OBS-3A Turbidity and Temperature Monitoring System

Change to RS-232

To switch from RS-485 communication to RS-232 communication, press the

RS-232 button and then remove the RS-485 converter.

Once the button is pressed, you will no longer be able to

communicate via RS-485. However, if you accidently push this

button, the OBS-3A can be reset by removing and reinserting the

batteries.

NOTE

Coefficients

The Coefficients box can be used to retrieve and save the coefficients stored in

the OBS-3A that are used to calculate the output values for each sensor. The

saved files can be used to load the coefficients into the OBS-3A at a time later,

if necessary.

Press the Retrieve and Save Coefficients to File button to retrieve the

coefficients from the OBS-3A and save them to a file on your computer.

Select the desired sensor from the resulting dialog box and then press the Save

Coefficents to File button. It is a good idea to save the coefficients for each

sensor to a file.
