Check
whether
Sensor A
is selected in the drop-down
list for the primary channel and
Sensor B
in the drop-

The ratio of two powers is dimensionless – this is why
only
dB
,
∆
%
and
1
are available in the unit list. The symbol
∆
%
represents the relative uncertainty in % (0 % means
the powers in both channels are equal), the symbol
1
represents a straight ratio, i.e. not the log of a ratio.
