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 electro-

static discharges. Avoid touching this metal band at all times. During op-

eration, 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 mini-

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

Dear Customer,
Thank you for choosing a Hanna product. This manual will
provide you with the necessary information for the correct
operation of the meter. Please read it carefully before using

the meter. If you need additional technical information, do
not hesitate to e-mail us at [e-mail].

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.

The meter is supplied with:

• Instruction manual;

• Mounting brackets.
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

HI 983324-0 and HI 983324-1 are conductivity indicators
and controllers with a relay output designed for simplicity of
use in a wide range of industrial 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 reading mode and if alarm is active.

POWER CONNECTION

HI 983324-0

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

HI 983324-1

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

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

CALIBRATION

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

Immerse the probe in

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

until the meter displays “42” ppm.

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 2A, 220V) 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.
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.

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.
