For HI 8614 performed by the transmitter's ATC circuitry if the temperature probe (HI 76608, optional) is attached. If ATC is not required, it is possible to substitute the temperature probe with a fixed resistor.
The input is isolated from the current loop to eliminate problems related to ground loop, low insulation cables, multiple electrode connections, and a common mode voltage of up to 100 V ensures true differential readings.
The terminal board of the transmitter provides for connection of power supply, pH or ORP electrodes and temperature probe (for HI 8614 family models only).
The unit is enclosed in a protective casing conforming to IP 65 standards.

INITIAL PREPARATION
• Connect the pH electrode to the BNC socket.
• Connect the temperature probe to the transmitter.
For HI 8614 family only: for automatic temperature compensation, connect
the 2 terminals of the temperature probe (HI 76608, optional) to "TEMP. PROBE" terminals.
If automatic temperature compensation is not required, short the "TEMP. PROBE" terminals with a resistance according to the external temperature:

Pour small quantities of pH7.01 and pH4.01 solution into two clean beakers.
For accurate calibration use two beakers for each buffer solution, the first one for rinsing the electrode, the second one for calibration. In this way contamination of the buffers is minimized.
To get accurate readings, use pH7.01 and pH4.01 if you are going to measure acid samples or pH 7.01 and pH 10.01 for alkaline measurements.
Note: With HI 8614L the instruments
display can be used during calibration without the need to connect the ammeter and the reading is directly expressed in pH units.
A 2 kohm resistor is factory mounted for 25°C temperature compensation.
8 9
PROCEDURE
• Disconnect the +ve supply cable from "+VE LOOP" terminal and connect a 20mA f.s. ammeter between the +ve cable and "+VE LOOP" terminal.
• Adjust the slope trimmer until the ammeter reads 8.58 mA for
HI 8614
and HI 8614L or the display shows "4.01" at 25°C. For
other buffer temperatures, refer to page 12 for the appropriate mA / pH reading.
If you are using pH 10.01 buffer solution adjust the slope trimmer until the ammeter read 15.43 mA at 25°C (77°F) or the value indicated at page 12.
• Remove the protective cap from the electrode, rinse it with some pH 7.01 solution or immerse it in the pH 7 rinse solution, then immerse the pH electrode and temperature probe into pH7.01 calibration buffer solution; shake briefly and wait for the reading to stabilize.
Note: The tip of the electrode should be
submerged approximately 4 cm (1½") into the solution. The temperature probe should be located as close to the pH electrode as possible.
• Adjust the offset trimmer until the ammeter reads 12 mA or the display shows "7.01" if the temperature of the buffer is at 25°C.
For other buffer temperatures, refer to page 12 for the appropriate mA / pH reading.
• Rinse the electrode with tap water or distilled water and a small amount of pH 4.01 or 10.01 buffer solution or immerse it in the pH 4 rinse solution (2nd calibration point). Dip the electrode and the temperature probe into pH 4.01 (or
10.01) calibration buffer solution, shake briefly and wait for a few minutes for reading to stabilize.
FOR HI8614L ONLY
The Display Module is factory calibrated, so that the LCD display results are referred to the 4-20 mA loop current (e.g. LCD displays
0.00 pH when the loop current is 4.00 mA and displays 14.00 pH when the current is 20.00 mA).
Under normal application, adjustment on this module may not be necessary.
If routine check is required, the following procedures shall be performed.
• Follow the procedure at page 10 to perform calibration on the transmitter module (using a ammeter).
• Simulate a 4.00 mA loop current for the transmitter (i.e. 0.00 pH as Electrode input) and check for display reading.
• Simulate a 20.00 mA loop current for the transmitter (i.e.
14.00 pH as Electrode input) and check for display reading.
Note: When HI 8614 or HI 8614L instruments are used in
conjunction with the new Hanna indicator HI 8510 or controllers HI 8710 and HI 8711, the calibration can also be performed on the indicator/controller. In this case slight calibration adjustment can be made on the indicator/ controller even if the whole system calibration is advised, always starting from the transmitter.

