If the bulb and/or junction are dry, soak the electrode in HI 70300 Storage Solution for at least one hour. For refillable electrodes: If the refill solution (electrolyte) is more than 2½ cm (1") below the fill hole, add HI 7082 3.5M KCl Electrolyte Solution for double junction or HI 7071 3.5M KCl+AgCl Electrolyte Solution for single junction electrodes. For AmpHel® electrodes: If the electrode does not respond to pH changes, the battery is run down and the electrode should be replaced.

Turn the rotary knob to the °C position to display temperature setting on the LCD.
TEMPERATURE CALIBRATION mV OUTPUT It is possible to attach the HI 8915 to a recorder or plotter using the mV output sockets. pH, mV and °C readings can be transmitted through the output sockets at a voltage that proportionally matches the displayed value. For example, when the meter reads 2.00, 7.00 or 12.00 pH, it emits a 200, 700 or 1200 mV signal, respectively. This makes it unnecessary to use conversion tables and charts.
compensate for it (HI 8424 and HI 9622 only). In this case, the temperature probe must be disconnected. HI 8014 provides only for manual compensation. With HI 8314 and HI 8915 when the temperature probe is disconnected, the pH reading will be compensated at 25°C. If a different compensation is required, reattach the probe. • Use the UP and DOWN keys to set the temperature manually to the above value.
pH CAL To measure the mV of a sample submerge the ORP electrode tip (4 cm/1½") in the sample to be tested. Allow a few minutes for the readings to stabilize. Also, see page 42 for more information about REDOX measurements. Note (for HI 8424 and HI 9622): the resolution is 0.1 mV for values within the ±400mV range. 4 cm (1½") • The meter will request pH 4.01 or 10.01 buffer by showing "Er-4".
HOLD FUNCTION (HI 8915 ONLY) • Press RANGE to display pH measurement. The hold function is activated by the HOLD key. The measured value is frozen on the display when this key is pressed. "S" symbol will appear on the display to indicate the holding (storage) mode. Press the HOLD key again to return to regular operational mode. • Press CAL to start calibration and to display the last calibration date again.
• If the ON/OFF key is pressed at this point, the calibration process will end with only the offset (one-point) calibration. For best accuracy, however, it is recommended that a two-point calibration is performed. • The LCD will now blink "4.01 ∆". pH 10.01 can be selected by pressing the CAL key. ∆ • Rinse with pH 4.01 (or pH 10.01) buffer solution (2nd calibration point). • Dip the electrode into a pH 4.01 (or pH 10.01) buffer solution.

• Remove the protective cap from the electrode, rinse the tip of the electrode with some pH 7.01 solution, then immerse the pH electrode and temperature probe in a pH 7.01 buffer solution. Stir gently and wait a couple of minutes for thermal equilibrium. Note: the electrode should be submerged approximately 4 cm (1½") into the solution. The temperature probe should be located close to the pH electrode. • Press °C to display the temperature of the buffer (e.g. 20.0°C).
PROCEDURE FOR HI 8424 ON • Press RANGE to display pH measurement. • Rinse the electrode and temperature probe before immersing them into pH 4.01 or pH 10.01 calibration buffer. Stir gently and wait for thermal equilibrium. • The symbol "E5" should disappear and a temperature compensated buffer value starts blinking. • Wait until the pH symbol stops flashing.
