OPERATIONAL GUIDE INITIAL PREPARATION The instrument is supplied complete with rechargeable batteries. Proceed with a complete charging process before starting (see page 58). To prepare the instrument for field measurements close the serial communication socket and all unused connector sockets with proper stopper (to ensure waterproof protection) (HI 98183/4/5 only). Use the holed temperature rubber cork for the temperature socket when temperature probe is connected (HI 98183/4/5 only).
Allow for the electrode to adjust and reading to stabilize (hourglass symbol turns off). On the pH screen are displayed: • pH reading with the selected resolution. • Temperature reading in the selected unit (ºC or ºF). • Temperature compensation mode (MTC - manual, ATC - automatic). While in MTC mode the indicate that the temperature can be manually changed using ARROW keys. • Electrode condition during the calibration day. • The buffers used in last pH calibration (if feature is enabled in SETUP).
ORP MEASUREMENTS (not for HI 98180) To perform ORP measurements, connect an optional ORP electrode (see “Accessories“ section) to the instrument and turn it ON. If necessary, enter the mV mode by pressing RANGE until the display changes to mV. Submerge the ORP electrode tip (4cm/1½”) into the sample to be tested and wait a few seconds for the reading to stabilize. Measurements are displayed with 0.1 mV resolution.
Enter the ISE mode by pressing RANGE until the display changes to ISE range. Submerge the ISE electrode tip (4cm/1½”) into the sample to be tested and wait a few seconds for the reading to stabilize. The ISE reading will be displayed along with the current temperature reading. The “ATC” (or “MTC”) message is turned off because ppm readings are not temperature compensated.
p H CALIBRATION It is recommended to calibrate the instrument frequently, especially if high accuracy is required. The pH range should be recalibrated: • Whenever the pH electrode is replaced. • At least once a week. • After testing aggressive chemicals. • When calibration alarm time out is expired - “CAL DUE” blinks (if feature is enabled in SETUP). • If “Outside Cal Range” message blinks during pH measurement (the measurement range is not covered by current calibration, if feature is enabled in SETUP).
• Press CAL. The instrument will display the measured pH, the LCD first expected buffer and the temperature reading. • 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, CFM functional key is displayed. • Press CFM to confirm first point. • The calibrated value and the second expected buffer value is then displayed on the LCD.
• When the reading is stable and close to the selected buffer, the CFM functional key is displayed. • Press CFM to confirm calibration. • The calibrated value and the third expected buffer value will be displayed. • After the second calibration point is confirmed, immerse the pH electrode and the temperature probe approximately 4 cm (1½”) into the third buffer solution and stir gently. The temperature probe should be close to the pH electrode.
• After the third calibration point is confirmed, immerse the pH electrode and the temperature probe approximately 4 cm (1½”) into the fourth buffer solution and stir gently. The temperature probe should be close to the pH electrode. • 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 CFM functional key is displayed. • Press CFM to confirm calibration.

BATTERIES RECHARGING/REPLACEMENT The instrument is ready with rechargeable batteries inside. First time you start working with the instrument or when the rechargeable batteries are changed with new ones, perform the following procedure: • Work with the instrument until the rechargeable batteries are fully discharged • Perform a complete charging cycle (about 16hours). Repeat this procedure 3 times.
To recharge the rechargeable batteries, follow the next steps: • Connect the 12VDC power adapter to the main line and to the main line of the battery recharger. The front LED will turn ON. • Place the instrument in the battery recharger case. A charging animation will be displayed if the battery capacity is less than 100 %. • The complete charging process takes about 16 hours.
TEMPERATURE CORRELATION FOR p H 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 (77 ºF). 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.
ELECTRODE CONDITIONING & MAINTENANCE Not present in gel electrodes. PREPARATION PROCEDURE Remove the electrode 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.
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 run down and the electrode should be replaced.
Follow the Storage Procedure above. pH CLEANING PROCEDURE • General 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. Rinse with Hanna HI 7077 or HI 8077 Oil and Fat • Oil/grease Cleaning Solution.
