Analog Input Volume Modulation - YSI ProSample Series User Manual

Analog Input Volume Modulation

In this type of program, the ProSample will begin collecting samples when a 4-20 mA device (e.g. YSI Amazon Bubbler
or YSI IQSN sensor) meet user-defined sampling criteria. The amount of sample collected depends upon the 4-20 mA
signal.
All ProSample models can be used for this sampling scenario. A flow signal cable (item # 630147) must be connected
to the analog device and the ProSample. As is shown in the
and white wires should be used when connecting the flow signal cable to the analog device.
NOTE: The settings modified in the section
and every program, so it is important these settings are carefully set before starting any program.
NOTE: Screenshots demonstrate an example setup. Settings should be adjusted for your specific application.
NOTE: The analog signal should be calibrated before running an analog program. See
Signal on page 25.

Configure Key Instrument Settings
1. From the Main Menu, select Programs g Change. Choose the
program you would like to modify by using the left and right
arrow keys. In this example, we will modify Program # 1. Press
the Enter key to begin modifying the program.
2. Highlight Variable Time and press the enter key.
3. Var Unit is displayed. This ultimately does not impact the
measurement result, but a unit does need to be used. In this
example, l/s will be used as the 'dummy' unit. After highlighting
a unit, press the Enter key.
4. Var Set Flow at 20 mA is displayed. Although the value
entered here ultimately does not impact the measurement
result, it can be used to document the measurement value (e.g.
flow) that corresponds to a mA signal of 20 mA. After entering a
value, press the Enter key.
