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).
