External Scale
Both optical and electrical channels have an External scale setting which
allows the user to enter in an offset value to compensate for gains or losses not
associated with the device under test. This feature is useful for adjusting out
the effects of devices such as test fixtures and attenuators so that the reading
on the display gives the measurement value associated with only the actual
device under test.
