4. System Operation
4.1. Setting Up
To prepare the system for use:
i.
Clean the probe electrodes to remove any grease or dirt.
ii.
Insert batteries [8 off 1.5v C type cells], if external power not being used. It is recommended
that alkaline type cells are used for maximum life.
iii.
Connect cables for particular combination of hardware being used.
iv.
If using with probe fixed to wading rods then assemble probe into adaptor [clamping using
the small grub screw] and fix to rods, base and direction knob assembly.
v.
If mounting the probe by other means, it should be noted that the mounting may affect the
flow characteristics and thus introduce an error into the measurement. Users can of course
adjust results by carrying out their own calibration.
Once the system has been connected up, it is ready for use. For testing purposes, all of the CDU
operations can be carried out without the sensor in water, but the real time data will be
meaningless.
