OPERATIONAL GUIDE

POWER CONNECTION

HI 983322-0 and HI 98332200

HI 983322-0 and HI 98332200
Connect a 2-wire power cable to the terminal strip while
paying attention to the correct positive and negative con-
tacts (12 VDC).

HI 983322-1

HI 983322-1
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:

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, 30VDC) for connec-
tion 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.

Note

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.

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.

Press the “MEAS” key.
The LCD will show the conductivity value of the solution in
µS/cm unit. Any initial variation on readings may be due
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

This meter is factory calibrated.
If re-calibration becomes necessary, a calibration solution
has to be prepared with the help of HI 9033 EC-meter (or
similar). Recommended conductivity value of calibration solu-
tion should be around 13 µS/cm.
Make sure the meter is in the measurement mode (the
“MEAS” LED lights on).
Immerse the probe in the prepared solution.
Shake briefly and wait for reading to stabilize.
Using a small screwdriver adjust the calibration trimmer
until the meter displays the required EC value 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.
