GENERAL DESCRIPTION
HI 983319-0 and HI 983319-1 are conductivity indicators
and controllers with a relay output designed for simplicity of
use in a wide range of applications.
The models are panel mounted with membrane keypads on
the front panel and an easy-to-read LCD display.
All the meters automatically compensate for temperature
variations. 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 plugin 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.

12 VDC 115/230 VAC
3. Probe Connection: follow the above diagram and connect the
colored wires of probe cable as indicated. It is recommended
to connect the shield (P5) to avoid any interference.
OPERATIONAL GUIDE
POWER CONNECTION
HI 983319-0
Connect a 2-wire power cable to the terminal strip while
paying attention to the correct positive and negative polarities (12 VDC).
HI 983319-1
Connect a 3-wire power cable to the terminal strip while
paying attention to the correct earth, neutral and line
contacts (115/230 VAC).
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.
Press the “MEAS” key.
The LCD will show the TDS value of the solution in ppm 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 a TDS value lower 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 “919” ppm.
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.

2.Alarm Contact: A1, A2.
This contact acts as a switch for the power. The contact
has to be protected outside by the user.
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.
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.
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.
