  • Page 15: Introduction

    This manual covers the generic aspects of altimeters and shows the specifications for the standard setup with the Tritech International Ltd 6 pin connector. There are a wide range of different configurations available for Tritech altimeters so it is important to use this manual in conjunction with the original purchase order which should detail the exact configuration of the product in hand.

    The axes for the AHRS within the echosounder are shown below. 3.3.3. Mounting The mounting point on the Dual Frequency Altimeter utilises as 1⅛"-14 BSW (Whitworth) thread. This interface is shared with the mounting system for the Tritech MicronNav and Gemini products. Tritech adapters are listed below: 0286-SOM-00001, Issue: 09 ©...

If the altimeter has been set to interrogate mode it will not output data until the interrogate command (Z) is received, at which point a single data string is transmitted to the surface computer.

    4.5. AltTest Software General Guidelines The AltTest program available from Tritech provides a simple way of communication with Tritech altimeters and displaying the data. It is compatible with Microsoft Windows. Altimeter data can be logged in a raw or processed format and the processed data can be imported into a spreadsheet package for post-processing.

  • Page 35: Maintenance

    Note Alternative configurations may have additional serviceable items, if in doubt please contact Tritech International Ltd to establish the correct service routine. The o-ring seals should be regularly inspected, cleaned and lubricated with the appropriate greasing compound. The body of the unit should also be inspected for any obvious signs of corrosion, especially in mating surfaces (such as the waterblock).

  • Page 36: Ordering Parts

    Since there are a vast amount of different configurations of altimeters the simplest way to do this is to contact Tritech International Ltd providing the serial numbers off the unit body. Serial numbers are either located on the silver label affixed to the body tube or if this has been damaged the embossed numbers on the transducer endcap, body tube and connector endcap can be used instead.

  • Page 37: Disassembly Of The Altimeter

    The threads of the altimeter should be made up and broken out by hand, or by using light pressure on a strap wrench. The application of additional force may indicate and result in damage to the unit. 0286-SOM-00001, Issue: 09 © Tritech International Ltd.
