BASIC MODE
edge® blu offers a basic operation mode that streamlines measurement configuration for pH
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 buffers: pH 6.86, 7.01, 4.01,
9.18 and 10.01 buffers. 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 graph is not displayed, giving the display a “Basic” measurement screen
with just pH data and temperature.
SETUP/INSTALLATION
pH CONFIGURATIONS
Once a HALO™ probe is connected to a meter, all Probe specific parameters will be visible in the
SETUP menu.
edge’s pH meter operation is configured by using the SETUP/CLR key with a pH probe connected to
the meter. The parameter-specific options will be seen inserted into the menu. If Basic mode is “On”,
the pH parameter list will not be displayed. See Basic mode for a description of this operation before
choosing how to SETUP the meter.
LOGGING FUNCTION
Note: If powering edge® blu 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® blu memory. This memory is shared between 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
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. 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.
17
SETUP/INSTALLATION

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.
For optimum pH measurements, details follow below:
1. Understand the benefits and features of Standard and Basic Operation.
2. Connect the HALO™ probe to the edge® blu.
3. Set up edge® blu meter by configuring preferences.
4. Calibration.
5. Measurement.
24
The “Standard” pH operation includes up to a 5-point buffer calibration, use of custom buffers,
choice of displaying 0.001 pH resolution, use of the full diagnostic features of Calibration Check™
(that includes buffers used, probe condition and messages indicating a contaminated buffer or pH
sensor requiring maintenance during calibration).
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 simplified SETUP menu; there are no decisions to make regarding
the pH measurement itself.
OPERATIONAL GUIDE
BASIC VS. STANDARD pH MODE
The meter will display 0.01 pH resolution and permit a 3-point buffer calibration from the following
pH buffers; pH 4.01, 6.86, 7.01, 9.18 or 10.01. Calibration Check™ features are limited to
messages during calibration. Calibration reminders are also not available. The GLP will still provide
offset, slope, buffers 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.
Major differences between Standard and Basic modes are shown below.

OPERATIONAL GUIDE
CONNECTING THE HALO™PROBE
Power the edge® blu meter by pressing the ON/OFF button on the top of the meter. The Bluetooth logo
and “SCANNING” will appear in the message area. Immediately press the operation button on your
HALO™ probe. The blue halo on the probe will start blinking every half second indicating it is in
discoverable mode. If this is the first connection to the probe, and is the only HALO™ in discoverable
mode, the message will change to “CONNECTING” and the probe model will appear,followed by a
cap removal reminder and then the measurement screen.
If more than one probe is available, the desired probe must be selected (
) and confirmed to
connect (GLP/CFM key). If a previously associated probe is in STANDBY or in discoverable mode
when scanning, the meter will automatically connect to that probe.
pH CALIBRATION
Calibration in Standard Mode
pH operation in standard mode offers full function of edge® blu. This includes seven standard buffers
and two custom ones. Five pH buffers may be used for calibration.
The instrument should be recalibrated whenever:
• High accuracy and sensor verification are required.
• The filling solution of the electrode is replaced (refillable probes only).
• At least once a week.
• After testing aggressive chemicals.
• If ”CAL DUE” is displayed on the third LCD line.
Every time you calibrate the instrument use fresh buffers and perform electrode maintenance as
required. It is advised to choose calibration buffers that bracket the sample pH.
Preparation
Pour small quantities of the buffer solutions into clean beakers. If possible, use plastic to minimize
any EMC interferences. For accurate calibration and to minimize cross-contamination, use two
beakers for each buffer solution; one for rinsing the electrode and one for calibration. If you are
measuring in the acidic range, use pH 7.01 or 6.86 as the first buffer and pH 4.01 as the second
buffer. If you are measuring in the alkaline range, use pH 7.01 or 6.86 as first buffer and pH 10.01
or 9.18 as the second buffer.
Procedure
Calibration can be performed using up to five calibration buffers. For accurate measurements, a
minimum of a three-point calibration is recommended. The calibration buffer can be selected from
the calibration buffer list that includes the custom buffers and the standard buffers:
pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45.
26
The instrument will automatically skip custom buffers which are in a ±0.2 pH window of an already
calibrated buffer.
Submerse the pH electrode approximately 3 cm (1¼”) into a buffer solution and stir gently. Press
CAL/MODIFY key to enter calibration.
OPERATIONAL GUIDE
The custom buffers allow the user to calibrate in a buffer solution different from a standard one. Two
custom buffers can be set in SETUP menu. See page 28 for more information about using custom
buffers.
