• Each meter is supplied complete with a 9V battery. Slide off the
battery compartment cover on the back of the meter (see page 22).
Install the battery while paying attention to its polarity.
• Connect the probe to the meter securely by aligning the pins with
the socket and pushing the plug in.
With HI 933000, tighten the threaded ring.
• Make sure that the meter has been calibrated before taking any
measurements (see page 11 for calibration procedure).
• Immerse the conductivity probe into the
sample, with the holes on the shaft com-
pletely submerged.
If possible, use plastic beakers or con-
tainers to minimize any EMC interference.
• Tap the probe lightly on the bottom of the beaker to remove any
air bubbles which may be trapped inside the PVC sleeve.
• Turn the instrument on by pressing the
ON/OFF key or by setting the rotary switch
(for HI 8033 only) to the desired mea-
surement range.
•
For HI 8033, HI 8633 and HI 8734 only:
Take the temperature of the solution with
a ChecktempC or an accurate thermom-
eter.
With HI 8033 set the temperature knob to
the measured value e.g. 20°C.

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).
