OPERATIONAL GUIDE INITIAL PREPARATION The meter is supplied complete with batteries. Remove the back cover, unwrap the batteries and install them while paying attention to polarity. To prepare the instrument for use connect the pH electrode and the temperature probe to the BNC and temperature sockets on the top of the instrument. The temperature probe can be used independently to take temperature measurements, or it can be used in conjunction with the pH electrode to utilize the meter's ATC capability.
meter to measure the pH accurately, temperature must be taken in consideration. If the sample temperature is quite different from the temperature at which the pH electrode was kept, allow a few minutes for a perfect thermal equilibrium between them. To use the meter's Automatic Temperature Compensation feature, submerge the temperature probe into the sample as close to the electrode as possible and wait for a couple of minutes.
p H CALIBRATION It is recommended to calibrate the instrument frequently, especially if high accuracy is required. The instrument should be recalibrated for pH: a) Whenever the pH electrode or temperature probe is replaced. b) At least once a month. c) After testing aggressive chemicals. d) If greatest accuracy is required. e) Whenever the batteries have been replaced. PREPARATION 04 70 HI Pour small quantities of pH 7.01 and pH 4.01 solution into two clean beakers.
the Standard 7.01 or the NIST 6.86 are the most appropriate for this purpose even though both meters can be calibrated with any of the 5 memorized calibration solutions. • Immerse the pH electrode into a pH buffer solution (e.g. pH 6.86) and stir gently. Note: the electrode should be submerged approximately 4 cm (1½") into the solution. With the temperature probe located as close to it as possible. • Press the CAL key. The "CAL" and " 1" indicators will be displayed.
• Press the CAL key and the calibration process is ended with only the offset of the meter calibrated. For best accuracy however, do not press CAL and proceed with a two-point calibration. TWO-POINT CALIBRATION After calibrating at 6.86 or 7.01 pH (see above), for the second buffer use pH 4.01 if you are going to measure acidic samples, and pH 9.18 or pH 10.01 if you are going to measure alkaline solutions.
p H VALUES AT VARIOUS TEMPERATURES Temperature has an effect on pH. The calibration buffer solutions are effected by temperature changes to a lesser degree than normal solutions. For manual temperature calibration please refer to the following chart. For instance, if the buffer temperature is 25°C, the display should show pH 4.01, 7.01 or 10.01 at pH 4, 7 or 10 buffers, respectively. At 20°C, the display should show pH 4.00, 7.03 or 10.06. The meter reading at 50°C will then be 4.06, 6.98 or 9.82.

ELECTRODE CONDITIONING & MAINTENANCE * Not present in gel electrodes. PREPARATION 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 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 a 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 General Soak in Hanna HI 7061 or HI 8061 General Cleaning Solution for approximately ½ hour. Removal of films, dirt or deposits on the membrane/junction: - Protein Soak in Hanna HI 7073 or HI 8073 Protein Cleaning Solution for 15 minutes. - Inorganic Soak in Hanna HI 7074 or HI 8074 Inorganic Cleaning Solution for 15 minutes. - Oil/grease Rinse with Hanna HI 7077 or HI 8077 Oil and Fat Cleaning Solution.
BATTERY REPLACEMENT & AUTO-OFF If the batteries become weak the meter will display "LOW BAT". The warning message is to alert the user that the display will be shut-off after about 5 hours of use. After that, the meter shuts down the display, preventing the taking of erroneous measurements due to low voltage. Battery replacement must only take place in a non hazardous area using the battery types specified in this instruction manual.
