HI 83414 automatically selects the correct turbidity
range to display the results with the highest
accuracy. If the measured value is higher than
4000 NTU (980 EBC or 26800 Nephelos), the
display will show the maximum value blinking
and the message “
Out of range” on the message
line.
UNITS CHANGE
To change the units, simply press the Unit key when a measurement is available. The Nephelos
value is obtained by multiply with 6.7 the NTU value. The EBC value is obtained by multiply with
0.245 the NTU value.
