INTRODUCTION

Thank you for purchasing the YSI Pro2030, an instrument from the YSI Professional Series product family. The Pro2030 measures dissolved oxygen, conductivity and temperature in water. The Pro2030 features an impact resistant and waterproof (IP-67) case, a rugged MS-8 (military-spec) cable connector, backlit display, user-selectable sensor options, 50 data set memory, internal barometer and a rubber over-mold case.

The Pro2030 provides valuable instructions and prompts near the bottom of the display that will guide you through operation and use. However, reading the entire manual is recommended for a better understanding of the instrument’s features.

The Pro2030 cannot communicate to a PC via a Pro Series

communications saddle. Connecting the Pro2030 to a communication saddle may cause erratic instrument behavior.

GETTING STARTED

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 (+1 937 767-7241) or the authorized YSI distributor from whom the instrument was purchased.

BATTERY INSTALLATION

The instrument requires 2 alkaline C-cell batteries. Under normal conditions, the average battery life is 425 hours at room temperature without using the back

light. A battery symbol will blink in the lower, left corner of the display to indicate low batteries when approximately 1 hour of battery life remains.

To install or replace the batteries:

Turn the instrument off and flip over to view the battery cover on the 1. back. Unscrew the four captive battery cover screws. 2. Remove the battery cover and remove the old batteries if necessary. 3. Install the new batteries, ensuring correct polarity alignment (figure 4.

1).

Place the battery cover on the back of the instrument and tighten the 5. four screws. Do not over-tighten.

Figure 1. Pro2030 with battery cover removed. Notice

battery symbols indicating polarities.

The waterproof instrument case is sealed at the factory and is not to be opened, except by authorized service technicians. Do not attempt to separate the two halves of the instrument case as this may damage the instrument, break the waterproof seal, and will void the warranty.

CONNECTING THE SENSOR AND CABLE

Figure 2, Keypad

“Bulkhead” refers to the single-pin connector at the end of the probe/cable assembly where the dissolved oxygen (DO) sensor is installed (figure 3). The conductivity and temperature sensors are located above and next to the bulkhead respectively and are not user-replaceable.

When a dissolved oxygen sensor is not installed in the cable, the sensor and cable’s bulkhead connectors are not water-proof. Do not submerge the cable without a sensor installed. Submerging the cable without a sensor installed may cause permanent damage to the cable that is not covered under warranty.

Push the sensor into the connector on the cable until it is firmly seated and 5. only 1 o-ring is visible. Failure to properly seat the sensor may result in damage. Twist the sensor clockwise to engage the threads and finger tighten. Do 6. NOT use a tool. This connection is water-tight.

For more detailed instructions, please refer to the sensor installation sheet that is included with each sensor.

CONNECTING THE PROBE/CABLE ASSEMBLY TO THE INSTRUMENT

Figure 3

INSTALLING THE DISSOLVED OXYGEN SENSOR

The Pro2030 has two compatible dissolved oxygen sensors:

Polarographic – This sensor has a black sensor body and is engraved with the model number 2003. Polarographic will be abbreviated Polaro in the instrument’s menu.

Galvanic – This sensor has a grey sensor body and is engraved with the model number 2002.

For information on the differences between these two types of sensors, see Sensor Type in the System Setup Menu section of this manual.

Before installing either sensor or connecting the cable to the instrument, the Sensor Type must be configured for the sensor being installed/ connected. Failure to do this may result in damage not covered under warranty. The instrument will step you through this setup the first time

the instrument is powered on. See the System Setup Menu section of this manual for instructions on configuring the Sensor Type after the first power on.

Remove the red plastic plug from the cable’s bulkhead port by pulling it 1. straight out of the port. This can be discarded. Remove the red plastic plug from the sensor’s connector by pulling it straight 2. off the sensor. This can be discarded. Ensure both the sensor connector and bulkhead connector on the cable are 3. clean and dry. Grasp the sensor with one hand and the cable bulkhead in the other. 4.

