Calibrate Speed

You can calibrate the speed sensor to compensate for inaccuracies. Before
you change the setting, first calculate the percentage that the speed is off.
A good way to gauge your speed sensor's performance is to compare its
reading with the ground speed measured by your unit's GPS functions.
When you make a run to compare the GPS ground speed to the speed
sensor, perform your test in relatively current-free calm water, if possible.
(Unless, of course, you are taking the current speed into consideration when
making your calculation.)
For example, if you figure the sensor is reading 1 percent faster than
actual speed, you will enter – 10 in the calibration window. If the sensor is
reading 5 percent slower than true speed, you will enter + 5 in the window.
After you have a correct figure, here's how to enter it:
1. Press |
MENU
2. Enter the number you calculated earlier: press ↑ or ↓ to change the
first character (+ or –), then press → to move the cursor to the next
number and repeat until the percentage is correct, then press
blank, alarm is off.