The “CAL” tag will appear and the “7.01” buffer will be displayed on the
third LCD line. If necessary, press the
keys to select a different buffer
value. The “ ” along with “STIR” tag will be displayed and “WAIT” will
blink on the LCD until the reading is stable.
When the reading is stable and close to the selected buffer, “CFM” tag will
blink. Press GLP/CFM key to confirm calibration.
After confirming the first point, the calibrated value will be displayed on
the first LCD line and the second expected buffer value on the third LCD
line (i.e. pH 4.01).
Rinse and submerse the pH electrode approximately 3 cm (1¼”) into the second buffer solution and
stir gently. If necessary, press the
keys to select a different buffer value.
The “ ” along with “STIR” tag will be displayed and “WAIT” will blink on the LCD until the reading
is stable.
When the reading is stable and close to the selected buffer, “CFM” tag will blink.
Press GLP/CFM key to confirm calibration.
Repeat procedure with additional pH buffers. A total of five pH buffers can be utilized.
After confirming the last desired buffer calibration points, press
CAL/MODIFY key (or if all five buffer values were calibrated) the
instrument will automatically display “SAVING” as it stores information.
It will then return to normal measurement mode.
Each time a buffer is confirmed, the new calibration data replaces the old data for the corresponding
buffer or for any buffer in the proximity of ±0.2 pH.
27
OPERATIONAL GUIDE
If current buffer has no previous data stored and the calibration is not full
(five buffers), the current buffer is added to the existing calibration. If the
existing calibration is full, the instrument asks which buffer to replace.
Press the
keys to select another buffer to be replaced.
Press the GLP/CFM key to confirm the buffer that will be replaced.
Press the CAL/MODIFY key to leave calibration without replacing.
Note: If the replaced buffer is outside the ±0.2 pH window of the calibrated buffers, it is
possible to select this buffer during the next calibration.
Working With Custom Buffers
If a custom buffer was set in SETUP menu, it can be selected during calibration by pressing the
keys. The “C1” or “C2” tag will be displayed once selected.
Press RANGE/u if you want to modify the custom buffer value. The
buffer value will start blinking.
Use the
keys to change the buffer value. After 5 seconds, the buffer
value is updated. Press u if you want to change it again.
Note: Custom buffer values can be adjusted ±1.00 pH around the set value during calibration.
When a custom buffer is displayed, the “C1” or “C2” tag is displayed.
First Calibration Point
When performing a new calibration, or adding to an existing one, the user has a choice of how the
first new calibration point will be treated in reference to the existing calibration point. This is selected
in SETUP by the option FIRST CALIBRATION POINT. The two SETUP selectable options are “POINT”
or “OFFSET”.
Point: A buffer value can be recalibrated and added to the previous calibration set. The electrode
slope of the other calibration points will be reevaluated with the recalibrated buffer value.
28
Press CAL/MODIFY key. Place sensor in desired buffer and select buffer from choices. When sensor
has equilibrated, the CFM tag will turn on and blink. Press the GLP/CFM key.
Press CAL/MODIFY key to escape the calibration. Alternately continue calibrating in additional
buffers. The latest calibration point will be added to the existing data. GLP will reflect the latest
calibration data. Older calibration buffers will be seen as blinking buffers.
OPERATIONAL GUIDE
Offset: The new buffer calibration point can create a constant offset to all existing pH calibration data
(existing calibration must have a minimum of two pH buffers).
Recalibrating a pH sensor or adding to an existing calibration is simple and follows the PROCEDURE
outlined on page 26.
Note: Each time a buffer is confirmed, the new calibration
data replaces the old data for the corresponding buffer or
for any buffer in the proximity of ±0.2 pH. If the current
buffer has no previous data stored and the calibration has not
used five buffers, the current buffer is added to the existing
calibration. If the existing calibration is full, the instrument asks which buffer to replace.
When using Standard mode, the user can choose if they want the display to show CONDITION
gauges on the display. These are part of the Cal Check™ system and are selected in SETUP
by the option INFORMATION. The choice is ON or OFF.
Electrode Condition
edge® blu pH Calibration Check™ feature will assess electrode condition during each calibration and
display it for the rest of the day.
The condition gauge shows the electrode’s condition that is based on the offset and slope
characteristics of the pH electrode at the time of calibration. This gauge reflects the electrode’s
performance and should be expected to slowly decrease over the life of the electrode.
If the instrument is not calibrated the calibration history has been deleted, or it has been calibrated
only at one point, the electrode condition gauge will be empty.
29
OPERATIONAL GUIDE
For a continuous display of the electrode’s condition, daily calibration is necessary. This information
can also be viewed in the GLP data.
Calibration in Basic Mode
Procedure
Basic mode operation permits up to three-point buffer calibration.
