The Model 106 is an impeller-based meter measuring speed and direction, with optional temperature and depth parameters. As standard, they are Self-Recording only instruments, but a Direct Reading capability can be fitted as an option. All units can be operated directly via PC; alternatively the Model 8008 Control Display Unit can be used for controlling Direct Reading operation:
• Self Recording Mode: Sample setup and data extraction can be carried out using deck lead from PC to internal 9 Way D-type connector. It is not possible to control or read data from a Self-Recording only unit whilst it is deployed.
• Direct Reading Mode: Over short cable lengths ( up to 50m) RS232 communications are possible via the external 4 Way Mil-Spec connector and PC. Over longer cable lengths, communications are via Digital Current Loop. The 8008 CDU has an integral current loop adapter, so direct use of the instruments with this unit is possible. If it is required to use the meters with a PC over long cable lengths, a separate Digital Current Loop Adapter will be required.
Power to the Model106 may be taken from their internal battery, from the 8008 CDU ( if used) or from a surface battery or power supply. When power is taken from the internal battery ( 1.5V alkaline D cell) , battery life is approximately 30 days at 10 second sampling rate, or 56 days at 5-minute sample rate. Using a 3.6V Lithium D cell, life is approximately 90 days at 10-second sample rate, or 180 days at 5-minute sample rate.
