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.

LOGGING FUNCTION
Note: If powering edge® DO through the micro USB connector to a PC, a SETUP option will
require the choice “LOG ON EDGE” or “EXPORT TO PC“.
1000 log records can be stored into edge® DO memory. This memory is shared between and
all logging types (Manual, Manual Stability, Interval logs).
The maximum number of records for an Interval lot is 600 records (provided log space is
available).
A record is a stored reading and a lot is a group of records.
Types of Logging
Interval logging: A continuous log recorded using a user‑selected timed period. (This is not
available in Basic mode).
Manual log on demand: Readings are logged each time LOG key is pressed. All of the records
are stored in a single Manual lot for the measurement type. New records made on different days are
stored in the same Manual lot.
Manual Stability log on demand: A log on demand that is made each time LOG key is pressed
and the stability criteria is reached. Stability criteria may be set to Fast, Medium or Accurate settings.
In Setup mode, choose log parameter, press CAL/MODIFY key then use the RANGE/ukey to
select between Interval, Manual, or Stability. When Interval is displayed, use th e and keys to
select the setting for the timed interval. When Stability is displayed, use the and to select the
measurement stability setting.
A complete set of GLP information including date, time, range selection, temperature reading,
calibration information and probe serial number is stored with each log made.
Interval Logging
Select Interval and sampling period in the SETUP menu. To start Interval logging, press the LOG key
while the instrument is in measurement mode.
SETUP/INSTALLATION

17
A “PLEASE WAIT” message will be displayed followed by the number of
free spaces. During active interval logging, lot information is displayed
on the third LCD line. The line indicates in which lot the data will be
placed and keeps track of the number of logged records taken. The
“LOG“ tag is continuously on during active logging.
Pressing RANGE/ukey during an interval log will display the number
of logs available.
Pressing the LOG key again will stop the Interval logging session. The
“LOG STOPPED“ message will be displayed for a few seconds.
If a sensor failure occurs during interval logging, the message “OUT OF
SPEC.” will alternate with logging information.
Manual Logging
Select Manual in the SETUP menu. To initiate a Manual log, press the
LOG key while the instrument is in measurement mode. The “PLEASE
WAIT” screen will be displayed briefly followed by a screen indicating
the measurement has been saved and then a screen indicating the log
record number.
The “LOG” tag will be displayed on all 3 screens.
“PLEASE WAIT”
“SAVED” with the log record number
“FREE” with the number of free spaces available
SETUP/INSTALLATION

Stability Logging
Select Stability and choose measurement stability criteria in the SETUP menu. To initiate the Stability
log, press the LOG key while the instrument is in measurement.
The “PLEASE WAIT” screen will be displayed briefly followed by a
screen showing the stability tag, “LOG” tag and a “WAITING” message.
The log can be stopped while the “WAITING” message is displayed by
pressing LOG key again.
When the stability selected criteria has been met, a “SAVED” message
will be displayed followed by a screen indicating how much log space is
available. The “LOG” tag will be displayed on all 4 screens.

VIEWING LOGGED DATA
All log records stored on edge® DO may be viewed on the meter by
pressing the RCL key.
Use the keys to chose the type of logging records to view.
Choices are:
• Manual log on demand lot,
• Manual log on stability lot,
• Individual Interval logging lots.
SETUP/INSTALLATION

19
If no data was logged for the selected measurement range, the
instrument displays the following messages:
• “NO MANUAL LOGS”
• “NO STABILITY LOGS”
Press GLP/CFM key to enter inside lot information to view recorded
data. Use the keys to toggle between different records.
Use RANGE/uto display GLP data including calibration information, date, time, etc.
Press SETUP/CLR key then GLP/CFM key when deleting records or lots.
Press RCL key to exit the logging type.
Press RCL key to return to the measurement screen.
Delete Logging Type/Lot
Press RCL followed by GLP/CFM key.
Use the keys to select the Manual/Stability records or Interval lots to delete.
Press SETUP/CLR key. The instrument will display “CLEAR MANUAL” for Manual Records, “CLEAR
STAB” for Stability Records.
For Interval lots, the message “CLEAR”, followed by the selected lot will
be displayed with “CFM” tag blinking.
Press the keys to select a different lot. Press GLP/CFM key. The
instrument will display “PLEASE WAIT”.
“CLEAR DONE” is displayed for a few seconds after the selected Interval
lot is deleted.
Delete Records (Manual and Stability log on demand)
To delete individual records (Manual and Stability logs only), enter
Manual (Stability) log by pressing GLP/CFM key when Manual (Stability) is displayed.
Use the keys to sel ect the record to be deleted and then press SETUP/CLR key.
The instrument will display “CLEAR REC.“ and record number along
with “CFM” tag blinking. Use the keys to select another record
if necessary.
SETUP/INSTALLATION

20
Press GLP/CFM key. The instrument will display “PLEASE WAIT” and then “CLEAR DONE” message.
When individual logs are deleted within saved MANUAL or STABILITY logs, the logs will renumber,
filling in the deleted data but staying in chronological order.
To delete all records of the MANUAL (STABILITY) log, proceed as described on page 19 for LOTS.
Select the Manual (Stability) lot and press SETUP/CLR key. The
”CLEAR” message will be displayed along with ”MANUAL” or
“STABILITY” and CFM tag blinking on the LCD. Press the GLP/CFM key
to confirm the deleting of the selected lot (MANUAL or STABILITY) or all
records. Press SETUP/CLR key to exit without deleting.
The lot number is used to identify particular sets of data. The lot numbers are allocated successively
until 100, even if some lots were deleted. The total number of lots that can be saved is 100. If
some are deleted (for example 1‑50), fifty additional logs may be stored. These will be numbered
101‑150. The lots are allocated successively (provided available memory space) until 999 is reached.
After this, it is necessary to delete all the LOT logs to start over the numbering.
Delete All
All logs, may be deleted in a single clear. This function will delete all MANUAL, STABILITY and
INTERVAL logs.
Press the RCL key. The DO type will be blinking. Use RANGE/ukey to
select desired measurement parameter log data to delete.
While the measurement type is blinking and message states “LOG
RECALL”, press SETUP/CLR key.
“CLEAR ALL” and measurement type will be displayed with “CFM” tag
blinking. Press GLP/CFM key.
“PLEASE WAIT” and the percent cleared will be displayed until
completed. The procedure can be repeated for the other measurement
modes.
Note: If SETUP/CLR key is pressed in error, press SETUP/CLR key
again to exit without deleting.
