information, and to purchase the proper adapter.

All Charder accessories are designed specifically for use with Charder Medical devices only. The use of Charder accessories with devices produced by other brands may result in damage to the accessory and/or device.

We recommend using alcohol-based wipes to clean our devices. 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.

Once an AC adapter is connected, the device automatically stops using batteries, and switches to power supplied by the adapter.

Charder Medical scales do not require routine maintenance from the user, beyond regular cleaning using alcohol-based wipes for hygiene purposes. However, accuracy should be regularly checked and re-calibrated if necessary. Frequency of inspection is dependent upon the level of use and state of the device. If results are inaccurate, re-calibration is required - please contact your local Charder Medical service provider.

BMI is a basic index of weight-to-height commonly used to classify underweight, overweight, and obesity in adults. The definition of "normal range" differs according to gender, age, and ethnicity, as different populations may have different associations between BMI and health risks.

Though BMI does not actually measure body fat, it is often used to estimate if a person is at risk for obesity-related diseases. Due to its ease of measurement and calculation, it is the most widely used diagnostic tool to identify weight problems within a population. The chart below is the classification of weight for adults over 18 years on the basis of Body Mass Index according to WHO, 2000 EK IV and WHO 2004 (WHO - World Health Organization).

Note: BMI is calculated purely based height on weight, and does not distinguish between muscle and fat. As such, it can be potentially misleading, particularly for individuals with higher levels of muscle mass.
