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).

The Model 5000 and 5100 are designed exclusively for indoor use and are NOT waterproof. Power The Model 5000 & 5100 are powered by an AC adapter or 4 C-size alkaline batteries. A new set of alkaline batteries will power the selected instrument for approximately 30 hours (not including stirring).
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.
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. Display Soft-Keys Power ENTER Key ON/OFF MODE Key...
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.

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 7.2 Application Mode, Remote).
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.
5.1 Display Setup Press the [DISPLAY] soft-key to show the following menu. Display 8.15 24.38°C 11:33 SIZE UNITS CONTRAST LAST DIG. 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.

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.

AUTO CAL on a Model 5100, you must check the barometric pressure reading and calibrate the barometer, if necessary, as shown under 6.1 Dissolved Oxygen Calibration, Barometer. The Model 5000 does not contain a barometer, therefore, the current barometric pressure must be entered before an AUTO Cal is performed.
7. Model 5100: Verify that the barometer reading is correct. Calibrate the barometer, if necessary, as shown under 6. Dissolved Oxygen Calibration, Barometer. Model 5000: Enter the current barometric pressure as shown under 6. Dissolved Oxygen Calibration, Barometer. 8. Make sure that the display readings are stable, then press the [AUTO CAL] soft-key to calibrate Dissolved Oxygen.
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.
(±10°C), the barometer calibration should be accurate for approximately 30 days. The Model 5000 does not contain a barometer, therefore, the current barometric pressure must be entered before an AUTO Cal is performed. The pressure value displayed is the setting that was entered and stored during the previous calibration.
NOTE: You may estimate the standard pressure at your altitude by using Appendix B - Pressures and Altitudes. Press [ENTER] to confirm. The message will be displayed, on “PRESSURE CALIBRATION SAVED” the model 5100, as shown below. The model 5000 will display “PRESSURE SETTING SAVED” since it does not contain an internal barometer. mg/L 98.0 8.15...
All oxygen probes have a small background current, even in the absence of oxygen. Model 5000/5100 compensation is based on the average background current of YSI probes. This is the default zero value. Using this average will result in errors with probes whose background current differs from the average.
Page 28
D.O. ”. CALIBRATION SAVED The Model 5000/5100 is calibrated at two points: the calibration value you select, and its default zero. NOTE: When you change the zero calibration point, you offset the other value, so that after zeroing the probe for zero oxygen, you must recalibrate in an oxygen environment.

This current is read and interpreted by the YSI dissolved oxygen meter utilizing customized electronics and software to assure the highest possible accuracy and reliability.
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.
