OPERATION
y
Connect the supplied 12 VDC power adapter to
the meter and to the mains.
y
Make sure the meter has been calibrated before
taking any measurements (see Calibration
Procedure).
y
Immerse the tip (4cm) of the Conductivity
probe into the sample.
y
Turn the instrument on by pressing the ON/OFF
key.
y
Wait for thermal equilibrium to be reached and
the meter will start continuous monitoring.
y
Set the BELLOW / ABOVE alarm activation
switch in the desired position.
y
A blinking alarm will indicate when the
measured EC or TDS value is lower/higher
than the setpoint (in accordance the BELLOW
/ ABOVE switch).
SETPOINT
y
The setpoint can be selected by adjusting the
central front knob to the desired value.
y
The selectable range for MC310 is from 1.0 to
5.0 mS/cm.
The selectable range for MC410 is from 700 to
1900 ppm.
CALIBRATION PROCEDURE
y
Clean the probe with alcohol and let it dry (if a
more thorough cleaning is required, brush the
metal pins with fine sandpaper and then rinse
with water).
y
Open a sachet of suitable conductivity
calibration solution and immerse the probe,
making sure that metal pins are completely
submerged.
Use M10031 (1413
µ
S/cm
) for MC310 and M10442
(1500 ppm) for MC410.
y
Turn the meter on by pressing the ON/OFF key.
y
Wait until the reading stabilize for temperature
variations, and then adjust the EC/TDS
calibration trimmer on the front panel with the
supplied screwdriver until the display shows:
“1413” µS/cm for MC310 and “1500” ppm for
MC410.
The calibration is now complete and the meter is
ready for use.
The instrument should be re-calibrated at least
once a month, or when the probe is changed.