For accurate measurements, at least a two-point calibration is recommended. However, a single
point calibration can also be used.
The calibration buffers can be selected from the calibration buffer list that includes the standard
buffers, pH 4.01, 6.86, 7.01, 9.18 and 10.01.
Three-Point Calibration
Submerse the pH electrode approximately 3 cm (1¼”) into a buffer solution and stir gently. Press
CAL/MODIFY key. The “CAL” tag will appear and the “7.01” buffer will be displayed on the third
LCD line. If necessary, press the
keys to select a different buffer value.
The “ ” along with “STIR” tag will be displayed and “WAIT” will blink
on the LCD until the reading is stable.
When the reading is stable and close to the selected buffer, the “CFM” tag
will blink. Press GLP/CFM key to confirm calibration.
After confirming the first calibration point, the calibrated value will be
displayed on the first LCD line and the second expected buffer value on the
third LCD line. (i.e. pH 4.01)
Rinse and submerse the pH electrode approximately 3 cm (1¼”) into the
second buffer solution and stir gently.
If necessary, press the
keys to select a different buffer value.
The “ ” along with “STIR” tag will be displayed and “WAIT” will blink on the LCD until the reading
is stable. When the reading is stable and close to the selected buffer, the “CFM” tag will blink. Press
GLP/CFM key to confirm calibration.
30
After the second calibration point is confirmed, rinse and submerse the pH electrode approximately 3
cm (1¼”) into the last buffer solution and stir gently.
If necessary, press the
keys to select a different buffer value.
The “ ” along with “STIR” tag will be displayed and “WAIT” will blink on the LCD until the reading
is stable.
When the reading is stable and close to the selected buffer, the “CFM” tag will blink. Press
GLP/CFM key to confirm calibration.
At the end of calibration the instrument displays “SAVING”, stores the calibration value and returns
to normal measurement mode.
The calibration sequence may be reduced to two buffer values or a single one. Press CAL/MODIFY
key to return to measurement mode after the desired number of buffers have been calibrated.
OPERATIONAL GUIDE
The calibrated value is then displayed on the first LCD line and the third expected buffer value on
the third LCD line.
Note: When performing a new calibration or adding to an existing calibration the first
calibration point will be treated as an offset. See page 28 for details.
Press CAL/MODIFY key after the first or second calibration point are confirmed and the
instrument will store the calibration data. Then it will return to measurement mode.
If the value measured by the instrument is not close to the selected buffer, “WRONG BUFFER”
will blink. Check if the correct buffer has been used, or selected. If measured value differs more
than expected value “CHECK ELECTRODE CHECK BUFFER” will be displayed. Take appropriate
action, cleaning the probe if necessary and refreshing the pH buffer.
If the buffer temperature exceeds the temperature limits of the buffer, “WRONG BUFFER
TEMPERATURE” will be displayed.
Press SETUP/CLR key after entering calibration to clear previous calibrations stored on probe.
“CLEAR CALIBRATION” message will be displayed. Press GLP/CFM key. The instrument will
return to measurement mode displaying the “CAL DUE” message.
31
OPERATIONAL GUIDE
pH Buffer Temperature Dependence
Calibration buffers are affected by temperature. During calibration with standard pH buffers (not
Custom), the instrument will display the pH buffer value at 25 ºC, however, it will use the value for
that buffer at the temperature of calibration. Immediately after exiting calibration, the buffer will
read its value at the temperature of measurement.

CALIBRATION MESSAGES
The Calibration Check™ feature may flag diagnostic messages during a calibration. As electrode
aging is normally a slow process, substantial changes from previous calibrations are likely due to a
temporary problem with the probe or buffers that can be addressed easily. These messages are seen
in Standard and Basic modes.
Wrong Buffer
This message appears when the difference between the pH reading
and the value of the selected buffer is too great. If this error message
is displayed, check if you have selected the proper calibration buffer and
have poured the desired buffer.
32
OPERATIONAL GUIDE
Wrong Old Points Inconsistency
“WRONG OLD POINTS INCONSISTENCY” is displayed if the new calibration
differs significantly from the last value of that probe in that buffer. In this
case it may be best to clear the previous calibration and attempt a new
calibration with fresh buffers.
To clear calibration information, press CAL/MODIFY key then press
SETUP/CLR key. The “CLEAR CALIBRATION” message will be displayed.
Either press the GLP/CFM key and clear all calibration information or press
CAL/MODIFY key to exit. Probe may retain a single point cal if first point
was accepted.
Once calibration information is cleared, the message “CAL DUE” will be
displayed.
