Press and hold the function switch until the segment next to speed lights. Rotate the speed paddle

wheel and the 0 and 1 segments will light indicating the state of the output signal. Spin the

paddle wheel rapidly and the bar graph lights progressively.

Battery test

When the T3D is first turned on, all bar graph segments flash briefly to test the segments,

followed by one segment. The position of this segment displays the battery voltage. If it

illuminates at 6 or lower, change the battery. Replace with an alkaline 9 volt battery similar to

EVER READY #522 or equivalent.

Calibration

To insure the best accuracy the T3D should be re-calibrated if the ambient temperature has

changed by 30 degrees Fahrenheit or more relative to the last calibration. To calibrate the unit

the power must be off and no transducer connected. With the unit in the power off condition,

press and hold the function button then press the power button. Do not release the function

button for three seconds. Successful calibration is indicated when all segments go out.
