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 in-

strument has been observed to function correctly. Any
defective item must be returned in its original pack­ing.

GENERAL DESCRIPTION

HI 983327-0, HI 983327-1 and HI 98332700 are
conductivity indicators and controllers with a relay output
designed for simplicity of use in a wide range of applica­tions.

HI 98332700 is provided with a DC/DC converter which
isolates the measure system from the external power supply.
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 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 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.

Note: the power input is internally protected by a 400 mA fuse

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

OPERATIONAL GUIDE

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

to temperature compensation.
The “ALARM” LED will light up when the alarm contact is

losed, 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 7039 (5.00 mS/cm) calibration
solution.

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

until the meter displays “5.00” 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.
