Precision of the Readout Value
The precision of the power or energy readout can simply be changed by clicking
on the power or energy value in the numeric or needle screen. The reading will
toggle between 3, 4 or 5 significant digits.
Units of Measure
The units of measure can be selected by clicking on the measurement unit in the
numeric or needle display. A list box will open and offer sensor depending

is displayed in a subpanel.
Alternative Unit
Depending on the sensor type, alternative measurement units are available and
can be selected in both the numeric and needle view panels by clicking to the
