TEMPERATURE COEFFICIENT
FOR HI8820:
• •• •• 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 recipient
to remove any air bubbles which may have
being trapped inside the sleeve.
• •• •• If the display shows only a "1", there is an
over-range condition. Select the next higher
range.
• •• •• Adjust the "TEMPERATURE COEFFICIENT" knob
to the value of the solution. See page 15 for
the procedure to select the correct coefficient
value.
• •• •• Before taking any measurement allow a few minutes for the
reading to stabilize. As soon as the thermal equilibrium is reached
(3 or 4 minutes) the reading stops drifting.
• The conductivity reading displayed has been automatically com-
pensated for temperature variations (after 2 or 3 minutes).
• •• •• 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).
