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.

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.

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 “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
