Manual – Starflow QSD Model 6527B and 6537A
The next section deals with the SDI-12 address of the QSD Instrument. This is a number between 0-9
and gives the instrument a unique SDI-12 address, in case there is more than one SDI-12 instrument
on the common SDI-12 address.
The setting associated with the Ultrasonic depth sensor is shown above. When this option is ticked
the QSD will return 0mm for any depth below its minimum operating depth. This minimum operating
depth is currently 45mm so any depth below this with the check box ticked will give a depth reading
of 0mm.
