Photograph of T-3SIMULTANEOUSLY CHECK:

red bullet point Wide Frequency Range
20 KHz to over 500 KHz. Covers most all piezoelectric marine transducers.
red bullet point Temperature Sensor Test
Temperature of thermistor is read directly. No more guessing if the readout or transducer is bad.
red bullet point Speed Pickup Test
Indicator flashes when the speed paddle wheel is rotated for a positive check of the speed sensor.
red bullet point Leakage Indicators
Indicator lights if transducer fails leakage test.
red bullet point Resonance indicator Light Bar
Eight LED's indicate transducer's activity.

How it Works
The T-3 sends a swept-frequency signal to the transducer. The current to the attached transducer is monitored and compared to the internally generated signal in the T-3. When the transducer element vibrates at a resonant point, a phase change occurs. This is detected and lights one of eight indicators, depending on the frequency. If none of the indicators light, the transducer is bad.


Using the T-3
Connect a multi-sensor transducer to the 8-pin connector. Turn the power on, rotate the RES knob, and check for proper transducer activity. A leakage test is automatically done, lighting an indicator if water has penetrated the transducer or wiring. Temperature data from the transducer's thermistor is accurately read by rotating the TEMP knob to the point where the indicator LED changes color. A speed indicator flashes when the paddle wheel is rotated. Both Hall effect and reed switches are tested correctly. Quickly test multi-sensor transducers with one simple instrument on the spot, and determine if the trouble is in the display or transducer. Standard transducers are easily checked for resonance and leakage using the XDCR jack.

Test cable (for XDCR jack) and battery included!
