10.1 mV Measurement
In the mV mode, you will be able to make measurements in either
absolute or relative millivolts, access the mV Setup screens and print
your results to a printer or a computer.
Connect the electrodes you will be using to the meter. See page 3 for
details.
Absolute mV measurements
1. Access the mV measure screen from the main screen
2. Touch
ABS to access the Absolute mV screen.
3. Immerse your rinsed electrode (s) in the sample and stir gently.
4. Record the measurement when STABLE is displayed.
5. Touch
print to store a measurement with an assigned ID# in the
data storage center of the meter or print the data to a printer or
computer.
Relative mV measurements
In this mode, the first mV reading is set to zero and all subsequent
readings are relative to this initial mV measurement.
1. Access the mV Measure screen from the main screen.
2. Touch REL to access the Relative mV screen.
3. Immerse your rinsed electrode(s) in the stirring sample.
4. Record the measurement when STABLE is displayed.
5. Touch print to store a measurement with an assigned ID# in the
data storage center of the meter or print the data to a printer or
computer.
Rinse the electrode with water and blot dry. Do not wipe the electrode.
Wiping the electrode can cause a static charge on the glass bulb that
will result in inaccurate readings.
