YSI 600DW-B Sonde - Manual (Page 280)

Using Your DW Sonde with a 6500 Process Monitor Appendix G
Detailed instructions for the following operations are provided in the noted sections of the manual which
you received with your 6500 Process Monitor:
• Supplying power to the 6500 (Section 2.5.2)
• Connecting the sonde to the 6500 (Section 2.5.1)
• Configuring the 4-20 mA current loops to the existing sensors (Section 3.3.4)
• Interfacing the current loop or modbus output of the sonde to your SCADA system (Section 2.5.3)
• Using the 6500 software to set up your sonde, calibrate sensors, and customize the display
(Section 3.2)
This appendix to the Drinking Water Sondes Manual is designed as a “Quick Start” guide to common
operations involved in using your DW sonde with a 6500 and is also designed to be used as a “check list”
for this application. In addition, this appendix explains in detail the “Sample and Hold” feature of the DW
sonde software which has been designed specifically for applications in which the DW sonde is interfaced
to a 6500. Please refer to the following schematic diagram for many of the operations described below:

Select a Location for the Drinking Water Sonde and the 6500 Process Monitor. The sonde should be
located as close as possible to a water tap and a drain to minimize the tubing required. The 6500 should
also be located as close as possible to the sonde to minimize cable cost and must be within 250 feet (75 m)
in order to assure proper communication between the sonde and the 6500.
