Measured Value Differential
You also have the option of
measuring and displaying a value
differential between channel A
and B.
The channel A–B differential
value can only be measured if
two sensors with identical
measurement ranges are
connected. The differential value
always appears in the second line
of the display and is indicated by
A–B.
Note that the differential is always
A–B, consequently it might be
necessary to transpose the
connection of the sensors to
channel A and B.
To calculate the differential, press
the left or right arrow key next to
Mode. If pressed again, the
differential display switches off.
Having the differential displayed
can be done for the current
measured values and for the
minimum and maximum values.
