OPERATIONAL GUIDE
yRemove the electrode and turn 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 stable
reading, i.e. the instability indicator
(hourglass) on the LCD turns o.
yThe ORP (mV) value will be displayed on
the main LCD, while the temperature is
shown 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 normal

°F); then press again ON/OFF to return to
the normal mode.
ELECTRODE REPLACEMENT
yRemove the protective cap and unscrew

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 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
