OPERATIONAL GUIDE

POWER CONNECTION

HI 983315-0 and HI 98331500

HI 983315-0 and HI 98331500
Connect a 2-wire power cable to the terminal strip while
paying attention to the correct positive and negative polari-
ties (12 VDC).
HI 983315-1

HI 983315-1

HI 983315-1
Connect a 3-wire power cable to the terminal strip while
paying attention to the correct earth, neutral and line
contacts (115/230 VAC).

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.

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.

Calibration Screwdriver (20 pcs)

CALIBRATION

Make sure the meter is in the measurement mode (the
“MEAS” LED lights on).
Immerse the probe in HI 7033 (84 µS/cm) calibration
solution.
Shake briefly and wait for reading to stabilize.
Using a small screwdriver adjust the calibration trimmer
until the meter displays “42” ppm.

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.

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.

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 tempera-
ture compensation.

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