Speed Calibrate
If the transducer is equipped with a speed paddlewheel, the DS400/500
calculates the speed of the boat through the water. The Speed Calibrate
option enables you to adjust the displayed speed so that it matches your actual
speed through the water. You can adjust the displayed speed from 1% to
200%.
If the sounder reading is too low, set Speed Calibration to more than 100%. If
the sounder reading is too high, set Speed Calibration to less than 100%. This
setting also calibrates the Log, Trip and paddlewheel distance.
Temp Calibrate
If the transducer is equipped with a thermistor, the DS400/500 calculates the
temperature of the water. The temperature calibrate option enables you to
adjust the displayed temperature.in 0.1 degree increments of the temperature
units you have assigned using the UNITS... parameter. (See page 71.)
Sounder Simulator
The simulator enables you to operate your display without data from the
transducer, in order to become familiar with the sounder features and
functions. You can set the simulator ON or OFF. You cannot select OFF when
the unit is powered on without a transducer connected.
