YSI 6500 Environmental Process

Monitor

The YSI 6500 monitor combined with the YSI 6-series multi pa-

rameter sondes is intended for use in water quality monitoring ap-

plications. The sondes are able to measure up to 15 different pa-

rameters. The sensors are all located in the submersible sonde that

also contains signal circuitry and communications circuitry that

transmit sensor readings via SDI-12 protocol to the 6500.

For installing the monitor more than 25’ and up to 250’ from the

sonde, use an optional YSI breakout box and patch cable with user-

supplied wire. For using the monitor with more than one sonde, use

the YSI # 6508 Junction Box. See Appendix D of the 6500 Opera-

tions Manual for installation details.

FIELD OPERATION GUIDE YSI 6500 Environmental Process Monitor The YSI 6500 monitor combined with the YSI 6-series multi parameter sondes is intended for use in water quality monitoring applications. The sondes are able to measure up to 15 different parameters. The sensors are all located in the submersible sonde that also contains signal circuitry and communications circuitry that transmit sensor readings via SDI-12 protocol to the 6500.

INITIAL SETUP Once the 6500 Environmental Process Monitoring system is installed and properly powered, use the 7 keys on the 6500 to set up your system. The 6500 powers up to Run mode (readings displayed). If necessary, adjust contrast by pressing and holding the Cal key while using the up/down arrow keys. To begin setup press Esc and Enter keys simultaneously for one second to view the Main menu display. To move backward one level in the menu press Esc.

CALIBRATION OPTIONS There are several approaches to calibrating the sonde sensors for use with the 6500 Monitor. Options 1-3 all depend on an installation where convenient disconnection and removal of the sonde is desirable. See Section 4 of the 6500 Operations Manual for detailed calibration instructions. Options 2 and 4 are described in this guide. 1. Remove the sonde from the deployment site and Sonde to Lab Computer DB-9 Power Supply 6037: 220 VAC 6038: 110 VAC 6095B Adapter MS-8 You will need...

FIELD CALIBRATION Below are instructions for calibrating the sonde sensors using the 6500 monitor. If the monitor is mounted outside and the air temperature is below freezing, take care not to expose the sensors for prolonged periods during calibration. Below is a list of supplies you will need to take to the deployment site. Also, you need to know the local barometric pressure for DO calibration. ! ! ! ! ! ! Bucket of clean water to rinse sonde body between cals.

A live display of pH appears. With the highlight on Cal, press Enter to confirm the calibration. A message will appear confirming the calibration and displaying the new value (e.g., 7.00). If you choose to abort or redo calibration for any reason, highlight the appropriate choice above. Remove the sonde from the pH 7 standard. Rinse with water; shake excess water from sonde body. Continue to the next standard (e.g., pH 10), pre-rinsing in used standard if possible.
PAGE 6
SET AND CHECK RELAYS AND 4-20 CURRENT LOOPS There are 4 relays resident in the 6500 for which parameter limits may be set. From Main menu highlight Relays and press Enter. Choose Configure Relays in the next screen to display the Relay, set, hys menu shown to the left. For each of the 4 relays press Enter to activate the next display which allows you to assign parameter, condition and set point. Note, hysteresis (hys) or “dead band” allows you to manage relay “chatter” at the set point.
PAGE 7
IN SITU CALIBRATION As described on page 3, you may perform a one-point calibration of each of the parameters (except temperature). By this method leave the sonde deployed and use a portable meter to perform a spot measurement that is representative of the sample stream, then adjust the 6500 display to read the same value. In the example below, DO mg/L is described. From Main menu, highlights Calibration setup then press Enter to access the assigned parameters.
