User Guide

With HI 8633 and HI 8734 press the COND/TEMP key (for

HI 8633) or TDS/TEMP (for HI 8734) to display the temperature

and adjust the temperature knob to that of the solution e.g. 20°C.

• Select the appropriate measurement range.

Note: If the display shows only a "1" on the

far left hand side, the meter is out of

range. Select the next (higher) range.

•

For HI 8733:

Adjust the TEMPERATURE COEFFICIENT

knob to 2% to compensate for the tem-

perature effect of average solutions (to

determine exact value for a particular so-

lution, see page 20).

•

For HI 8733 and HI 933000:

Wait for a couple of minutes for the temperature sensor to reach

thermal equilibrium with the sample before taking measure-

ments.

When the sample's temperature is lower than 20°C or higher

than 30°C, allow more time for the thermal equilibrium of the

system to be achieved.

• After the measurement has been completed, the instrument should

be switched off and the probe should be cleaned and dried (see

"Probe Maintenance" on page 21).
