b . If you are in AUTO-READ mode then press to start the measurement .
Once the reading is stable the meter will automatically Log & Print the
results and freeze the display . If the stirrer is enabled then the stirrer will
turn on when
is pressed and turn off once the reading has stabilized .
c . If you are in timed measurement mode then the meter will start making

3 . Remove the electrode from the sample and rinse with deionized water, then
place it in your next sample and repeat step 2 .
4 . Once you have finished measuring samples, rinse the electrode with deionized
water and blot dry . Then consult your electrode manual for proper electrode
storage instructions .
Relative mV & ORP (E
H
) Measurement
After calibrating the electrode the meter is ready to start making measurements .
Make sure that the instrument is in measurement mode (the is lit) and that the
Rel mV is lit . If the is not lit press to return to measurement mode . If the
Rel mV
is not lit, press the until the arrow on the left of the display is pointing
at the top line . Then press / until the
Rel mV
lights . You are now ready to
