DESCRIPTION
edge® DO enables the user to make fast, accurate measurements of dissolved oxygen using one of the
Hanna Instruments edge® DO digital sensors for Dissolved Oxygen. Each digital sensors has a unique
serial number that is automatically identified by the meter. Once connected to the meter, the sensor
is ready to measure dissolved oxygen along with temperature.
The user interface permits you to adapt edge® DO to your exact measurement requirements. The
intuitive design simplifies configuration, calibration, measurement, data logging and transfer of data
to a USB thumb drive or computer. (Every feature and measurement detail is designed to give you
an edge in measurement technology.)
edge® DO is versatile in many ways. The slim meter and probe can be used as a portable device
(using its rechargeable battery) or used in its bench or wall cradles (that also power the meter) as a
line‑powered laboratory instrument.

KEYPAD FUNCTION
1. CAL/MODIFY ‑ Used to enter and exit calibration mode. In SETUP, used to initiate changes of a
configuration setting.
2. GLP/CFM ‑ Used to display GLP calibration information. In SETUP, used to confirm change made.
In calibration, used to accept calibration points.
3. RANGE/u‑ Used to select measurement range. In SETUP, used to move to right in pick list. In
log RCL, used to view GLP data for a data point.
4. SETUP/CLR ‑ Used to enter/exit SETUP mode. During calibration, used to clear previous
calibration data. In log RCL, used to clear log records.
5. / ‑ Used to scroll through SETUP menu. Used to change selection when modifying a
parameter in SETUP.
6. RCL (Recall) ‑ Used to view logged records or view % log memory used.
7. LOG ‑ Used to log data by manual log on demand or manual log on stability or to
start/stop interval logging.
Note: You can increase/decrease the speed to change the value of a parameter.
Proceed as follows:
Press and hold down the or key, then slide the finger toward the double
apex to increase the speed that a value changes.

SETUP/INSTALLATION
SETTING UP edge® DO
The main operating modes of edge® DO are setup, calibration, measurement, data logging, and data
export. Follow this general outline of steps to get you started. The following topics are expanded upon
in the sections that follow in this manual.
1. Familiarize yourself with the design features of this unique meter.
2. Decide how the meter will be used and set up the wall or bench cradle in a clean area near
line power.
3. Turn edge® DO on using the ON/OFF button located on the top of the meter.
4. Plug in the probe required for measurement.
5. SETUP the measurement parameters required for the measurement you will be making.
6. Calibrate the sensor/probe.
You are now ready for measurements.
Bench Cradle Setup
Insert electrode holder arm into the post on the pivoting base.
Connect the probe connector to the socket located at the bottom of the instrument.
