OPERATIONAL GUIDE TAKING PH MEASUREMENTS Connect the instrument to the 12VDC adapter (HI710005 or HI710006). Plug the adapter into the mains. Make sure that the instrument has been calibrated for pH before taking pH measurements (see page 18). For HI8519 only: ON • Connect the pH electrode to the meter and switch OFF the instrument on by pressing the ON/OFF key. • Immerse the electrode tip (4 cm/1½") into the sample and shake briefly. • Take the temperature of the solution with a ChecktempC or a

4 cm (1½") • In HI8417 the temperature reading is also displayed on the left LCD. °C pH Note: the electrode should be submerged approximately 4 cm (1½") into the solution. If the temperature probe is used, it should be located as close to the pH electrode as possible. If measurements are taken in different samples successively, it is recommended that the electrode is rinsed thoroughly for better condi- tioning and to eliminate cross-contamination of the sample. For the rinsing process, it is re

With the tempera- ture probe connected, the "°C" symbol is displayed continuously. • Use the UP or DOWN arrow keys to °C °C manually adjust the display reading to the value of the reference ther- mometer. TAKING TEMPERATURE MEASUREMENTS (NOT FOR HI 8519) • Taking a temperature measurement is very easy. • Turn the instrument ON and press the RANGE key RANGE (for HI8520 and HI8521 only) to get into tem- perature mode. • Make

For HI8417 and HI8521 • Connect the ORP electrode to the meter and submerge the tip (4 cm / 1½") into the sample to be tested. Note: ORP measurements are taken without temperature compensa- tion. pH pH RANGE • Press the pH/mV key (HI8417) or mV mV RANGE key (HI8521) once to enter the mV mode. • Allow a few minutes for the reading to stabilize. • The display will indicate the absolute mV mV value (positive or negative). • When values are less than ±400 mV, tenths of mV are dis- played; for values

4 cm (1½") PH CALIBRATION IMPORTANT The instrument's pH range should be re-calibrated: • When the meter is new. • Whenever the pH electrode is replaced. • At least once a month. • After use in aggressive chemicals. • After cleaning procedure and changing the reference electrolyte. • For greatest accuracy. INITIAL PREPARATION Pour small quantities (up to 4cm / 1½" level) of pH 7.01 (HI7007 or HI8007) and pH4.01 (HI7004 or HI8004) or pH 10.01 (HI7010 or HI8010) solution into clean beakers. If HI 7

Procedure: ON • Switch the instrument on after connecting the pH electrode and the temperature probe. • Immerse the pH electrode and the ATC probe into a neutral pH buffer solution (pH 7.01 for technical buffers, or pH 6.86 for NBS buffers). Shake briefly and wait 1-2 minutes for thermal equilibrium. CAL • Press the CAL key. The symbol "d1" will appear on the display. For calibration with technical buffers (pH 7.01), press CAL key again and "t1" will appear on the display. (Note: the "pH" symbol

• The meter automatically recognizes the buffer value and prompts for the second at "d2" or "t2" (= pH 4.01, acid) or "d3" or "t3" (pH 9.18 and pH10.01 respectively, alkaline). CON • Press the CON key to confirm the pH value. • The display will indicate the temperature compen- sated buffer value e.g. if the temperature is at 25°C, the display will show "pH 4.01" or "10.01" or "pH 9.18", depending on the solution being used. If the temperature is at 20°C, the display will show respectively "pH 4.
