OPERATIONAL GUIDE POWER CONNECTION Plug the 12 VDC adapter into the power supply socket. Note: These instruments use non volatile memory to retain the pH, mV, temperature calibrations and all other settings, even when unplugged. Note: Make sure a fuse protects the main line. ELECTRODE AND PROBE CONNECTIONS For pH or ORP measurements connect an electrode with internal reference to the BNC connector on the back of the instrument.
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. In order to measure the pH accurately, the temperature effect must be compensated for.
RELATIVE mV MEASUREMENTS (HI 111 and HI 113) Press RANGE until rEL message will be displayed on the secondary LCD line for about one second and mV tag will blink. After one second the temperature will be displayed on the secondary LCD. mV The reading displayed by the instrument is equal to the difference between the current mV input value and relative mV offset established in the relative mV calibration.
PREPARATION Pour small quantities of the buffer solutions into clean beakers. If possible, use plastic or glass beakers 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 first buffer and pH 4.01 or 1.68 (HI 112, HI 113) as second buffer. If you are measuring in the alkaline range, use pH 7.01 or 6.
THREE- (HI 110, HI 111) / FIVE-POINT (HI 112, HI 113) CALIBRATION Immerse the pH electrode and the temperature probe approximately 4 cm (1½) into a buffer solution and stir gently. The temperature probe should be close to the pH electrode. Press CAL. The CAL and tags will appear and the 7.01 buffer will be displayed on the secondary LCD. BUF CAL pH BUFFER pH 1 BUF If necessary, press the ARROW keys to select a different buffer value.
If necessary, press the ARROW keys to select a different buffer value. The tag will blink on the LCD until the reading is stable. When the reading is stable and close to the selected buffer, the READY tag will be displayed and the CFM tag will blink. Press CFM to confirm calibration. If the fifth calibration point is reached, the instrument stores the calibration value and returns to normal measurement mode, or else it goes to the next calibration point.
To clear calibration parameters for all uncalibrated buffers starting with current buffer, press and hold down CFM, then press CAL. If this procedure is performed while calibrating in the first calibration point, the instrument returns to measurement mode, else calibration can be continued from the current point. Press RANGE (SEL for HI 110) to toggle between pH buffer and temperature reading (HI 110, HI 111).
GOOD LABORATORY PRACTICE (GLP) GLP is a set of functions that allows storage and retrieval of data regarding the maintenance and status of the electrode. All data regarding the last calibration (one, two, three, four or five-point) is stored for the user to review when necessary. This data includes the following: calibration time stamp, offset (mV), average of slope (%), calibration buffers and the time until a new calibration is required.
The pH calibration buffers in calibrating order. The first pH calibration buffer: CAL pH BUFFER pH BUF The second pH calibration buffer: CAL pH BUFFER pH BUF The third pH calibration buffer: CAL pH BUFFER pH BUF Note: For HI 112 and HI 113, the fourth and the fifth calibration buffers are also displayed in GLP. The OLd message displayed beside the pH value means that this buffer was not used during last calibration.
or the number of days until the calibration alarm will be displayed. or if expired (7 days ago). INTV CAL The instrument ID. Note: Press GLP at any moment and the instruments will return to measurement mode. If calibration has not been performed, the instruments display no CAL message blinking.
CALIBRATION ALARM TIME-OUT SET Press CAL when the calibration time-out is displayed. Calibration time-out (OFF or 1 to 7 days) will start blinking. INTV CAL Press the ARROW keys to change the calibration time-out value. Press CFM to save the modified calibration time-out value. Press CAL to escape without saving. FIRST CUSTOM BUFFER SET Press CAL when custom buffer 1 is displayed. The custom buffer (disabled no cb1 or 0 to 16 pH) will start blinking.
INSTRUMENT ID PARAMETER SET (HI 112, HI 113 only) Press CAL when the instrument ID is displayed. The instrument ID (0000 to 9999) will start blinking. Press the ARROW keys to change the instrument ID value. Press CFM to save the modified instrument ID value. Press CAL to escape without saving. CURRENT TIME SET Press CAL when the current time is displayed. The hour will start blinking. TIME Press the ARROW keys to change the hour. Press RANGE (SEL for HI 110). The minutes will start blinking.
