The measured values can be recorded once per day or twice per day (AM and PM). They are shown in the form of graphs as a function of time. Time is indicated along the horizontal axis. The unit of time is date. Todays date is on the far right of the axis. The measured values are given along the vertical axis.
The latest recorded value can be changed if the change is made within the same day when recording once per day, or within the same AM or PM when recording twice per day.
The measurement values can be shown at each data point.
The date window of the horizontal axis can be changed. It is set in number of weeks. This date window can be moved back in time by scrolling the graphs if you wish to study earlier measurements.
The temperature can be recorded in degrees Celsius (°C) or in degrees Fahrenheit (°F). Changing between °C and °F is done by tapping the °C or °F button.
In the same way, the weight can be recorded in kilograms (kg) or in pounds (lb). Changing between kg and lb is done by tapping the kg or lb button.
Weight varies greatly from person to person. If the weight scale were to be fixed, it would have to cover a wide range. It would give a poor opportunity to show small changes in weight. Therefore, the weight charts use a much smaller range of just a few kilograms or pounds. The position of the range is determined by the first weight recorded. The range is afterwards automatically adjusted so that all values within the date window are shown. This allows you to more clearly see how the weight varies.
The weight can be recorded with up to three decimal places, i.e. with the resolution 1 gram. This can be suitable if you want to register small weights.
The measured values are stored in files in the devices document folder. They are text files that can be exported to other programs for further processing if desired.
