OPERATIONAL GUIDE POWER CONNECTION • The pH is displayed on the primary LCD and the temperature on the secondary LCD. pH Plug the 12 VDC adapter into the power supply socket. Notes: • These instruments use non volatile memory to retain the pH, mV, temperature calibrations and all other settings, even when unplugged. • Make sure a fuse protects the main line.
• The instrument displays the mV reading on the primary LCD and the temperature on the secondary LCD. C mV • If the reading is out of range, “----” will be displayed on the LCD. TEMPERATURE MEASUREMENTS Connect the HI 7669/2W temperature probe to the appropriate socket and turn the instrument on. Immerse the temperature probe into the sample and allow the reading on the secondary LCD to stabilize. MEMORY FUNCTION Press and hold down MEM.
• When the reading is stable and close to the selected buffer, “READY” tag will appear and “CFM” tag will blink. • Press CFM to confirm calibration. • The calibrated value is then displayed on the primary LCD and the secondary LCD will display CFM the second expected buffer value. pH CAL BUFFER pH BUF 2 Note: The instruments will automatically skip the buffer used for the first point. It also skips 6.86 if 7.01 buffer was used and viceversa. Likewise, it will skip 9.18 if 10.
TEMPERATURE CALIBRATION (for technical personnel only) All the instruments are factory calibrated for temperature. Hanna’s 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.
m V CALIBRATION ((pp H 213 only only)) (for technical personnel only) PC INTERFACE (p H 212 & p H 213 only (pH only)) 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.
SENDING COMMANDS FROM PC It is also possible to remotely control the instrument with any terminal program. Use HI 920010 cable to connect the instrument to a PC, start the terminal program and set the communication options as follows: 8, N, 1, no flow control. COMMAND TYPES To send a command to the instrument, follow the next scheme: This line makes the computer send a Data Link Escape character, the command expressed as a 3-character sequence and a CR character.
ELECTRODE CONDITIONING & MAINTENANCE 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.
CLEANING PROCEDURE TROUBLESHOOTING GUIDE • 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. Soak in Hanna HI 7074 Inorganic Cleaning • Inorganic Solution for 15 minutes. • Oil/grease Rinse with Hanna HI 7077 or HI 8077 Oil and Fat Cleaning Solution.
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 °C. Since the resistance of the pH electrode is in the range of 50-200 Mohms, the current across the membrane is in the pico Ampere range.