INITIAL PREPARATION
Disconnect the +ve supply cable from the "+VE LOOP" terminal and connect a 20 mA f.s. ammeter between the +ve cable and the "+VE LOOP" terminal. With HI 8615L the instrument display can be used during calibration without the need to connect the ammeter. In this case the values are directly expressed in mV units.
Pour a small quantity of HI 7020 ORP solution into a beaker.
PROCEDURE
• Connect the shorting BNC connector to the ORP transmitter.
• Adjust the OFFSET ADJUSTMENT trimmer on the module for a display of 12 mA on the ammeter or 0 mV on the instrument display (HI 8615L only). This sets the zero point for the transmitter.
12 13
• Connect the ORP electrode to the transmitter and immerse the tip of the electrode into a beaker of HI 7020 ORP calibration solution, and check that the ammeter reading lies between 13.6 and 14.2 mA for HI 8615 or the instrument reading is between 200 and 275 mV at 25°C (HI 8615L).
• If the reading lies outside this range, adjust the slope adjustment trimmer on the transmitter for a reading just within this range.
The unit is now calibrated.
A complete calibration of the transmitter module is advised periodically.
This calibration procedure requires the HI 8427 or the HI 931001 pH and ORP simulator to simulate the ORP electrode.
HI 8427 or HI 931001 produce a known signal into the system so that the faults of the system can be isolated.
• Connect the ORP electrode to the module and immerse the tip of
the electrode into the beaker of HI 7020 ORP solution and check that the ammeter reading lies between 13.6 and 14.2 mA for HI 8615,
or the instrument reading is between 200 and 275mV
at 25°C (HI 8615L only).
• Connect the ORP transmitter to the simulator.
• Set the simulator to 0 mV and adjust the offset trimmer to read 12 mA on the ammeter or 0 mV on the HI 8615L display.
• Set the simulator to 350 mV and adjust the slope trimmer to read 14.8 mA for HI 8615 on the ammeter or 350 mV on the
HI 8615L
display.
• Only if the reading lies outside this range, adjust the slope adjustment trimmer on the transmitter to reflect a reading within this range.
FOR HI8615L ONLY
The HI 8615L are factory calibrated, and the displayed values are referenced to the 4-20 mA loop current. Under normal application, adjustment on this module may not be necessary. If routine check is required, the following procedures shall be performed.
• Follow the above procedure for HI 8615
• Simulate a 12.00 mA loop current for the transmitter (i.e. 0 mV at Electrode input) and check display reading.
• Simulate a 20.00 mA loop current for the transmitter (e.g. +1000 mV for HI 8615L at Electrode input) and check display reading.
(see page 13).

PREPARATION PROCEDURE
Remove the protective cap. DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is normal with electrodes and they will disappear when rinsed
with water. During transport tiny bubbles of air may have formed inside the glass
bulb. The electrode cannot function properly under these conditions. These bubbles can be removed by "shaking down" the electrode as you would do with a glass thermometer.
If the bulb and/or junction are dry, soak the electrode in HI 70300 storage solution for at least one hour.

If the electrode does not respond to pH changes, the battery is run down and the electrode should be replaced.
MEASUREMENT
Rinse the electrode tip with distilled water. Immerse the tip (4 cm / 1½") in the sample and stir gently for
approx. 30 seconds. For a faster response and to avoid cross contamination of the samples,
rinse the electrode tip with a few drops of the solution to be tested, before taking measurements.
STORAGE
To minimize clogging and assuring a quick response time, the glass bulb and the junction should be kept moist and not allowed to dry out. Replace the solution in the protective cap with a few drops of
HI 70300
storage solution or, in its absence, filling solution (HI 7071
for single junction or HI 7082 for double junction electrodes). Follow the Preparation Procedure above before taking measurements.
Note: NEVER STORE THE ELECTRODE IN DISTILLED WATER OR DRY.
PERIODIC MAINTENANCE
Inspect the electrode and the cable. The cable used for connection to the meter must be intact and there must be no points of broken insulation on the cable or cracks on the electrode stem or bulb. Connectors must be perfectly clean and dry. If any scratches or cracks are present on the electrode body, replace the electrode. Rinse off any salt deposits with water.

The resistance of glass electrodes partially depends on the temperature. The lower the temperature, the higher the resistance. It takes more time for the reading to stabilize if the resistance is higher. In addition, the response time will suffer to a greater degree at temperatures below 25 °C (77 °F).
Since the resistance of the pH electrode is in the range of 50-200 Mohm, the current across the membrane is in the pico Ampere range. Large currents can disturb the calibration of the electrode for many hours. For these reasons high humidity environments, short circuits and static discharges are detrimental for a stable pH reading. The pH electrode's life also depends on the temperature. If constantly used at high temperatures, the electrode life is drastically reduced.

Alkaline Error
High concentrations of sodium ions interfere with readings in alkaline solutions. The pH at which the interference starts to be significant depends upon the composition of the glass. This interference is called alkaline error and causes the pH to be underestimated. Hanna's glass formulations have the indicated characteristics.

INSTALLATION PROCEDURE AND EXAMPLESINSTALLATION PROCEDURE AND EXAMPLES
The HI 8614 family and HI 8615 family transmitters may be wall mounted in any convenient location near the measurement point. To minimize thermal drift due to extreme temperature fluctuations during the measurement process, particularly if the measurement is conducted outdoors, it is best to protect the transmitter in an enclosed casing.
General Installation Procedure
For most industrial application involving long term monitoring and control, it is also recommended to use tank electrode holders (HI6050 or HI6051) to protect the pH electrode and the temperature probe from contamination by the test solution.
