Milwaukee pH58 User manual

The meter is also provided with BEPS (Battery Error
Prevention System), which avoids any erroneous
readings due to low battery level by automatically
switching the meter o.
It is recommended to replace the batteries
immediately.
To replace the batteries unscrew the battery
compartment cap and replace all four 1.5V batteries
while paying attention to their polarity. Make sure
the gasket is in place before screwing back the cap.
Batteries should only be replaced in a non-
hazardous area using the battery type specified in
this instruction manual.

OPERATIONAL GUIDE
yRemove the electrode cap and immerse the
meter in MA9015 storage solution for 2hours to
activate the electrode.
yTurn the meter on by pressing the ON/OFF button.
All the used segments on the LCD will be visible
for 1 second or as long as the button is pressed.
yImmerse the electrode in the solution to be
tested. Stir gently and wait for the reading to
stabilize, i.e. the instability indicator (hourglass)
on the LCD turns o.
ySelect the pH or ORP (mV) mode by pressing the
SET/HOLD button.
yThe displayed pH value is automatically
compensated for temperature. The ORP (mV)
value will be displayed on the main LCD, while
the temperature will always be displayed on the
secondary LCD.
yTo freeze the display, while in measurement
mode, press and hold the SET/HOLD button.
The “HOLD” message appears on the secondary
display and the reading will be frozen on the
LCD. Press any button to return to the normal
measurement mode.
yTo turn the meter o, press the ON/OFF
button. The “OFF” message will appear on the
secondary display. Release the button.
Note:
yBefore taking any measurement, make sure the
meter is calibrated (the CAL tag is on).
yAfter use always turn the meter OFF, rinse the
electrode with water to minimize contamination
and store it with a few drops of storage (MA9015)
or pH7 (M10007) solution in the protective cap.
NEVER USE DISTILLED OR DEIONIZED WATER FOR
STORAGE PURPOSE.
CALIBRATION PROCEDURE
The ORP (mV) range is factory calibrated. Contact
the nearest Service Center for recalibration, if
necessary.
For better accuracy, frequent calibration of the tester
is recommended. Calibration is also necessary after
electrode replacement, after testing aggressive
chemicals and where extreme accuracy is required.
yTurn the meter on and select the pH mode with
the SET/HOLD button.
yPress and hold the ON/OFF/CAL button until
the “OFF” message on the secondary LCD is
substituted by “CAL”. Release the button.
yThe instrument enters the calibration mode by
displaying “pH 7.01 USE” (or “pH 6.86 USE” if the
NIST buer set was selected).
yFor a single-point calibration, immerse the
electrode in any buer, i.e. pH 4.01, 7.01 (or 6.86),
10.01 (or 9.18).
yThe meter activates the automatic buer
recognition. If no valid buer is detected, the
meter keeps the USE indication active for 12
seconds, and then replaces it with WRNG,
indicating that the sample being measured is
not a valid buer. Otherwise, if a valid buer is
detected, then its value is shown on the primary
display, and REC appears on the secondary LCD.
yIf the pH 7.01 (or pH 6.86) was used, press the
SET button to exit the Calibration mode and the
“OK 1” message will appear on the display. The
first calibration point is stored and the meter
returns to normal measurement mode.
For better accuracy, it is always recommended to
perform a 2-point calibration.
yFor a two-point calibration, immerse the
electrode in pH 7.01 (or pH 6.86) buer solution.
yAfter the first point has been accepted, the
meter will then ask for the second buer and
the message “pH 4.01 USE” will appear.
yRinse the electrode and immerse it in the
second solution (pH 4.01, 10.01 or 9.18).
yIf a valid buer value is detected, the REC
message is displayed and the meter completes
the calibration procedure. The LCD shows the
accepted value with the “OK 2” message and the
instrument returns to the normal measurement
mode. Otherwise, if no valid buer is detected,
the meter displays the WRNG message.
Note: When the calibration procedure is completed,
the CAL tag is turned on.
yTo quit the procedure and return to the last
calibration data, after entering the calibration
mode press the ON/OFF button. The secondary
LCD displays “ESC” for 1 second and then the
meter returns to the normal measurement
mode.
yTo reset to the default values and clear a
previous calibration, press the SET/HOLD button
after entering the calibration mode and before
the first point is accepted. The secondary LCD
displays “CLR” for 1 second, the meter resets to
the default calibration and the CAL tag on the
LCD turns o.
SETUP
Setup mode allows the selection of temperature (°C
or °F) and pH buer set for calibration. To enter the
Setup mode, press the ON/OFF button until “CAL” on
the secondary LCD is replaced by “TEMP” and the
current temperature unit (e.g. TEMP °C). Then:
yfor °C/°F selection: use the SET/HOLD button;
then press the ON/OFF button once to enter
the buer set selection or twice to return to the
normal measurement mode.
yto change the calibration buer set: after
setting the temperature unit, press ON/OFF
once and select the buer set (“pH 7.01 BUFF” or
“pH 6.86 BUFF” for NIST) by using the SET/HOLD
button. Press ON/OFF to return to the normal
measurement mode.
ELECTRODE REPLACEMENT
yRemove the protective cap and unscrew the
plastic ring on the top of the electrode.
yPull out the MI58P electrode and replace it with
a new one.
yMake sure the gaskets are in place before
screwing back the ring.
BATTERY REPLACEMENT
When the batteries become weak, the battery
symbol on the LCD will light up to advise that only a
few hours of working time is remaining.
