What is Automatic Shift Function ?
This is a function that is activated when operating the Thermometer.
How does it work ?
If you have switched the temperature measurement frequency from every minute to every second – described in How to use Digital Modes – and left the watch then : per-second measurement mode will be automatically shifted to per-minute measurement mode in 4-5 minutes.
Why was this feature invented ?
You’re probably wondering why the manufacturer came up with this function, since measuring every second sometimes seems more practical than measuring every minute ?
Well, this function has been programmed into the microprocessor structure in order to save energy !
It turns out that measuring temperature activates additional processes in the chip, which causes a slightly higher power consumption. Similarly to how modern computers heat up when they perform more calculations.
This slightly higher power consumption – in the range of even microwatts (millionths of a watt) when multiplied many times will give us a quite significant difference.
With the factory-set temperature measurement, i.e. every minute, we have 60 minutes x 24 hours = 1440 measurements per day.
If we wanted to constantly measure temperature every second, we would have to multiply this result by 60 more times because the watch would additionally perform 60 measurements per minute.
We would therefore have 60 seconds x 60 minutes x 24 hours = 86400 measurements per day. Now we can clearly see the difference in power consumption in the temperature measurement mode every minute and every second in just one day.
Ratio 1440 to 84600, do you see the difference now ?
