These instruments are in compliance with the directives.

PRELIMINARY EXAMINATION

Remove the instrument from the packing material and examine it carefully. If any damage has occurred during shipment, immediately notify your Dealer or the nearest Hanna Customer Service Center. Each meter is supplied with:

• Conductivity probe

• HI 7634D/1 for HI 86301 and HI 86303

• HI 7632D/1 for HI 86302 and HI 86304

• Calibration solution sachet (20 mL)

• HI 70031 (1413 μS/cm) for HI 86303

• HI 70039 (5.00 mS/cm) for HI 86304

• HI 70032 (1382 ppm) for HI 86301 & HI 86302

• Battery, screwdriver & instructions

Note: Conserve all packing material until the instrument has

been observed to function correctly. Any defective item must be returned in its original packing.

GENERAL DESCRIPTION

These EC and TDS portable meters have been designed for simplicity of use, and provide accurate measurements. Readings are automatically compensated for temperature variations, and the calibration is manually performed at one point through trimmer. The BEPS (Battery Error Prevention System) automatically switches the meter off when the battery level is too low to ensure reliable readings. The housing has been completely sealed against humidity, for use in any type of environment. The probe is easy to clean and requires little maintenance.

Choose the model with the measurement range that best fits your application:

• HI 86301 reads TDS from 0 to 1999 ppm (mg/L)

• HI 86302 reads TDS from 0.00 to 10.00 ppt (g/L)

• HI 86303 reads EC from 0 to 1999 μS/cm

• HI 86304 reads EC from 0.00 to 19.99 mS/cm

TAKING MEASUREMENTS

CALIBRATION

CE DECLARATION OF CONFORMITY

• Each meter is supplied complete with a 9V alkaline battery. Remove the battery compartment cover on the rear of the meter and install the battery while paying attention to the correct polarity (see also “Battery Replacement” section).

• Connect the probe to the DIN plug on the top of the meter, and switch the instrument on by pressing the ON/OFF button.

• Immerse the probe into the solution to be tested. For best accuracy, the probe should not touch or stand close to the vessel’s walls or bottom. If possible, use plastic beakers to minimize any EMC interference.

• Tap the probe gently on the bottom and shake it, to make sure no air bubbles have remained trapped inside.

• Allow the reading to stabilize. The LCD will show the EC or TDS value automatically compensated for temperature effects.

BATTERY REPLACEMENT

When the battery becomes weak the meters will display an additional blinking decimal point. When the low battery indicator appears, only a few hours of battery life are left.

In addition, these instruments are provided with BEPS (Battery Error Prevention System) that automatically turns the meter off when the battery level is too low to ensure reliable readings.

It is recommended to replace the battery immediately. Battery replacement must only take place in a nonhazardous

area using a 9V alkaline battery. Unscrew the three screws on

the rear of the meter, remove the battery compartment cover and replace the 9V battery with a new one.

Make sure the battery contacts are tight and secure before replacing the cover.

• Pour a small quantity of the proper calibration solution in a beaker (HI 7031 for HI 86303, HI 7032 for HI 86301 and HI 86302, HI 7039 for HI 86304). If possible, use plastic beakers to minimize any EMC interference.

• The calibration is a manual, 1-point procedure through trimmer. To access the calibration trimmer, remove the battery compartment cover on the rear of the meter.

• Turn the meter on and immerse the probe in the calibration solution, making sure that the metal pins are completely submerged and the probe body does not touch nor stand close to the side walls of the beaker.

• Tap the probe gently on the bottom and shake it, to make sure no air bubbles have remained trapped inside.

• Wait for a couple of minutes for thermal equilibrium to be reached and the temperature to be compensated, then adjust the calibration trimmer with the supplied screwdriver until the display shows the calibration solution value.

Calibration is now complete.

PROBE MAINTENANCE

It is recommended to clean the probe at least once a month, by following this procedure:

• Immerse the tip of the probe in the HI 7061 cleaning solution for half an hour.

• If a more thorough cleaning is required, brush the metal pins with very fine sandpaper.

• After cleaning, rinse the probe with tap water and recalibrate the instrument.

Recommendations for Users

Before using these products, make sure that they are entirely suitable for the environment in which it is used. Operation of these instruments in residential areas could cause unacceptable interferences to radio and TV equipment. Any variation introduced by the user to the supplied equipment may degrade the instruments’ EMC performance. To avoid electrical shock, do not use this instrument when voltage at the measurement surface exceeds 24 Vac or 60 Vdc. To avoid damage or burns, do not perform any measurement in microwave ovens.
