I n t r o d u c t i o n

Thank you for purchasing the YSI Professional Optical Dissolved Oxygen (Pro ODO) instrument. The YSI ProODO™ measures dissolved oxygen in water using T h i s p a g e l e f t i n t e n t i o n a l l y b l a n k lifetime luminescence technology and uses a digital signal to send information between the instrument and probe. Key advantages of the new ProODO include the elimination of sensor flow dependence and sensor warm-up time, greater stability, the ability to zero the sensor for more accurate measurements at low dissolved oxygen levels, and the elimination of frequent membrane/electrolyte changes. The ProODO also features a waterproof (IP-67) case, a rugged MS-8 cable connector, backlit display and keypad, user-selectable cable lengths, USB connectivity, large memory with extensive site list capabilities, and a rugged, rubber over-molded case. For product specification information, please visit www.ysi.com or contact Technical Support at 800-897-4151 ([phone]).

Reading the entire manual before use is recommended for an overall understanding of the instrument’s features.

G e t t i n g S t a r t e d

Initial Inspection

Carefully unpack the instrument and accessories and inspect for damage. Compare received parts with items on the packing list. If any parts or materials are damaged or missing, contact YSI Customer Service at 800-897-4151 ([phone]) or the authorized YSI distributor from whom the instrument was purchased.

Battery Installation

The ProODO uses 2 alkaline C-cell batteries. Battery life depends on sampling mode and usage. When used in Manual Sampling mode, under normal conditions, battery life is approximately 80 hours at room temperature. The use of Automatic Sampling mode may slightly reduce the battery life. See the System section of this manual for more information on Sampling Modes.

Initial Setup

Throughout the manual, the term “probe” refers to the end of the cable where the sensor is located, the term “sensor” refers to the Optical Dissolved Oxygen sensing portion of the cable/probe assembly, and the term “sensor cap” refers to the removable sensing cap that is replaced about once per year (Figure 3).

Figure 3

Unpacking the ODO Probe

Each ProODO cable/probe assembly and replacement ODO

isensor cap includes an instruction sheet with important information unique and specific to each individual sensing cap.

Remove the cable/probe assembly from the shipping container and locate the instruction sheet included with your assembly. This instruction sheet is important because it includes the calibration coefficients for your sensor cap. After using this sheet for general probe setup, be sure to store it in a safe place in case you need to reload these calibration coefficients in the unlikely event that they are ever deleted from the probe.

Note - A new cable/probe assembly already has a

isensor cap installed and the sensor cap coefficients are preloaded into the probe at the factory.

Preparing the probe for the first time:

1.Remove the metal probe guard from the probe by turning it counterclockwise.

2.Remove the red storage cap which contains a moist sponge from the end of the probe by pulling it straight off the sensor. Save this to use later for long term storage.

3.Reinstall the probe guard by sliding it carefully over the sensor and then threading it onto the cable/probe assembly with a clockwise rotation (Figure 4).

4.Locate the grey calibration/storage sleeve that was shipped with your probe/ cable assembly. Moisten the sponge in the grey calibration/storage with a small amount of clean water.

5.Slide the calibration/storage sleeve over the probe guard to keep the probe in a moist atmosphere for storage or calibration (Figure 5). It is important to always keep your sensor in a moist environment so the sensor cap does not dry out. (See Care, Maintenance, and Storage for more information.)

Connecting the Probe/Cable Assembly to the Instrument

To connect the cable, align the keys on the cable connector to the slots on the instrument connector. Push together firmly, then twist the outer ring until it locks into place (Figure 6). This MS-8 (Military Spec) connection is waterproof.

Figure 6. Note the keyed connector. The cable and instrument connectors can only be mated once the keyed sections are properly aligned. When disconnected, the cable connector and the connector on the instrument maintain an IP-67 rating.

Main Display

Press and hold the Power key for two seconds to turn the instrument on. The instrument will briefly display two splash screens then go directly to the main run mode screen. The first time the instrument is powered up, you will need to set the date and time. Follow the instructions under the Setup | System | Date/Time section of this manual.

