GRAPH MODE
Selects the display starting position of the net sonde water temperature graph. SURFACE is the
first-water temperature (surface condition); BOTTOM the last-written water temperature (net
sonde position). The display range is 12
° C and scale interval is 5 ° C. For example, if the surface
water temperature is 18 ° C, the first temperature scale would be 10 ° C-20 ° C and the display
range is 9 ° C-21 ° C. If the water temperature drops by 9 ° C, for example, the next temperature
scale would be 0 ° C to 10 ° C and the display range –1 ° C to 11 ° C.
