1. General Description Model 5000 Features The Model 5000 is a microprocessor based, menu-driven, dissolved oxygen meter designed to perform laboratory measurement of dissolved oxygen and Biochemical Oxygen Demand (BOD). The instrument’s menu system makes it simple to use. The Model 5000 has a new case design which facilitates laboratory measurement. The angled profile makes these instruments both functional and attractive.
Model 5100 Features The YSI Model 5100 has all of the same functionality of the Model 5000 and much more. The YSI Model 5100 is a state-of-the-art, microprocessor-based, dissolved oxygen instrument with many automated and application specific features. The YSI 5100 DO instrument contains built-in application software for the calculation of Oxygen Uptake Rate (OUR) and Specific Oxygen Uptake Rate (SOUR).

3. Quick Start When you unpack your new Model 5000 or 5100 there are several things you’ll want to do to set the instrument up. 1. Inspect the product to assure that it has not been damaged during shipment. 2. Check the packing list to make sure you have received everything you should have. 3. Install the batteries (see 11. Maintenance, Batteries). 4. Plug the power supply into its mating connector on the back of the meter (see 4.3 Rear Panel). 5.
4. Controls 4.1 Front Panel The front panel of the instrument contains the display and keypad as shown below. The front panel display and controls of the 5000 and 5100 are identical.
The 5000/5100 has two main operating modes, Main and Application. The current mode is displayed in the dark bar at the top right corner of the display. The following diagram shows the display while the instrument is in the Main mode. Mode * 8.15 Main mg /L 11:33AM 24.38°C STORE REVIEW SEND CALIBRATE Soft-key functions The bottom row of the display identifies the function of the four soft-keys which are located on the keypad below the display.

4.3 Rear Panel The rear panel contains the connections for the power supply, probe, bar code reader, external computer keyboard and RS232 serial port as shown below. The bar code reader and external computer keyboard share the same socket and are only available on the model 5100. Power Supply Connection The power supply connection requires a 4.5 to 5.5 VDC power supply with at least 350 mA current (6.0 VDC 800 mA when using the YSI 5015 bar code reader).
Bar Code Reader Connection The YSI 5015 bar code reader connects to this 6-pin mini DIN connector. The connector is marked with an arrow to show proper alignment. Be sure to align the arrows when plugging in the YSI 5015 bar code reader (see 7.2 Application Mode, Remote, Bar Code Reader). The bar code connector is also used for attaching an external computer keyboard. Using a keyboard simplifies data entry when using the 5100 in the remote mode, such as with YSI BOD Analyst software (see 7.
5. Setup Before operating the 5000/5100 for the first time, you should set the instrument parameters. Once set, these parameters are maintained in memory. These parameters are discussed below. From Main mode, press the [CALIBRATE] soft-key to enter the calibration menu. Notice that the dark bar in the top right corner of the display shows the current mode. 8.15 mg/L 740 mmHg 11:33AM 98.0 % 0.0 ppt 24.

The [SIZE] soft-key cycles among the two possible display arrangements for Main mode. One selection shows as many parameters as possible, the other shows Dissolved Oxygen in large type with temperature and time in small type. These different display arrangements are for Main mode only. The display will show all parameters in Calibration mode. 8.

Press the [NEXT] soft-key to select the parameter that you want to change. Then press [ENTER] to turn the asterisk character on or off.
5.3 Autostable Setup The autostable feature indicates when readings are stable by emitting a single beep and displaying an asterisk (*) to the right of the dissolved oxygen reading. The instrument uses criteria that you input to determine what a stable reading is. You select the maximum percent of change that may occur during a selected time duration. The default values are 10 seconds and 0.4% variation. The instrument will display an asterisk (*) only when these criteria are met.

The key toggles between an [AUDIO off] soft-key and an [AUDIO on] soft-key. The present state of the beeper would be the OPPOSITE of the function shown on the soft-key. If the beeper is currently on, the soft-key shows “AUDIO off”; i.e., your alternate choice.

Auto Cal 1. Prepare the probe according to the instructions in the Probe Operations Manual. 2. Connect the probe to the meter. 3. Place the probe in a BOD bottle containing about 1″ of water to provide a 100% relative humidity environment. 4. Press [ ] to turn the instrument on. 5. Allow the probe to polarize and the temperature to stabilize for at least 15 minutes. If calibration is performed prematurely the values will drift and may be out of specification. 6.
DO Cal (manual) 1. Prepare the probe according to the probe instructions. 2. Connect the probe to the meter. 3. Place the probe in a known oxygen environment, such as a BOD bottle containing about 1″ of water to provide a 100% relative humidity environment or a Winkler-titrated sample. 4. Press [ ] to turn the instrument on. 5. Allow the probe to polarize and the temperature to stabilize for at least 15 minutes.

A standard method for creating such an environment is to dissolve excess sodium sulfite (Na2SO3) and a trace of cobalt chloride (CoCl2) in water. Preferably, the water should come from the sample to be measured. These chemicals will remove all oxygen from the sample (See Standard Methods for the Examination of Water & Wastewater, method 4500-O G, 19th edition). Alternatively, you may place the probe in 100% nitrogen gas. 1.

9. Principles of Operation YSI dissolved oxygen probes use membrane-covered, Clark-type polarographic sensors with built-in thermistors for temperature measurement and compensation. A thin permeable membrane, stretched over the sensor, isolates the sensor elements from the environment, but allows oxygen and certain other gases to enter. When a polarizing voltage is applied across the sensor, oxygen that has passed through the membrane reacts at the cathode, causing a current to flow.
10. Understanding Dissolved Oxygen Error Factors The major sources of error in DO measurement are the accuracy of the instrument components, the accuracy of the probe, and the user’s ability to calibrate the system precisely. Most errors can be reduced substantially by calibrating at DO levels and probe temperatures as close as possible to the expected measurement DO levels and temperatures. In the following, individual sources of error and their ranges are listed.
c. Temperature compensation error: The variation from nominal response to sample temperature is ±0.2% of the DO reading per degree C of the temperature difference between the temperature of the sample and the temperature at which the probe was calibrated. Type 3 Errors: Calibration a. Sample temperature uncertainty error: ±1% of reading This error is approximately zero when using AUTO CAL, when manually calibrating in the % air saturation mode or when calibrating to a Winkler titration sample. b.
