• Turn the instrument on by pressing the ON/OFF key.
• Wait for thermal equilibrium to be reached and the meter will start continuous monitoring.
• Set the BELLOW / ABOVE alarm activation switch in the desired position. · A blinking alarm will indicate when the measured EC or TDS value is lower/higher than the setpoint (in accordance the BELLOW / ABOVE switch).

NOTE: The output power contact has no protection fuse inside the meter. It is recommended to protected it outside, against failure.

SETPOINT:

• The setpoint can be selected by adjusting the central front knob to the desired value.
• The selectable range for MC311 is from 0.8 to 2.8 mS/cm.

CALIBRATION PROCEDURE:

• Clean the probe with alcohol and let it dry (if more thorough cleaning is required, brush the metal pins with fine sandpaper and then rinse with water).
• Open a sachet of M10039 (5.00 mS/cm) conductivity calibration solution and immerse the probe, making sure that metal pins are completely submerged.
• Turn the meter on by pressing the ON/OFF key.
