GENERAL DESCRIPTION

HI 983317-0, HI 983317-1 and HI 98331700 are conductivity indicators and controllers with a relay output designed for simplicity of use in a wide range of applications.

HI 98331700 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 dosing mode.

OPERATIONAL GUIDE

POWER CONNECTION

HI 983317-0 and HI 98331700

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

HI 983317-1

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:

• 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 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 conductivity value of the solution in

mS/cm unit. Any initial variation on readings may be due to temperature compensation.

The “ALARM” LED will light up when the alarm contact is closed, to indicate an EC value lower 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.

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 electrostatic discharges. Avoid touching this metal band at all times. During operation, 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 minimize any EMC interferences.

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

ovens
