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.
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.
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
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.

(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.
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.

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
1.800.561.8187
www.
.com
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 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.
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
1.800.561.8187
www.
.com
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
1.800.561.8187
www.
.com
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.
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.
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.
1.800.561.8187
www.
.com
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
1.800.561.8187
www.
.com
The calibrated value is then displayed on the first LCD line and the third expected buffer value on the third LCD line.
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.
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.

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
1.800.561.8187
www.
.com
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.
1.800.561.8187
www.
.com
34
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 º C !” 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.
1.800.561.8187
www.
.com
Pressing the keys, the last calibration date (yyyy.mm.dd) together with the current reading is displayed.
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.
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.

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 cross‑ contamination. 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)

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
1.800.561.8187
www.

40
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 electrodes) and soak the electrode in HI70300 or HI80300 Storage Solution for at least
1 hour before taking measurements.