Press RANGE. The day will start blinking. DATE Press the ARROW keys to change the day. Press CFM to save the modified value. Press CAL to escape without saving. BEEP STATUS SET Press CAL when the beep status is displayed. Beep status (On or OFF) will start blinking. Press the ARROW keys to change the beep status (On or OFF). Press CFM to save the modified beep status. Press CAL to escape without saving. BAUD RATE SET (HI 112, HI 113 only) Press CAL when the baud rate is displayed.
TEMPERATURE CALIBRATION (for technical personnel only) All the instruments are factory calibrated for temperature. Hannas temperature probes are interchangeable and no temperature calibration is needed when they are replaced. If the temperature measurements are inaccurate, temperature recalibration should be performed. For an accurate recalibration, contact your dealer or the nearest Hanna Customer Service Center, or follow the instructions bellow.
Use the ARROW keys to set the reading on the secondary LCD to that of the hot water. C C When the reading is stable and close to the selected calibration point, READY tag will appear and CFM tag will blink. Press CFM to confirm. The instrument returns to measurement mode. Note: If the reading is not close to the selected calibration point, WRONG tag will blink. Change the temperature probe and restart calibration.
mV CALIBRATION (for technical personnel only) All the instruments are factory calibrated for mV. Hannas ORP electrodes are interchangeable and no mV calibration is needed when they are replaced. If the mV measurements are inaccurate, mV recalibration should be performed. For an accurate recalibration, contact your dealer or the nearest Hanna Customer Service Center, or follow the instructions below. A two or three-point calibration can be performed at 0.0 mV, 600.0 mV and 1800.0 mV.
RELATIVE mV CALIBRATION (HI 111 AND HI 113) Press CAL when the instrument is in RELATIVE mV measurement mode. The mV and tags will blink. Absolute mV is displayed on the primary LCD and AbS message is displayed on the secondary LCD. When the absolute reading is stable and in measurement range, the instrument asks for confirmation. If the reading is out of range, WRONG tag will be displayed. Press CFM to confirm the absolute value. The instrument will display 0.
PC INTERFACE (HI 112 AND HI 113) Data transmission from the instrument to the PC can be done with the HI 92000 Windows® compatible software (optional). HI 92000 also offers graphing and on-line help feature. Data can be exported to the most popular spreadsheet programs for further analysis. To connect your instrument to a PC, use the optional Hanna HI 920010 cable connector.

ELECTRODE CONDITIONING & MAINTENANCE PREPARATION PROCEDURE Remove the protective cap of the pH electrode. DO NOT BE ALARMED IF SALT DEPOSITS ARE PRESENT. This is normal with electrodes. They will disappear when rinsed with water. During transport, tiny bubbles of air may form inside the glass bulb affecting proper functioning of the electrode. These bubbles can be removed by shaking down the electrode as you would do with a glass thermometer.
For refillable electrodes: If the filling solution (electrolyte) is more than 2½ cm (1) below the fill hole, add HI 7082 or HI 8082 3.5M KCl Electrolyte Solution for double junction or HI 7071 or HI 8071 3.5M KCl+AgCl Electrolyte Solution for single junction electrodes. For faster response, unscrew the fill hole screw during measurements. For AMPHEL ® electrodes: If the electrode does not respond to pH changes, the battery is run down and the electrode should be replaced.
CLEANING PROCEDURE Soak in Hanna HI 7061 or HI 8061 General Cleaning Solution for approximately ½ hour. Protein Soak in Hanna HI 7073 or HI 8073 Protein Cleaning Solution for 15 minutes. Inorganic Soak in Hanna HI 7074 Inorganic Cleaning Solution for 15 minutes. Oil/grease Rinse with Hanna HI 7077 or HI 8077 Oil and Fat Cleaning Solution.
TROUBLESHOOTING GUIDE SYMPTOMS Slow reponse/excessive drift. PROBL E M D irty pH electrode. Readings fluctuate up Clogged/dirty junction. and down (noise). L ow electrolyte level (refillable electrodes only). Out of range in the mV scale. D ry membrane/junction. The meter does not accept the buffer solution for calibration. Out of order pH electrode. If the display shows: "pH" and " -2.00" or "16.00" blinking.
TEMPERATURE CORRELATION FOR pH SENSITIVE GLASS 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 ºC. 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.
