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. 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 voltages at the measurement surface
exceed 24 Vac or 60 Vdc. To avoid damages or burns, do not perform any measurement in
microwave ovens.
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.
Each meter is supplied with:
• Mounting brackets
• Instruction manual
Note: Conserve all packing material until the instrument
has been observed to function correctly. Any defective
item must be returned in its original packing.

PRELIMINARY EXAMINATION
BL983322-0 and BL983322-1 are conductivity indicators
and controllers with a relay output designed for simplicity of
use in a wide range of applications.
Connections and wiring to probe, power supply and contacts
are made via the terminal blocks on the rear panel.
The probe is easy to clean and requires little maintenance.
Other features include: automatic temperature compensation
of readings, single point calibration, overtime control system,
multi-colour LED for indicating if the meter is in measure-
ment/dosing/alarm condition, possibility to set (Off-Auto-On
switch) dosing action mode.
Two models are available:
• BL 983322-0 powered at 12 Vdc
• BL 983322-1 powered at 115 or 230 Vac

REAR PANEL CONNECTIONS
Terminals #1: Probe
• Connect the HI 7634-00 probe by following the wires
colour indications.
Terminals #2: Power Supply
• Model BL983322-0: connect the 2 wires of a 12 Vdc
power adapter to the terminals +12 Vdc and GND.
• Model BL983322-1: connect a 3-wire power cable to the
terminals while paying attention to the correct earth (PE),
line (L) and neutral (N1 for 115 V or N2 for 230 V) contacts.
Terminals #3: Dosing Contact
• This contact drives the dosing system, accordingly to the
selected setpoint.
Note: The setpoint has a typical hysteresis value comparable
to the meter accuracy.
Terminals #4: Not Used Contact
Overtime system: jumper (#5) and trimmer (#6)
• This system allows the user to set a maximum dosing
period, by adjusting the rear trimmer from 5 (min) to
approx. 30 (max) minutes.
• When the set time is exceeded, any dosing action stops,
the LED indicator on the front panel will blink Red and the
LCD will show the “TIMEOUT” warning message. To exit
the overtime condition, set the OFF/Auto/ON switch to
“OFF” position, and then to “Auto” again.
• For disabling the overtime feature, simply remove the
jumper on the rear panel.
Note: The overtime system works only if the OFF/Auto/ON
switch is in “Auto” position.
OPERATING THE METER
Before proceeding make sure that:
• the meter has been calibrated;
• the setpoint value has been properly adjusted;
• all rear panel wiring and selections are correct;
• the Auto/OFF/ON switch is in the desired position.
Install or immerse the probe in the solution to be monitored,
then press the “MEAS” key (if necessary).
The LCD will show the EC (µS/cm) value. The LED indicator
will light up Green when the meter is in measurement mode
and dosing is not active, while will light up Orange/Yellow for
signaling that a dosing action is in progress.

OPERATIONS
CALIBRATION
To calibrate the meter, proceed as follows:
• ensure the meter is in measurement mode;
• use a solution with an EC value higher than 13 µS/cm
and immerse the probe;
• shake briefly and wait for reading to stabilize;
• adjust the “CAL” trimmer to read the solution EC value on
the LCD.
SETPOINT
Press the “SET” key: the display will show the default or
previously adjusted value, together with the “SET” indication.
Using a small screwdriver adjust the “SET” trimmer until the
desired setpoint value is displayed.
After 1 minute the meter automatically returns to the normal
mode; or press the “MEAS” key.
PROBE MAINTENANCE
To improve the 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.
ISTBL3322R3 04/05
All external cables connected to the rear panel
should end with cable lugs.
A circuit breaker (rated 6A max.) must be
connected in close proximity to the equip-
ment, and in a position easy to reach by the
operator, for disconnection of the instrument
and of all the devices connected to the relays.
