PRELIMINARY EXAMINATION
Remove the instrument from the packing material and examine it carefully to make sure that no damage has occurred during shipping. If there is any noticeable damage, notify your Dealer or the nearest Hanna office immediately.
Each meter is supplied with:
•Conductivity probe with DIN connector and 1 m (3.3') cable:
•HI 76301D for HI 8633 and HI 8734
•HI 76302W for HI 8733
•Calibration solution sachet
•Screwdriver, 1 x 9V battery and instruction manual
Note: Save all packing materials until you are sure that the instrument functions correctly. Any damaged or defective item must be returned in its original packing materials together with the supplied accessories.
GENERAL DESCRIPTION
HI 8633 and HI 8733 have been designed specifically for use in the areas of production and quality control. It is often necessary to test samples with different concentrations ranging from deionized water to brine.
Both models can be manually calibrated at 1 point.
The HI 8733, with a built-in temperature sensor and Automatic Temperature Compensation, is the perfect instrument for measuring samples with fluctuating temperature.
HI 8734 has been specially designed for the water conditioning industry, particularly in the softening, demineralization, reverse osmosis and drinking water applications.
Three ranges of measurement assure the highest accuracy possible. In addition, Manual Temperature Compensation is possible through a knob on the front panel.
The ratio between conductivity and TDS is factory set at 0.5. Moreover, the 4-ring potentiometric probes supplied with the meters are made of rugged PVC - ideal for indoor, as well as outdoor measurements.

OPERATIONAL GUIDE
•Each meter is supplied complete with a 9V battery. Remove the battery compartment cover on the back of the meter (see page 16). 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.
•Make sure that the meter has been calibrated before taking any measurements (see "Calibration" section).
•Immerse the conductivity probe into the sample, with the holes on the shaft completely submerged.
If possible, use plastic beakers or containers 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.
°C • For HI 8633 and HI 8734: 
Take the temperature of the solution with a ChecktempC or another accurate
thermometer.
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.