The display at the left shows the run mode (main display) with temperature in °C, barometric pressure in mmHg, DO in % and mg/L as the reported parameters. The date, time and battery level are indicated at the bottom of the screen. The logging preference of Log One Sample at a time is indicated at the top of the screen.

This screen also shows the message line towards the bottom of the display above the date and time. In this case, it doesn’t show a message. However, messages will appear frequently to indicate successful calibrations, saved configuration changes, etc.

A USB symbol will show up on the bottom of the display when connected through USB with the communications saddle. The instrument will display full

battery power when it is receiving power through the USB connection.

Contrast – the contrast adjustment can be accomplished

iby repeatedly pressing the backlight key and the left or right arrow key at the same time.

Menu Layout

Press Esc	at anytime in the menus to escape back to the Run screen. The
left arrow	can be used to go back to the previous menu in all screens

except alpha/numeric entry screens. You must use Esc to get out of the alpha/ numeric screens if you want to exit before finishing or without saving changes. Functions that are enabled appear as a circle with a dot . Disabled functions

appear as a circle only . In addition, some options appear as an empty box P or a box with a check mark Q.

Alpha/Numeric Entry

The numeric screens will display numbers only (shown above, left). Alpha/ numeric screens will display numbers across the top and letters along the bottom rows (shown above, right). Letters appear as a common keyboard arrangement.

When an alpha or numeric character is required, the display will show the alpha/ numeric entry screen. To select a character, highlight it by using the arrows to move the highlight box over the desired selection. Then, press Enter on the keypad to confirm the selection. After confirming the selection, it will appear in the line at the top of the display.

For capital letters or lower case entry, highlight “SHIFT” and press Enter on the keypad to change the characters from upper to lower case.

To delete the entire line of the current entry, highlight )and press Enter on the

keypad. The !symbol functions as a backspace key in the alpha/numeric entry screens by deleting one character at a time. Use the “SPACE” function to add a space between characters.

When you have finished entering the correct information (16 character max), highlight <<<ENTER>>> at the bottom of the screen and press Enter on the keypad to confirm.

The	key cannot be used to escape to the previous menu from
i an alpha/numeric entry screen. Instead, use the		key to go

back to the previous menu when in alpha/numeric entry screens.

Time – highlight and press enter to use the numeric entry screen to set the correct time.

GLP

The GLP or ‘Good Laboratory Practice’ file saves detailed information about calibrations. It also includes diagnostic information about the sensors.

Calibrations are logged into a file, the GLP, for later review as needed. A single GLP file is utilized to store all calibration records and is capable of storing 500

records. Once the GLP file is full, the instrument will begin to overwrite the oldest record with each new calibration record.

In order to keep all of your GLP records, periodically download the GLP to Data Manager and export it to another program.

Otherwise, the instrument will overwrite the oldest record

ionce the memory is full. Also, since Data Manager saves GLP files under the Unit ID, you must periodically export and rename the GLP file on your PC or it will be overwritten each time you upload the GLP file from the instrument.

Several calibration parameters are saved for each calibration including optional ones that can be enabled by the user. Standard parameters include date/time stamp, calibration method, and sensor information. Optional, user selectable parameters include User ID, Probe ID, and User Fields 1 and 2.

In addition, there will be information specific to the Dissolved Oxygen or Barometer calibration record. A Dissolved Oxygen calibration record will contain the following calibration specific parameters:

DO

Sensor - Serial Number of the Sensor Calibration Method - Zero, %, or mg/L Cal Value

Sensor Value - Tangent of the angle between reference and signal LED, must be within 0.2 of the default value in the sensor, typically between

-0.53 and -2.17 Salinity Mode - Always manual

Salinity Value - Value entered by the user Barometer - Barometric Pressure during calibration Temperature - Temperature during calibration Calibrate Status - Calibrated

A Barometer calibration record will contain the following calibration specific parameters:

Barometer

Barometer - Calibrate value in kPa

Calibrate Status - Calibrated
