Analog Out Setup
Voltage
Range
Select the voltage range for analog outputs. Either 0
–5 volts or
0-10 volts.
lin/log
Select whether the channel will display the analog voltage response
linearly proportional to concentration (lin) or with a logarithmic (Log)
response characteristic.

Select whether the channel will display the analog voltage response
“normalized” dN/dLog(Dp) or non-normalized (dN) over the
selected particle size range. dLog(Dp) = Log(MaxConc)
–
Log(MinConc).
Min/Max Dp
Spin Control but values can be entered manually. The Maximum
Value is 562.300, minimum is 5.624.
Power Dn
The Maximum Value is 10, minimum is 0.0000.
