Accessories needed:

• Use any calibration solution within the meter's range. The

solution should ideally be close to the samples being mea-

sured. Use for example HI 7030 or HI 8030, 12880 µS/cm

(=12.88 mS/cm) conductivity solution for HI 8033, HI 8633,

HI 8733 and HI 933000 and HI 7032, 1382 mg/L

(=2764 µS/cm) TDS solution for HI 8734

• ChecktempC or an accurate thermometer with 0.1°C resolution

(not necessary for HI 8733 and HI 933000)

• a small screwdriver.

PROCEDURE FOR HI 8033

• Pour sufficient quantity of a conductivity

calibration solution (e.g. HI 7030/

HI 8030) into a beaker to cover the holes

on the probe. If possible, use plastic bea-

kers to minimize any EMC interference.

• Immerse the conductivity probe, making

sure that holes are completely submerged,

and the ChecktempC in the solution.

• Wait for a couple of minutes for thermal

equilibrium to be reached.

• Tap the probe on the bottom, then shake it while rotating to

make sure no air bubbles remain trapped in the sleeve.

• Record the temperature of the HI 7030/HI 8030 calibration

solution from the ChecktempC (e.g. 18°C).

• Turn the °C knob to 18°C.

• Turn the rotary knob to select 19990 µS/cm

range.

• Turn the k% calibration knob until the display shows the conduc-

tivity reading at 25°C (see the conductivity vs. temperature chart

on page 18). E.g. @ 25°C, 12880 µS/cm = 12.88 mS/cm.

• All subsequent measurements will be compensated to 25°C (77°F).

If you prefer to standardize the temperature compensation to

20°C (68°F) rather than 25°C (77°F), leave the °C knob at 18°C

(if the temperature of your solution is 18°C), adjust the trimmer

to read "11.67 mS" (see the conductivity vs. temperature chart at

page 18). All subsequent measurements will be compensated to

20°C.

• The calibration is now complete and the instrument is ready for

use.

The instrument should be re-calibrated at least once a month, or

when the probe or battery is changed.

Note: For more accurate results, it is advisable to use a calibration

solution close to the range to be measured. See the accessories

section on page 23 for a wide selection of conductivity solu-

tions.

PROCEDURE FOR HI 8633

• Pour sufficient quantity of a conductivity

calibration solution (e.g. HI 7030/

HI 8030) into a beaker to cover the holes

on the probe. If possible, use plastic bea-

kers to minimize any EMC interference.

• Immerse the conductivity probe, making

sure that holes are completely submerged,

and the ChecktempC in the solution.

• Wait for a couple of minutes for thermal

equilibrium to be reached.

• Tap the probe on the bottom, then shake it while rotating to make

sure no air bubbles remain trapped in the sleeve.

• Record the temperature of the HI 7030/HI 8030 buffer solution

from the ChecktempC (e.g. 18°C).

• Switch the instrument on by pressing ON/OFF.

• Press COND/TEMP to display the temperature.

• Adjust the TEMPERATURE knob to display 18°C.
