GENERAL OPERATIONS 
. GENERAL OPERATIONS
.. POWERING THE METER ON & OFF
Press the ON/OFF key to power the meter on or o.
At power-on the instrument performs an auto-diagnostic test. All
LCDsegments are displayed for a few seconds.
.. BATTERY MANAGEMENT
The meter is supplied with 3 x .V Alkaline AA batteries. To conserve
battery, the meter will turn o automatically after 10 minutes of
inactivity (see Auto O, GENERAL SETUP OPTIONS section).
From measurement screen, use  keys to check the battery
percentage.
Battery replacement
1. Turn the meter o.
2. Remove the 4 screws on the back of the meter to open the
battery compartment.
3. Remove the old batteries.
4. Insert the 3 new 1.5V AA batteries while paying attention to
their polarity.
5. Close the battery compartment using the 4 screws.
.. CONNECTING THE PROBE
MA852 is connected to the meter through a DIN connector, making
attaching and removing the probe an easy process.
yWith the meter o, connect the probe to the DIN socket on the
top of the meter.
yAlign the pins and key then push the plug into the socket.
yRemove the protective cap from the probe before taking
measurements.

 MW Portable Meter
.. ELECTRODE CARE & MAINTENANCE
Calibrating & Conditioning
Maintaining a combination pH/EC/TDS/Temperature electrode is
critical to ensure reliable measurements.
Frequent 2- or 3-point calibrations are recommended to ensure
accurate and repeatable results.
Prior to first use
1. Remove the protective cap. Do not be alarmed if salt deposits
are present, this is normal. Rinse the electrode with distilled
or deionized water.
2. Place the electrode in a beaker containing MA9016 Cleaning
solution for a minimum of 30minutes.
Note: Do not condition a pH electrode in distilled or deionized
water as this will damage the glass membrane.
3. After conditioning, rinse the sensor with distilled or deionized
water.
Note: To ensure quick response and avoid cross-contamination,
rinse the pH electrode tip with the solution to be tested before
measurement.
Best practice when handling an electrode
ypH electrodes should always be rinsed between samples
with distilled or deionized water.
yBlot the end of the pH portion of this probe with lint-free paper.
Do not wipe to avoid erroneous readings due to static charges.
yConnectors should be clean and dry.
Storage
To minimize clogging and ensure quick response time, the glass
bulb and the junction should be kept hydrated.
Add a few drops of MA9015Storage solution to the protective cap.
Replace the storage cap when the probe is not in use.
Note: Never store the probe in distilled or deionized water.

GENERAL OPERATIONS 
Regular Maintenance
yInspect the probe. If cracked, replace the probe.
yInspect the cable. Cable and insulation must be intact.
yConnectors should be clean and dry.
yRinse o salt deposits with water.
yFollow storage recommendations.
If electrodes are not maintained correctly, both accuracy and
precision are aected. This can be observed as a steady decrease
in the slope of the electrode.
The slope (%) indicates the sensitivity of the glass membrane,
the oset value (mV) indicates the age of electrode and provides
an estimation when the probe needs to be changed. The slope
percentage is referenced to the ideal slope value at 25°C.
Milwaukee Instruments recommends that the oset does not
exceed ± 30mV and that the slope percentage is between 85-105%.
When the slope value drops below 50 mV per decade (85 %
slope eiciency) or the oset at the zero point exceeds ± 30mV,
reconditioning may improve performance, but a change of
electrode may be necessary to ensure accurate pH measurements.
Electrode Status
MW805 displays electrode status after calibration. See probe icon
on the LCD screen. The assessment remains active for 12 hours
and is based on the electrode oset and slope during calibration.
5 bars Excellent condition
4 bars Very good condition
3 bars Good condition
2 bars Fair condition
1 bar Poor condition
1 bar blinking Very poor condition
no bar Not calibrated
Recommendations:
y1 bar: Clean the electrode and recalibrate. If there is still only
1bar or 1bar blinking after recalibration, replace the probe.
yNo bar: Instrument was not calibrated on current day or a
one-point calibration was performed with previous calibration
not yet deleted.
