CONDUCTIVITY MEASUREMENTS

Make sure that the instrument has been calibrated before taking

conductivity measurements (see page 8 for calibration procedure).

Connect the probe to the back of the meter and

switch the instrument on by pressing the ON/OFF

key. If possible, to minimize any EMC interfer-

ences, use plastic beakers for the solutions.

FOR HI8819:

••

• Immerse the probe in the solution submerging

the holes of the sleeve (0.5 cm below). Tap

the probe lightly on the bottom of the recipi-

ent to remove any air bubbles which may

have being trapped inside the sleeve.

••

• Take the temperature of the solution with a

CHECKTEMP or a glass thermometer.

••

• Press the COND/TEMP key to select tempera-

ture mode.

••

• Adjust the TEMPERATURE knob until the LCD

displays the temperature of the solution.

••

• Press the COND/TEMP key to select the con-

ductivity measurement range.

••

• If the display shows only a "1", there is an

over-range condition. Select the next higher

range.

••

• The conductivity reading displayed has been manually compen-

sated for temperature variations.

••

• After the measurement is completed, the in-

strument should be switched off by pressing

the ON/OFF key and the probe should be

cleaned (see page 15 for cleaning procedure).
