OPERATION
yConnect the supplied 12VDC power adapter to the
meter and to the mains line.
yConnect the pH-electrode to the BNC socket on the
bottom of the meter.
yAlways remove the electrode protective cap before
taking any measurement. If the electrode has been
left dry, soak the tip (bottom 2.5 cm) in M10000B
rinse solution for a few minutes to reactivate it.
yMake sure that the meter has been calibrated
before taking any measurements (see Calibration
Procedure).
yImmerse the tip (2.5 cm) of the pH-electrode into
the sample.
yTurn the instrument on by pressing the ON/OFF key.
yAllow the reading to stabilize and the meter will
start continuous monitoring.
yA blinking alarm will indicate when the measured
pH value is higher or lower than selected setpoint,
depending on user selection.
Note: The output power contact (MC122 only) has no
protection fuse inside the meter. It is recommended to
protected it outside, against failure.
SETPOINT
yThe setpoint can be selected by adjusting the
central front knob to the desired value.
yThe selectable range is from 3.5 to 7.5 pH for MC110;
from 5.5 to 9.5 pH for MC120 and MC122.
yThe nature of the setpoint can be selected by
setting the switch to the desired position (ABOVE
or BELOW).
CALIBRATION PROCEDURE
yRemove the protective cap from the electrode.
yImmerse the electrode tip into a new sachet of
pH 7calibration solution and allow the reading to
stabilize.
yAdjust the pH7 calibration trimmer (on the front) to
display “7.0 pH”.
yOpen a new sachet of pH 4 calibration solution and
use a small quantity to rinse the electrode.
yImmerse the electrode tip into the pH 4 sachet and
allow the reading to stabilize.
yAdjust the pH4/10 calibration trimmer (on the front)
to display “4.0 pH”.
yThe calibration is now complete and the meter is
ready to take measurements.
yIt is suggested to recalibrate the meter at least once
a month, after a prolonged stocking time and after
pH-electrode replacement.
