manual ranging. Manual ranging (or up-only autoranging)
is essential for low frequency measurements.
For measuring signals that are biased on a dc level (such
as an amplifier operating on a single supply or the output
of a dc PSU), ac coupling can be used. AC+DC coupling is
the normal option and should be used where possible.
A scaling factor can be entered for each channel for use
with attenuators such as x10 oscilloscope probes. A
nominal value can be entered or the attenuation factor of
the probe can be measured and the precise value entered.
The measured voltage will be displayed after multiplication
by the scale factor.
If the channel has been set for use with an external shunt
then the value of the shunt can be entered.