Clean Electrode
“CLEAN ELECTRODE” indicates poor electrode performance (offset out
of accepted window, or slope under the accepted lower limit). Often,
cleaning the probe will improve the pH electrodes response. See pH
Electrode Conditioning and Maintenance for details. Repeat calibration
after cleaning.
Check Electrode Check Buffer
“CHECK ELECTRODE CHECK BUFFER” appears when electrode slope
exceeds the highest accepted slope limit. You should check your probe and
use fresh buffer. Cleaning may also improve this response.
Bad Electrode
“BAD ELECTRODE” appears if the cleaning procedure performed as a
result of the above two messages is found to be unsuccessful. In this case
it is advised to replace the probe.
Wrong Buffer Temperature
“WRONG BUFFER TEMPERATURE” appears if the temperature of the
buffer is outside the defined buffer temperature range. The calibration
buffers are affected by temperature changes in a defined manner.
33
OPERATIONAL GUIDE
During calibration, the instrument will automatically calibrate to the pH value corresponding to the
measured temperature but display it to the value at 25 ºC. Immediately after calibration, the buffer
should read the value of the buffer at the temperature of measurement.
Note: Temperature limits will be reduced to actual sensor specifications.
Contaminated Buffer
“CONTAMINATED BUFFER” appears in order to alert that the buffer
could be contaminated. Refresh your buffer and continue the calibration
procedure.
Broken Temperature Sensor
If the temperature sensor should malfunction or break at any time, a
temperature of “25.0 ºC” will blink on the second LCD line and the
message “BROKEN TEMPERATURE SENSOR” will appear on the third LCD
line after leaving calibration. The calibration will have the compensation
at 25 ºC. Replace probe if this occurs.
Note: If this occurs during logging “25 ºC !” will appear in the *.CSV file.
pH GLP INFORMATION
Good Laboratory Practice (GLP) refers to a quality control function used to ensure uniformity of sensor
calibrations and measurements. The dedicated GLP/CFM key opens a file of the latest calibration
information. Use the
keys to scroll the stored information. This includes the buffers used,
temperature of the buffer, time and date of the last calibration, the sensor serial number and the
calculated offset and percent slope. This information is available in Basic and Standard Modes. This
information is also included with every data log. Newest calibration points report as a solid number,
older calibration data (that is still used) will be displayed blinking.
If calibration has not been performed, the instrument displays a blinking
“NO CAL” message.
After the calibration has been performed, the instrument displays offset
and slope. The GLP slope is the average of the calibration slope; the
percentage is referenced to the ideal slope value at 25 ºC. Additionally,
the condition and response indicators displayed are from the last
calibration.
34
Note: If a custom buffer was used in calibration, the “C1” and “C2” tags will be displayed. If
only the one buffer is used in calibration, the tag will be “C1” and the value will be displayed.
If disabled, “EXPIRATION WARNING DISABLED” is displayed.
OPERATIONAL GUIDE
Pressing the
keys, the last calibration date (yyyy.mm.dd) together
with the current reading is displayed.
Or if enabled the number of days until the calibration alarm “CAL DUE”
will be displayed. (i.e. “CAL EXPIRES IN 2 DAYS”)
The number of days since the calibration expired. (i.e. “CAL EXPIRED 2
DAYS AGO”).
The abbreviated probe serial number together with the current reading.
(See Setup for Full Serial Number).
If a buffer is not from the last calibration, the buffer tag will be displayed
blinking. If the calibration date and time are not in sync with the current
date and time set on meter, the message “Inconsistent GLP time stamp“
will be displayed.
In Standard Mode, Condition gauge is visible on the day of calibration (See Electrode Condition
page 29). If configured in SETUP, a countdown message displays the number of days remaining until
a new Calibration is due.
35
OPERATIONAL GUIDE
pH MEASUREMENT
When a HALO™ probe is connected, the instrument will recognize it
and a cap removal message will be displayed. Press any key to skip the
message. The instrument will enter measurement mode. Make sure the
electrode has been calibrated before taking measurements.
Rinse the pH sensor with water and a sample if possible. Submerse
the electrode tip approximately 3 cm (1¼”) into the sample to be
tested and stir sample gently. Allow time for the electrode to stabilize.
If measurements are taken successively in different samples, it is recommended to rinse the electrode
thoroughly with deionized water or tap water and then with some of the next sample to prevent crosscontamination. The pH reading is affected by temperature. The temperature effect is compensated
for using the temperature sensor inside the probe. The resulting measurement is the actual pH at the
temperature of measurement.
The pH is displayed on the first LCD line and the temperature on the second LCD line. If the reading is
out of measurement range, the closest full scale value will be displayed blinking on the first LCD line.
