User Manual

ELECTRODE REPLACEMENT
• Remove the protective cap and unscrew the
plastic ring on the top of the electrode.
• Pull out the MI58P electrode and replace it
with a new one.
• Make 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.
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 off.
It is recommended to replace the batteries im-
mediately.
To replace the batteries unscrew the battery
compartment cap and replace all four 1.5V bat-
teries while paying attention to their polarity.
Make sure the gasket is in place before screw-
ing back the cap.
Batteries should only be replaced in a non-
hazardous area using the battery type specified
in this instruction manual.

Note: When the calibration procedure is com-
pleted, the CAL tag is turned on.
• To 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.
• To 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 cali-
bration and the CAL tag on the LCD turns off.
SETUP
Setup mode allows the selection of temperature
(°C or °F) and pH buffer set for calibration. To
enter the Setup mode, press the ON/OFF but-
ton until “CAL” on the secondary LCD is re-
placed by “TEMP” and the current temperature
unit (e.g. TEMP °C). Then:
• for °C/°F selection: use the SET/HOLD but-
ton; then press the ON/OFF button once to
enter the buffer set selection or twice to return
to the normal measurement mode.
• to change the calibration buffer set: after
setting the temperature unit, press ON/OFF
once and select the buffer set (“pH 7.01
BUFF” or “pH 6.86 BUFF” for NIST) by
