Introduction
This document covers the installation and operation of Model 106 Self-Recording/Direct Reading Current
Meter, when used with the 8008 Control Display Unit.
It also covers general maintenance procedures, and the calibration data of the units. Operation of the Meters
with Windows PC software is covered in the supplementary DataLog x2 software manual.
1.1.
General Description
The Model 106 is an impeller-based meter measuring speed and direction, with optional temperature and
depth parameters.
The 106 can be operated in a self-recording mode, or be operated in direct reading mode via a PC.
Alternatively the Model 8008 Control Display Unit can be used for controlling Direct Reading operation:
1.1.1.
Self-Recording Mode
Instrument setup and data extraction can be carried out using the supplied Y lead from PC to external 10 way
SubConn connector.
1.1.2.
Direct Reading Mode
Over short cable lengths (up to 100m) RS232 communications are possible via the external 10 Way SubConn
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 Model 106 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.
The 106 is fitted with a 512K memory. This equates to storage of over 131000 speed and direction records
(over 65000 if temperature and depth are also fitted) provided the data is stored in a single file.
The CDU is fitted with a 128K memory. This equates to storage of over 32000 speed and direction records
(over 10000 if temperature and depth are also fitted).
Both 106 and CDU have a limit of 100 files.
1.1.3.
Configuration and Data Download
The 106 is supplied with DataLog x2 software for setup and data offload and display with a number of
alphanumeric and graphical options.
