Operation of this instrument may cause unacceptable interferences to other
electronic equipment, thus requiring the operator to take all necessary steps
to correct interferences. Any variation introduced by the user to the supplied
equipment may degrade the instrument’s EMC performance.
To avoid damages or burns, do not put the instrument in microwave ovens.
For your and the instrument’s safety, do not use or store the instrument in
hazardous environments.

Description
6
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. The digital sensors are
individually serialized and identied by the meter. Once connected to the
meter, they are ready to measure their individual parameters along with
temperature.
The clean user interface permits you to adapt edge™ to your exact
measurement requirements. The intuitive design simplies conguration,
calibration, measurement, data logging and transfer of data to a USB thumb
drive or computer. edge™ also oers a basic operation mode that streamlines
measurement conguration 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
remotely 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 in taking measurements. The following topics are expanded upon in
the sections that follow in this manual.
1. Familiarize yourself to 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.
Setting Up

Setup/Installation 13
Connect the power adapter cable to the
rear socket of the bench cradle. Verify
the battery icon indicates charging when
meter is powered.
Wall Cradle Setup
Choose suitable wall location. Use the
drilling diagram to drill holes as indicated.
(Use 2.5 mm or US #3 bit).
Fasten the wall cradle using the provided
screws. Snap cover over screw heads.
Connect the power adapter cable to the
bottom socket of the wall cradle.
Connect the probe connector to the
socket located at the bottom of edge™.
Slide edge™ into the wall cradle. Verify
the battery icon indicates charging when

Power Connection
Connect the micro USB connector into
the USB socket on the cradle or into the
micro USB socket of edge™. Plug the
5 Vdc adapter into the power supply
socket. edge™ can be also powered by
connecting with a USB cable directly to
a PC.
Note: edge™ is supplied with a
rechargeable battery inside, which
ensures about 8 hours of continuouse
use. Whenever edge™ is connected to
the power adapter or to a PC, the battery
is recharging.
Connect the connector of the probe 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.
If the probe is not connected or not
recognized, “NO PROBE” message is
displayed.

edge™ oers a basic operation mode that streamlines measurement
conguration 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 buers; 6.86, 7.01, 4.01, 9.18
and 10.01 buers. All pH measurements will display, log and export with 0.01

Note:
• If powering edge™ through the micro USB connector to a PC, a SETUP
parameter will require the choice “LOG ON EDGE”.
• 1000 log records can be stored into the 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).
The maximum number of Interval Lots that may be
stored is 100. If a 101st 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. 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 3rd
