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).
