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. A large graphical display provides
on-screen menus, and large data fields for ease of operation and readability. The angle and
position of the keypad make operation of the 5000 comfortable. The tactile and audio response
from each key stroke give you the confidence that every command has been received.
The Model 5000 is compatible with all existing YSI dissolved oxygen probes when used with the
YSI Model 5011 adapter. The new YSI Model 5010 self-stirring BOD Probe allows you to
operate the probe from the instrument’s power supply, eliminating the need for a separate power
cable for the probe.
Internal memory for storing up to 100 sets of data, and an RS232 port allow you to upload data
from the Model 5000 directly to your computer. Or you can use your Model 5000 with YSI BOD
Analyst software.
Model 5000 Features & Benefits

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). These application features
simplify compliance with USEPA 503 regulations for vector attraction and provide useful tools
for plant operation decisions.
For laboratories with larger volumes, the Model 5100 offers an optional bar code reader and
BOD Analyst software capability. These tools greatly reduce the labor required for processing
BODs and calculating BOD values. The RS232 serial port makes it easy to capture data
electronically.
The model 5000 and 5100 software can be upgraded easily using your computer. When YSI
upgrades these instruments, you’ll be able to get a floppy disk from YSI and simply upgrade the
software in a few minutes.
Calibration of the Model 5100 has been greatly simplified when compared to other dissolved
oxygen instruments. With its internal barometer, the Model 5100 is able to automatically
compensate for changes in barometric pressure so there is no need for charts, altitude information
or external barometric pressure information. The 5100 also has a membrane integrity feature
which will notify you when the membrane needs to be changed.
Model 5100 Features & Benefits
The Model 5100 has all the same functionality as the Model 5000, but with these additional
features:
Additional Feature Benefit
1. Built-in application software for OUR/ SOUR Easy compliance with USEPA 503 regulations.
2. Internal barometer No need to consult external barometer and perform
manual barometric pressure compensation.
3. Automated calibration Saves time and extra steps of manual calibration.
4. Bar-code capability No need to manually type or write the bottle number on
your bench sheet.
5. Port for computer keyboard For some applications, using a keyboard for data entry
will be faster than using the instrument keypad.

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. Prepare the DO probe, as discussed in the Probe Operations Manual, and plug it into
the connector on the back of the instrument.
6. Depress the (on/off ) key (see 4.1 Front Panel).
7. Set the date and time (see 5.4 System Setup).
8. Calibrate the system in a known oxygen environment (see 6.1 Dissolved Oxygen
Calibration).
You are now ready to make dissolved oxygen and temperature readings.

The bottom row of the display identifies the function of the four soft-keys which are located on
the keypad below the display. The function of each of these keys changes with each mode.
The [Mode] key and soft-keys are used to navigate through the menus. The [Mode] key is used to
cycle between the two main operating modes. Pressing a soft-key will bring up a new set of softkey functions (menu). The [Mode] key is also used to backup through the menus to the top level.

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).
Probe Connection
The connector for the probe is an 8-pin mini DIN connector and is marked with an arrow to show
proper alignment. Be sure to align the arrows when plugging in the probe.
YSI 5000 series probes, such as the YSI 5010 BOD probe, will plug directly into the 5000/5100.
If you have an older YSI 5700 or 5900 series probe, the YSI 5011 adapter will be required.
The YSI 5011 adapter has a mini-DIN connector at one end and a 5-pin MS connector and probe
power connector at the other end. The 8-pin mini-DIN connector plugs into the 5000/5100 probe
socket and the 5-pin MS connector plugs into a 5700 or 5900 series probe/cable. The power
connector plugs into the matching connector on a self stirring BOD probe. This allows the
5000/5100 to power the BOD probe, eliminating the need for a separate probe power supply.
NOTE: Do NOT plug the 5011 adapter power connector into the 5000/5100 power supply
socket. Doing so will prevent the 5000/5100 from operating.
9
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 7.2 Application Mode, Remote).
RS232 Connection
The RS232 connection is a standard DB9 connector. See 7.2 Application Mode, Remote, System
Setup for details.

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.
