Correcting the Temperature Reading
The temperature sensor of this watch is adjusted at the factory and so further
adjustment is not required by you. However, if you notice that the readings
produced by the watch are different from readings produced by another instrument,
you can use the procedure in this section to make corrections. You also can use
this procedure to clear a correction.
Important!
•
The watch will not be able to produce correct temperature readings if you make a
mistake during the correction procedure. Check to make sure that the value you
use for correction produces correct temperature readings.
•
Before performing the following procedure, remove the watch from your wrist and
leave it for about 20 or 30 minutes to allow the case temperature to become the
same as the air temperature.
