OPERATION
yThe meter is supplied complete with a 9V battery.
Slide o the battery compartment cover on the back
of the meter. Install the battery into the battery clip
connector while observing polarity.
yAlways remove the electrode protective cap before
taking any measurement. If the electrode has been
left dry, soak the tip (bottom 2.5 cm) in rinse solution
(M10000B) for a few minutes to reactivate it.
yConnect the pH electrode to the BNC socket on the
top of the meter.
yMake sure that the meter has been calibrated
before taking any measurements (see Calibration
Procedure).
yImmerse the tip (2.5 cm) of the pH electrode into the
sample.
yTurn the instrument on by pressing the ON/OFF key.
yAllow the reading to stabilize before taking
measurements.
yAfter measurements, switch the meter o and store
the electrode with a few drops of storage solution
(SE-220) in the protective cap.
CALIBRATION PROCEDURE
yRemove the protective cap from the electrode.
yRinse tip o with distilled water or a small quantity
of pH 7.
yImmerse the electrode tip into a new sachet of pH7
calibration solution and allow the reading to stabilize.
yAdjust the pH7 (OFFSET) calibration trimmer to display
“7.0pH”.
yOpen a new sachet of pH4 calibration solution and
use a small quantity to rinse the electrode.
yImmerse the electrode tip inside the pH4 sachet and
allow the reading to stabilize.
yAdjust the pH4/pH10 (SLOPE) calibration trimmer to
read “4.0 pH”.
yThe calibration is now complete and the meter is
ready to take measurements.
yIt is suggested the meter be calibrated at least once a
month, after a prolonged period of inactivity, and after
electrode replacement.
BATTERY REPLACEMENT
When the battery becomes weak the meter will
display “ “.
When the low battery indicator appears, the battery has
only about 50 hours of working time left. A low battery will
result in unreliable measurements.
Prompt battery replacement is required. Battery
replacement must only take place in a non-hazardous
area using an alkaline 9V battery.
Turn the meter o, slide the battery compartment
cover located at the rear of the meter o and replace
the 9V battery with a new one. Make sure the battery
contacts are fully engaged in the connector, seat the
battery in its compartment and replace the cover.