To connect the cable, align the keys on the cable connector to the slots on the instrument connector. Push together firmly and then twist the outer ring until it locks into place (figure 4). This connection is water-proof.

Figure 4, Note the keyed connector.

MEMBRANE INSTALLATION

The sensing end of the dissolved oxygen sensor is shipped with a protective red cap that needs to be removed before using. Additionally, it is very important to install a new membrane with electrolyte solution onto the sensor after removing the red cap.

Prepare the electrolyte solution according to the instructions on the bottle. After mixing, allow the solution to sit for 1 hour. This will help prevent air bubbles from later developing under the membrane. Ensure you are using the correct electrolyte solution for your sensor. Galvanic sensors utilize electrolyte with a

light blue label on the bottle and Polarographic sensors utilize electrolyte with a white label on the bottle. The dissolved oxygen sensor is supplied with cap membranes specific to the sensor type ordered (Polarographic or Galvanic). 5913 and 5914 membrane kits are for Galvanic sensors and the 5908 and 5909 membrane kits are for Polarographic sensors.

BACKLIGHT

Once the instrument is powered on, pressing the power/backlight key will turn on the display backlight. The backlight will remain on until the key is pressed again or after two minutes of not pressing any key on the keypad.

Remove and discard or save the red protective cap from the dissolved oxygen sensor by pulling it straight off. Thoroughly rinse the sensor tip with distilled or deionized water. Fill the cap membrane 3⁄4 full of electrolyte solution, then tap the cap with a finger to release any trapped air. Be careful not to touch the membrane portion of the cap. Thread the membrane cap onto the sensor, moderately tight. Do not use a tool. It’s typical for some of the electrolyte solution to spill over. It is best to allow the new cap to remain on the sensor overnight before calibrating. For detailed instructions on changing a cap membrane, see the Care, Maintenance and Storage section of this manual.

RUN SCREEN

Press the power/backlight key to turn the instrument on. The instrument will run through a self test and briefly display a splash screen with system information before displaying the main Run screen (figure 5). The first time the Pro2030 is turned on, it will step through language, sensor and membrane selections; see the First Power On section of this manual for more information.

POWERING OFF

To turn the instrument off, press and hold the power/backlight key for three seconds.

NAVIGATION

The up and down arrow keys allow you to navigate through the functions of the Pro2030.

NAVIGATING THE RUN SCREEN

DO LOCAL%

The instrument will step through an initial configuration when powered on for the first time. This will set the language, dissolved oxygen sensor type and membrane type. Use the up or down arrow keys to highlight the appropriate language, sensor and membrane, then press enter to confirm (figures 6). The Sensor Type must be configured for the dissolved oxygen sensor installed on the cable. Failure to do this may result in damage not covered under warranty. If an incorrect option is selected, it may be changed in the System Setup menu.

Figure 6, Select language, dissolved oxygen sensor and membrane.

After selecting a language, sensor and membrane, the Run screen will be displayed. The next time the instrument is powered up, the Run screen will display immediately after the splash screen. If the sensor type or membrane type is changed, ensure that it is updated in the System Setup menu.

SYSTEM SETUP MENU

Press the menu key to access the System Setup menu. The System Setup menu contains multiple screens that are notated as ‘pages’. The current page is indicated near the bottom of the display (figure 7).

Use the up and down arrow keys to scroll through menu options and menu pages.

DO Local% can be enabled or disabled by using the up or down arrow keys to

highlight it and then pressing enter . An ‘X’ in the box next to DO Local% indicates it is enabled (Figure 7).

Figure 7, page 1 of System Setup menu. DO Local% is enabled.

When DO Local% is enabled, DO% values will be expressed as %L on the Run screen.

DO Local% allows for localized % saturation measurements, but does not affect the mg/L readings. When enabled, the DO% calibration value is always 100% regardless of the altitude or barometric pressure of the location. This deviates from YSI’s traditional method of expressing DO% saturation where the % calibration value decreases with a decrease in barometric pressure, i.e. an increase in altitude (Appendix A). To determine the % calibration value when DO Local% is disabled, divide the local barometric pressure pressure in mmHg by 760 and then multiply by 100.

