You cannot “worsen” the resolution to less than one significant digit.
Deviation Measurement
In deviation measurement the read-
ing of the main port is compared to
a reference value. The reference
value is subtracted from the read-
ing of the main port. Start the de-
viation measurement by selecting:
D/Menu
and B/Window 2 Setup, if
needed,
or ,
1/Special Measurements,
Deviation Meas….
You can enter the reference value
when you start the special mea-
surement mode.
Note.
Keep in mind that when the displayed deviation reading is small
compared to the actual reading, a significant part of the deviation
value may be measurement error. See the specifications for mea-
surement errors at the actual measurement level.
