ROX 10.0
Altitude points list
To prevent weather-induced changes of altitude, the device stores ‘altitude
measurement points’. every time the user calibrates the barometric altitude, the
RoX 10.0 gps stores the location. whenever the user returns to this location
(within a 30 m radius), the altitude is automatically calibrated.
The altitude measurement points from the IAC+ altitude calibration are stored in
the altitude points list (see ‘‘10.4 Altitude’’). you can also delete individual altitude
measurement points from this list.
CAUTION:
The air pressure at your weather station is the air pressure at the measurement
site and not the air pressure reduced to sea level! An opening below the
button on the RoX 10.0 gps is used to measure the air pressure. This opening
must not be covered. Do not insert sharp objects into the measurement hole!
5.3 Power calculation or measurement
Note
The RoX 10.0 gps can calculate (!) the power on the basis of several
parameters or use the power values sent via an ANT+ compatible power meter.
please choose between power meter and formula under settings/Device/
power meter or Formula.
5.3.1 Power calculation
The power is calculated (!) on the basis of the speed, cadence, incline, bike
weight, bike type, rider position, body weight, shoulder width and body height. The
wind speed is not considered.
The power can only be calculated in conjunction with the cadence.
The power values displayed are approximations and are calculated presuming an
average wind speed and average road conditions.
5.3.2 Power measurement
The RoX 10.0 gps is furthermore fully compatible with ANT + compatible power
meters (e.g. sRm power meter – www.srm.de). These power meters measure
the power using forces e.g. on the pedals and are therefore independent of
external influences.
