RECOMMENDATION
Before using this product, make sure it is entirely suitable for
your specific application and for the environment in which it is
used. Any modification introduced by the user to the supplied
equipment may compromise the meter’s performance. For
your and the meter’s safety do not use or store the meter
in hazardous environment. To avoid damage or burn, do not
perform any measurement in microwave ovens.
WARRANTY
These instruments are warranted against defects in materials
and manufacturing for a period of 2 years from the date of
purchase. Probe is warranted for 6 months. This warranty
is limited to repair or free of charge replacement if the
instrument cannot be repaired. Damage due to accidents,
misuse, tampering or lack of prescribed maintenance is not
covered by warranty. If service is required, contact your local
Milwaukee Instruments Technical Service. If the repair is not
covered by the warranty, you will be notified of the charges
incurred. When shipping any meter, make sure it is properly
packaged for complete protection.

PRELIMINARY EXAMINATION
Each meter is supplied complete with:
ySE600 preamplified non refillable double junction
combination pH electrode with built in EC/TDS probe and
temperature sensor; 1m (3.3’) cable
yCalibration solutions, 20mL each
▶ pH7.01, 1413 µS/cm, 1382 ppm (MW801)
▶ pH7.01, 1413 µS/cm, 1500 ppm (MW802)
yInstruction manual
y1 x 9 V battery
OPERATION
Slide o the battery compartment cover located on the back
of the meter, and install the battery into the battery clip
connector while observing polarity.
Connect the probe to the meter securely by aligning the pins
with the socket and pushing the plug in.
DIN Connector
Always remove the electrode protective cap before use.
Make sure that the meter has been calibrated before taking
any measurements (see calibration procedure).
Turn the instrument on by pressing the ON/OFF key.
ON/OFF
pH MEASUREMENTS
If the electrode has been left dry, soak the tip in MA9015
Storage Solution for a few hours (or overnight) to reactivate.
Submerge the tip of the electrode into the sample to be
measured, select the pH mode and allow the reading to
stabilize before taking measurements.
EC/TDS MEASUREMENTS
Immerse the tip of the electrode into the sample to be tested.
Select the measurement range (EC or TDS) and wait for the
temperature sensor to reach thermal equilibrium with the
samples before taking measurements.
EC/TDS measurements have a high thermal dependency
and readings taken with this instrument are temperature
compensated.
AFTER MEASUREMENTS the instrument should be switched
o and the probe cleaned and stored with a few drops of
storage solution in the protective cap.
CALIBRATION PROCEDURE
Remove the protective cap from the electrode.
Switch the meter on.
Select the range pressing the appropriate key for pH, EC or TDS.
For best calibration results we suggest calibration to be
done at room temperature (around 25 °C/77 °F).
pH Calibration
A. PREPARATION
Single point manual calibration. Choose buer.
If you are going to measure samples near pH 7use pH 7.01
buer solution (M10007B) for calibration; use pH 4.01 buer
solution (M10004B) for acidic measurements, or pH 10.01
(M10010B) for alkaline measurements.
M10007B
B. PROCEDURE
Rinse the tip of the electrode and immerse it in the
calibration solution. Wait a couple of minutes for the reading
to stabilize.
Adjust the calibration knob until the LCD shows the pH value
at the value printed on the used buer standard.
pH Calibration
Calibration is now complete and the meter is ready for use.
EC/TDS Calibration
A. PREPARATION
Single point EC calibration.
Choose appropriate standard:
yMW801: use 1382 ppm (M10032B) for TDS or
use 1413µS/cm (M10031B) for EC calibration.
yMW802: use 1500 ppm (M10442B) for TDS or
use 1.413mS/cm (M10031B) for EC calibration.
Calibration
Solution
B. PROCEDURE
Immerse the tip of the electrode in the standard solution.
Wait for the reading to stabilize, and thermal equilibrium be
reached.
Turn the EC/TDS calibration knob until the display shows
the EC or TDS reading at 25 °C,value printed on the
calibration bottle’s or sachet’s label you are using.
EC/TDS Calibration
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 or battery is replaced.
Note: The conversion between EC and TDS is made by a
built-in circuit. If calibration is made in EC range, TDS range
is automatically calibrated (or vice versa).
BATTERY REPLACEMENT
The meters are powered by a 9 V battery that is in a
compartment located in the rear of the instrument.
When the battery becomes weak, the instrument
automatically switches o.
Replacement must only take place in a non-hazardous area
using an alkaline 9 V battery.
Slide o the battery compartment cover and replace the old
battery with a new one. Make sure that the battery contacts
are fully engaged in the connector. Seat the battery in is
compartment and replace the cover.
