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. 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
Remove the instrument from the packing material and
examine it carefully to make sure that no damage has
occurred during shipment. If noticeable damage is found,
notify your Dealer.
Each meter is supplied complete with:
ySE-600 preamplified non refillable double junction
combination pH electrode with built in EC/TDS probe and
temperature sensor; 1m (3.3’) cable.
ypH7.01, 1413 µS/cm & 1382 ppm (for MW801) or 1500ppm
(for MW802) solutions, 20 mL each.
yInstruction Manual.
y1 x 9V battery.
OPERATION
Slide the battery compartment cover located on the back
of the meter o, 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 a pH7
(M10007) buer solution for a few minutes to reactivate it.
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.
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.
pH Calibration
A. PREPARATION
Single point manual calibration. Choose buer.
If you are going to measure samples near pH 7 use 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.
Measure the temperature of the buer solution with a
thermometer.
Adjust the calibration knob until the LCD shows the pH value
of the buer at the measured temperature (see pH versus
temperature chart).
pH Calibration
The calibration is now complete and the meter is ready for
use.
EC/TDS Calibration
A. PREPARATION
Single point EC calibration.
Choose appropriate standard:
Model MW801: use 1382 ppm (M10032B) for TDS or
1.413µS/cm (M10031B) for EC calibration.
Model MW802: use 1500 ppm (M10442B) for TDS or
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.
EC/TDS Calibration
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 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 9V 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 9V 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.
