OPERATION:

• Connect the supplied 12 VDC

power adapter to the meter and

to the mains line.

• Connect the pH and ORP elec-

trode to the BNC socket of the

meter.

• Always remove the electrode

protective caps before taking any

measurement. If the electrodes

have been left dry, soak the tip

(bottom 2.5 cm) in rinse solution

(M10000B) for a few minutes to reactivate them.

• Make sure that the meter has been calibrated before taking any measurements (see Calibration Procedure).

• Immerse the tip (2.5 cm) of the electrodes into the samples.

• Turn the instrument on by pressing the ON/OFF key.

• Allow the reading to stabilize and the meter will start continuous monitoring.

• A blinking alarm LED will indicate when the measured pH value is higher or lower than the setpoint depending on user selection.

• When the alarm LED is blinking, there is power in the output power socket. NOTE: The output power contact has no protection fuse inside the meter. It is recommended to protected it outside, against failure.