During measurement useful information can be displayed on the third LCD line by using the
keys. Information is illustrated:
Offset and average slope (if the probe was calibrated)
Note: 100% slope will be displayed if a single point calibration
was made.

The probe will not auto-connect if configured to shutdown. It will autoconnect if configured to standby to this probe in the current work session.
If probe disconnect mode in General Setup Menu is set to SHUTDOWN, the probe will turn off after
several seconds, in order to save battery life. If the option in Setup is STANDBY, the probe will stay in
continuous advertising, but in economy mode; it is visible only for the current meter and the LED will
stop blinking. In order to connect to a different meter, press the button on the probe once.

OPERATIONAL GUIDE
Error Messages During Measurement
If the pH or temperature exceeds the limits of the sensor, the message “ELECTRODE OUT OF SPEC” will
scroll on the third LCD line. The temperature will continue to be displayed.
If temperature exceeds the meter specification of 120 ºC, then “120 ºC”
will blink on the display. If interval logging, the message “OUT OF SPEC.”
will alternate with the LOG specific message. In both these cases and the
Log file will indicate a “ºC!” next to the data.
In case the temperature sensor is damaged, “BROKEN TEMPERATURE

MAINTENANCE
pH PROBE MAINTENANCE
New Probe
pH probes are shipped with a cap that protects the bulb and junction from damage. When using a
new probe, remove the protective bulb cap and inspect for damage.
Thoroughly rinse the probe with water to remove salt deposits that may have formed on the external
surface of the probe during storage or shipping. The presence of salt deposits is normal. During
transport, air bubbles may have formed inside the glass bulb. The temperature sensor is inside the
pH bulb also and may restrict solution movement. Shake down the probe to ensure the internal buffer
is in full contact with the inside of the pH bulb. Calibrate a new probe before measuring samples.
Measurement
Verify the HALO™ has been calibrated before taking measurements.
During measurement, always operate the probe with the pH sensing bulb facing down and the
ceramic junction covered with solution. Use mechanical support (electrode arm) to steady the probe
and allow hands free operation. Rinse the probe with deionized or distilled water between samples
and dab dry with a lab wipe or disposable absorbent towel between samples. If measurements are
made continually, periodically re-check calibration (if possible every 1-2 hours) to ensure the probe
has remained calibrated. Be careful not to wet the black halo (electronics module) on the probe.
39
MAINTENANCE
Storage
The glass sensing bulb on a pH probe should always be kept wet. If dry, remedy by soaking the pH
bulb and reference junction in HI70300 Storage Solution or if absent, pH 4.01 buffer. Soak for a
minimum of one hour; an overnight soak is best. This will hydrate a dehydrated glass sensor and wet
a dry reference junction.
Do not store the probe in ultrapure water. The pH glass surface can actually become dehydrated if
stored or used in deionized or distilled water as ions are leached from sensing surface. pH electrodes
require ions in a solution, preferably with a conductivity exceeding 200 mS/cm to function properly.
Cleaning Solutions
A sensor or reference that is coated or fouled in any way may produce drifty sluggish measurements.
To ensure the best pH measurement possible, preventative maintenance and storage practices
are strongly advised. A clean, conditioned Hanna Instruments pH electrode will provide the
best measurement possible. Always use fresh buffers with each calibration; dirty electrodes can
contaminate buffer solutions. Hanna Instruments manufactures a full line of cleaning solutions
formulated to address general and specific cleaning needs.
For general cleaning, soak sensor tip in HI7061 General cleaning solution for approximately
30 minutes. This will dissolve mineral deposits and other general coatings. After performing any
cleaning procedure, rinse the electrode throughly with distilled/deionized water and soak the
electrode in HI70300 Storage solution for at least 1 hour before calibration or making measurements.
There are other cleaning and disinfection reagents available from Hanna Instruments, formulated for
specific contaminants.
Use diagnostic messages to aid pH electrode troubleshooting. Several cleaning solutions are
available:
• General – Soak in Hanna Instruments HI7061 or HI8061 General Cleaning Solution for
approximately ½ hour.
• Protein –Soak in Hanna Instruments HI7073 or HI8073 Protein Cleaning Solution for
15 minutes.
• Inorganic – Soak in Hanna Instruments HI7074 Inorganic Cleaning Solution for 15
minutes.
• Oil/grease – Rinse with Hanna Instruments HI7077 or HI8077 Oil and Fat Cleaning
Solution.
Note: After performing any of the cleaning procedures, rinse the electrode thoroughly with
distilled water, refill the reference chamber with fresh electrolyte (not necessary for gel-filled
