Agilent Technologies 34420A User Manual

To Select a Range
You can let the meter automatically select the range using autoranging
or you can select a fixed range using manual ranging.
• Autoranging is selected at power-on and after a remote interface reset.
• Autorange thresholds:
Down range at <10% of range
Up range at >120% of range
• If the input signal is greater than the present range can measure, the
meter will give an overload indication ("OVLD").
• When making difference or ratio measurements, an overload on either
channel will give an overload indication ("OVLD").
For voltage measurements, ranging is local to the selected channel. This
means that you can select the ranging method (auto or manual) for each
channel independently. When manually ranging, the selected range is
local to the active channel; the meter remembers the range when you
switch between channels.