EXITING THE SYSTEM SETUP MENU

To exit the System Setup menu, press the down arrow key until the ESC - Exit box is highlighted, then press enter to return to the Run screen.

Example: 750/760 = 0.9868 x 100 = 98.68% calibration value when DO Local is disabled.

When DO Local% is enabled, the Pro2030 corrects for barometric pressure on each DO measurement instead of during calibration.

Example: Instrument #1 with DO Local% enabled: At 737 mmHg barometric pressure, roughly 841 ft above sea level, the instrument would calibrate to 100%.

When taking measurements at the same location (737 mmHg) in a 20°C fresh water sample that is completely air-saturated, the instrument would read:

DO %L value = 100% DO mg/L value = 8.81 mg/L (9.091 x .96972)

Instrument #2 DO Local% disabled: At 737 mmHg barometric pressure, roughly 841 ft above sea level, the instrument would calibrate to 737/760 x 100% = 96.97%

When taking measurements at the same location (737 mmHg) in a 20°C fresh water sample that is completely air-saturated, the instrument would read:

AUDIO

Audio can be enabled or disabled by using the up or down arrow keys to highlight Audio and pressing enter. When enabled, there will be an ‘X’ in the box next to Audio.

When Audio is enabled, the Pro2030 will beep twice to indicate stability when Auto Stable is enabled. The instrument will also beep when a key is pressed. When Audio is disabled, the Pro2030 will not beep.

CONTRAST

To adjust the display Contrast, use the up or down arrow keys to highlight Contrast, then press enter. Next, use the up or down arrow keys to adjust the contrast. The up arrow key will darken the contrast and the down arrow key will lighten the contrast. After adjusting the contrast, press enter to save and exit the Contrast adjustment option.

DO% value = 96.97% DO mg/L value = 8.81 mg/L (9.091 x .96972)

Hence, the mg/L readings are unaffected by DO Local%.

1.) Value from oxygen solubility table (Appendix B).

2.) 737/760 x 100%, correction for barometric pressure.

LAST DIGIT SUPPRESSION (LDS)

Last Digit Suppression (LDS) can be enabled or disabled by using the up or

down arrow keys to highlight it and pressing enter . An ‘X’ in the box next to LDS indicates it is enabled.

LDS rounds the DO value to the nearest tenth; i.e. 8.25 mg/L becomes 8.3 mg/L. LDS is automatically disabled during calibrations.

QUICK DO CALIBRATION (QUICK DO CAL)

Quick DO Cal can be enabled or disabled by using the up or down arrow keys to highlight Quick DO Cal and pressing enter. An ‘X’ in the box next to Quick DO Cal indicates it is enabled.

When Quick DO Cal is enabled, press and hold the calibration key for 3 seconds while in the Run screen. Next, highlight Dissolved Oxygen and press enter to calibrate the DO sensor to the instrument’s barometer reading. For more information on Quick DO Cal, see the Calibration section of this manual.

EMERGENCY CONTRAST ADJUSTMENT

If necessary, there is an alternate method of adjusting the contrast. To adjust the contrast, press and hold the menu key, then press the up arrow key to darken the contrast or press the down arrow key to lighten the contrast.

SENSOR TYPE

Sensor Type sets the type of dissolved oxygen sensor being used; either Polarographic (black) or Galvanic (grey).

The instrument’s Sensor Type must be configured for the sensor installed.

Use the up or down arrow keys to highlight Sensor Type, then press enter to open a submenu. Highlight the sensor type corresponding to the sensor installed on the cable and press enter to confirm. The enabled sensor type will have an ‘X’ in the box next to it. Next, use the down arrow key to highlight the ESC – Exit, then press enter to save changes and to close the sensor submenu.

Failure to do this may result in damage not covered under warranty. If you observe readings very close to 0 or extremely high readings, i.e. 600%, the Sensor Type setting may be incorrect.
