GENERAL DESCRIPTION

HI 981411-0 and HI 981411-1 are pH indicators and controllers with a relay output designed for simplicity of use in a wide range of applications.

The models are panel-mounted with membrane keypads on the front panel and an easy-to-read LCD display.

Power supply, wiring and selection are made via the plugin terminal blocks on the rear panel. The instruments are equipped with a BNC socket and accept input from conventional combination pH electrode.

LED indicators on the front panel identify whether the controller is in set or reading mode, and if dosing device is activated.

Recommendations for Users Before using this product, make sure that it is entirely suitable for the environment in which it is used. Operation of this instrument in residential areas could cause unacceptable interferences to radio and TV equipment. The glass bulb at the end of the electrode is sensitive to electrostatic discharges. Avoid touching this glass bulb at all times. During operation, ESD wrist straps should be worn to avoid possible damage to the electrode 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 this instrument 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.

POWER CONNECTION HI 981411-0

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

HI 981411-1

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.

DOSING CONTACT

This contact (maximum 5A, 240VAC, 30VDC) is used for connection to an alarm or dosing system. The relay contact acts as a power switch for the controlling device.

OPERATING THE METER

All settings of the parameters 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 that the Setpoint is properly adjusted before proceeding.

Attach the pH-electrode to the meter with a BNC connector. Install the electrode in the fittings or immerse it in the solution to be monitored. Press the "MEAS" key.

The LCD will show the pH value. Any initial variation on readings may be due to temperature compensation.

The “DOSING” LED will light up when the dosing contact is closed.

CALIBRATION

Make sure the meter is in the measurement mode (the “MEAS” LED lights on). Immerse the electrode in HI 7007 (pH7.01) buffer solution (or any buffer solution close to the operating pH value). Shake briefly and wait for reading to stabilize. Adjust the calibration trimmer until “7.0” is displayed on the LCD.

SETPOINT

Press the "SET" key. The display will show the default or previously adjusted value. Using a small screwdriver adjust
