GENERAL DESCRIPTION

HI 983313-0 and HI 983313-1 are conductivity indicators
and controllers with a relay output designed for simplicity of
use in a wide range of applications.

The two models are panel mounted with membrane key­pads on the front panel and an easy-to-read LCD display.

Both meters automatically compensate for the temperature
variation.

The probe is easy to clean and requires little maintenance.
Measurements are highly accurate and the meters can be

calibrated at one point.
Power supply, wiring and selection are made via the plug-

in terminal blocks on the rear panel.
LED indicators on the front panel identify whether the

controller is in set or measurement mode and if alarm is
active.

Recommendations for Users
Before using these products, make sure that they are entirely suitable

for the environment in which they are used. Operation of these instru­ments in residential areas could cause unacceptable interferences to
radio and TV equipment. The metal band at the end of the probe is
sensitive to electrostatic discharges. Avoid touching this metal band at
all times. During operation, ESD wrist straps should be worn to avoid
possible damage to the probe by electrostatic discharges. Any variation
introduced by the user to the supplied equipment may degrade the
instrument’s EMC performance.

To avoid electrical shock, do not use these instruments when voltage at
the measurement surface exceeds 24 VAC or 60 VDC. Use plastic
beakers to minimize any EMC interferences.

To avoid damage or burns, do not perform any measurement in micro­wave ovens.

to connect the shield (P5) to avoid any interference.

OPERATIONAL GUIDE

POWER CONNECTION

HI 983313-0

Connect a 2-wire power cable to the terminal strip while
paying attention to the correct positive and negative polari­ties (12 VDC).

HI 983313-1

Connect a 3-wire power cable to the terminal strip while
paying attention to the correct earth, neutral and line
contacts (115/230 VAC).

ALARM CONTACT

Use this contact (maximum 5A, 240VAC, 30VDC) for connec­tion to an alarm or dosing system. The unit acts as a switch
to control an external device.

Notes:

• All external cables connected to the rear panel should
end with wire lugs.

• It is recommended to cover the unused terminals with
insulating tape.

• At start up the meter needs a few seconds to stabilize.
Wait until a stable reading is displayed.

OPERATING THE METER

All operations can be controlled via front panel keys and
trimmers.

“SET” and “MEAS” LEDs light up to indicate which is the
operating function.

Make sure that the meter is calibrated and the Setpoint is
properly selected before performing any measurement.

Attach the probe to the meter. Install the probe in the
fittings or immerse it in the solution to be monitored, while
making sure that metal pins are completely submerged.
Press the “MEAS” key.

The LCD will show the conductivity value of the solution in
µS/cm unit. Any initial variation on readings may be due
to temperature compensation.

The “ALARM” LED will light up when the alarm contact is
closed, to indicate an EC value higher than selected setpoint.

CALIBRATION

Make sure the meter is in the measurement mode (the
“MEAS” LED lights on).

Immerse the probe in HI 7031 (1413 µS/cm) calibration

solution.

Shake briefly and wait for reading to stabilize.
Using a small screwdriver adjust the calibration trimmer

until the meter displays “1413” on the LCD.

SETPOINT

Press the “SET” key. The display will show the default or
previously adjusted value for the setpoint.

Using a small screwdriver, adjust the “SET” trimmer until
the required limit value is displayed.

PROBE MAINTENANCE

To improve probe performance and prolong its life, it is
recommended to clean it regularly.

• Immerse the tip of the probe in HI 7061 Cleaning
Solution at least for one 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 meter.

• When not in use, clean the probe before storing it.
