Making Precise Measurements; Calibrating The Stride Sensor; About The Stride Sensor - Epson SF-510 User Manual

Use either of the following methods to enter Indoor
mode.
O Press C or D to highlight Indoor during GPS
positioning, then press A.
O If GPS positioning fails, press C or D to highlight
Indoor on the screen displayed, then press A.

Making precise measurements

When you use the product for the first time or when
the product has not been used for several months, you
need to allow the product to completely synchronize
with the GPS satellites. Switch to the Measurement
screen, then wait outside for at least 15 minutes with no
obstructions overhead. Your product will track your
movements with greater accuracy after this extended
calibration.
You will not need to repeat this process again unless
you do not use the product for a few months.

Calibrating the stride sensor

About the stride sensor

This product has a built-in stride sensor. The stride sensor calculates distance and laps with high precision, and
measures your pitch and stride even when the GPS signal is lost.
Setting up your SF-510/SF-710
Note:
The basic configuration of the GPS system is 24 satellites
orbiting the Earth at an altitude of about 12,500 miles
(20,000 km), with at least four satellites travelling in six
different orbits. The GPS receiver acquires data from
four satellites and calculates the latitude, longitude,
altitude, and time. Measuring can start once positioning
has been performed and this information has been
received. Your product receives more detailed GPS
navigation data after 15 minutes of GPS positioning,
which allows you to make more precise measurements.
Errors may still occur in distance measurements due to
atmospheric conditions and your specific surroundings.
