6. mV measurement
The pH 10 series meter allows you to read the absolute mV output of your pH,
ORP or Ion Selective Electrode (ISE). For ORP or ISE electrodes contact your
OAKTON distributor.
1. Connect your ORP or Ion Selective Electrode as shown in section 3
2
Rinse the electrode with deionized or distilled water. This will remove
impurities that have adhered to the electrode body. If the electrode has
dehydrated, soak it for 30 minutes in a 2M–4M KCl solution.
3. Turn the meter on. Make sure the meter is in the Measurement Mode
(MEAS indicator shows on the top center of the LCD). If the meter is not in
the measurement mode, press the CAL/MEAS key until the MEAS indicator
shows on the top center of the display.
4. Press the MODE key until the mV
indicator appears in the lower right
corner of the display.
5. Dip the electrode into the sample.
The glass bulb of the electrode must be
completely immersed into the sample.
Stir the electrode gently to create a
homogeneous sample.
6. When the reading stabilizes, the READY indicator will display.
See Figure O.
NOTE: The pH 10 series meter does not have a relative mV mode. We have
other meters that can take relative mV readings—contact your
OAKTON distributor for information.
7. HOLD feature
This feature lets you freeze the value of
the pH or mV reading for a delayed
observation. HOLD can be used any
time when in MEAS mode.
1. To hold a measurement, press the
HOLD key while in measurement
mode. "HOLD" will appear on the
display. See Figure P.
2. To release the held value, press
HOLD again. Continue to take
measurements.
NOTE: This meter will hold a reading for
up to 20 minutes, because it
features automatic shutoff after
20 minutes to conserve batteries.
