GENERAL DESCRIPTION

HI983318-0 and HI983318-1 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 compensates for the temperature variation
automatically. 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.

OPERATIONAL GUIDE

POWER CONNECTION

HI 983318-0

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

HI 983318-1

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.

ALARM CONTACT

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

OPERATING THE METER

All operations are via the 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 he LCD will show the TDS value of the solution in ppt
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 higher than selected setpoint.
sample.

When the alarm contact is closed, the "ALARM" LED will be
lit.

CALIBRATION

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

Immerse the probe in HI7038 (6,44 ppt) calibration solu­tion or another solution with a known g/L value.

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

until the meter displays “6.44” ppt or any other value
accordingly to the calibration solution. All future measure-

ments will be compensated for temperature with reference to
25ºC (77ºF).

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 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 away.
