edge® enables the user to make fast, accurate measurements of commonly
measured laboratory parameters using one of the Hanna edge® digital sensors
for pH, Conductivity or Dissolved Oxygen. Each digital sensors has a unique
serial number and the parameter that is measures is automatically identied
by the meter. Once connected to the meter, the sensor(s) are ready to measure
their parameter along with temperature.
The user interface permits you to adapt edge® to your exact measurement
requirements. The intuitive design simplies conguration, calibration,
measurement, data logging and transfer of data to a USB thumb drive
or computer. edge® also oers a basic operation mode that streamlines
measurement conguration and is useful for many routine applications. (Every
feature and measurement detail is designed to give you an edge in measurement
technology.)
edge® 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.

The main operating modes of edge® 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® 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.
Slide edge® into the cradle while
positioning the probe cable behind the
cradle. Put the probe/sensor into the
electrode holder and secure cable in clips.
Connect the power adapter cable to the
rear socket of the bench cradle. Connect
the other end to the power adapter and
plug into line power. Verify the battery
icon indicates charging.
Wall Cradle Setup

battery inside, which provides about 8
hours of continuous use. Whenever edge®
i s connected to the power adapter or to a PC,
the battery is charging.
Connect the 3 mm probe jack to the probe
input located on the bottom of edge®.
Make sure the probe is completely
connected. If the probe is recognized,
“CONNECTING” message is displayed along
with sensor model.

edge® oers a basic operation mode that streamlines measurement
conguration for pH and EC measurements and is useful for many routine
applications. Basic pH SETUP reduces parameter selection to the basic set.
The meter limits calibration to 5 standard pH buers; 6.86, 7.01, 4.01, 9.18
and 10.01 buers. All pH measurements will display, log and export with 0.01
pH resolution. Interval logging is also eliminated. Manual and Manual medium
stability log on demand are still functional. pH CONDITION, RESPONSE graphs
are not displayed, giving the display a “Basic” measurement screen with just pH
data and temperature. Basic EC reduces specic EC SETUP parameters to 3. The
meter defaults settings to common parameters and auto ranges measurements
automatically. The Basic EC meter may be used for conductivity and TDS
measurements (salinity is not available). Interval logging is also eliminated.
Manual and Manual medium stability Log on demand are still functional.
Note
:
• If powering edge® 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® memory. This memory is shared
between all measurement types (pH, EC, DO) 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.
Each time an Interval log is initiated, a new lot is
created. The maximum number of Interval lots that
may be stored is 100. If a 101
st
lot is attempted, “MAX
LOTS” will be displayed. Some lots will need to be
deleted. The lot numbering is up to 999 and restarts if
all lot logs are deleted. All log on demand and stability
log on demand are stored in a single lot. The maximum
number of records that may be stored in a Manual or
Stability lot is 200 records.
If the log memory is full during any logging session,
the “LOG FULL“ message will be displayed on the
third LCD line for a brief moment and logging will
cease. The display will return to the measurement
screen.
Logging type is congured in SETUP.
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 dierent 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 MODIFY then use the u arrow to
select between Interval, Manual, or Stability. When Interval is displayed, use the
p and q arrows to select the setting for the timed interval. When Stability is
displayed, use the p and q 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 (Not available in Basic
mode). To start Interval logging, press the LOG key while the instrument is in
measurement mode.
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 on continuously during
active logging.
Pressing u 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. The “PLEASE WAIT” screen will

• If “ºC !” appears in log data, the electrode/probe was used beyond it’s
operation specications and the data is not considered reliable.
• If “ºC !!” appears in log data, the temperature sensor within the probe or
electrode is broken and the device should be replaced. Logged data should
not be considered reliable.

Basic vs
Standard
pH Mode
For optimum pH measurements, follow these steps:
1. Understand the benets and features of Standard and Basic Operation.
2. Set up edge® meter by conguring preferences.
3. Calibration
4. Measurement
The “Standard” pH operation includes up to a 5-point buer calibration, use
of custom buers, choice of displaying 0.001 pH resolution, use of the full
diagnostic features of Calibration Check™ (that includes buers used, probe
condition, response time and messages indicating a contaminated buer or pH
sensor requiring maintenance during calibration). Additional Sensor Check™
indicators are available if using HI 11311 or HI 12301 pH electrodes. These
include a continuous diagnostic to detect if the electrode is broken and at the
time of calibration, a diagnostic to indicate the reference junction has been
compromised or fouled by sample contamination. The Standard pH operation
also includes full logging capability including Interval, Manual log on demand
and Manual log on stability.
“Basic” pH operation provides a simplied SETUP menu; there are no decisions
to make regarding the pH measurement itself. The meter will display 0.01 pH
resolution and permit a 3-point buer calibration from the following pH buers;
4.01, 6.86, 7.01, 9.18 or 10.01. Calibration Check™ and Sensor Check™ features
are limited to messages during calibration. Calibration reminders are also not
available. The GLP will still provide oset, slope, buers used and a calibration
date. The Basic pH operation includes Manual log on demand and Manual log on
stability (medium setting).
Note
: When changing from Standard to Basic operation in SETUP, previous
calibration data will be cleared. A prompt will force the user to facilitate this.
