tions. Each Profile can be named and recalled at a moment’s notice. A profile is a sensor setup
complete with measurement units, logging and display preferences, calibration standards, setup of
the Display screen for measurement (i.e. graphing, GLP) and any other sensor configuration. Once
saved, the exact same profile can be used at another time. This is a handy feature if the meter is
used occasionally for additional applications because it saves time in the setup of the meter and
