To simplify operation, the “sensor installed” options can be set
to “No” to remove all references to temperature and speed
from all the screens.
Highlight the appropriate line and press EDIT to change an
option.
Speed calibration is entered as a percentage from –99% to
+99% to make the speed read lower or higher than the
uncalibrated value.
NOTE:
You must enable the speed setting under the Data menu on the
ECHO SOUNDER screen; see ”Setting the ECHO screen data”
starting on page 5-44..
Temperature is calibrated by entering the temperature error as
a number of degrees from –99 to +99. This offset is added to
the uncalibrated temperatures before they are displayed or
graphed.
