The measure screen provides readout of
the current sample measurement. You
can use this meter when the Auto Read
function is active or when it is inactive.
When the auto read function is active,
the meter will lock onto a reading when
the meter recognizes it as stable. The
meter will not deviate from this reading
until the Measure button is touched.
If the Auto Read mode is inactive, then
the meter will continuously monitor the
pH of the sample and the measure
display screen will indicate any
fluctuation in the sample pH. Regardless
of the status of the Auto Read mode,
STABLE will flash as the meter
recognizes the measurement as stable.
Once the meter is standardized, you are
ready to take pH measurements of your
sample.
To Measure pH of a Sample with Auto Read ON
1. Immerse the rinsed electrode(s) in the sample and stir gently.
2. Touch Measure to begin measuring your sample. The meter will accept the reading and
display STABLE* when the measurement meets the selected stability criteria.
OR
To Measure pH of a Sample with Auto Read OFF
1. Immerse the rinsed electrode(s) in the sample and stir gently.
