Quick start

Connect the T3D to a piezoelectric transducer and turn it on by pressing the power button. The

bar graph will show one or more illuminated sections corresponding to the resonant points of the

transducer. If no lights come on, the transducer element is bad. The T3D will turn off after two

minutes of operation. It can also be turned off by pressing both the function and -sensitivity

buttons.

Other tests

Multifunction transducers may be tested for correct operation of the thermistor and the speed

paddle wheel by connecting them to the 8-pin multi-function connector. The 8-pin connector

wiring is configured for the most popular multi-function transducers and is detailed at the end of

this manual.

Leakage

The leakage test is activated by holding the function button down until the segment next to leak

flashes. An open circuit (> 10 meg ohms) will cause all segments to light. A short (<10 ohms)

will light only the segment next to 0.

Temperature

Again press and hold the function button until the segment next to temp blinks. The first digit of

the temperature is indicated by the flashing segment and the second digit by a steady segment.

The readout is in degrees centigrade unless the E F button is held down for a Fahrenheit reading.

Front panel controls and connectors

Power:

Turns the T3D on.

Function:

Selects various modes of operation when

held down. Also used to initiate calibration

sequence.

Sensitivity -: Reduces the sensitivity to the transducer'

resonant points. Also used with Function

button to turn unit off.

Sensitivity +: Increases the sensitivity to the transducer'

resonant points. Additionally used to

display temperature in degrees Fahrenheit

when in the temperature test mode.

Multi-function:

Used to test transducers with combined

depth-temperature-speed functions.

Standard:

Use to connect to piezoelectric transducers

in the 50 to 500 kHz range.
