manually adjusted range, automatic range adjustment is more convenient but can
lead to slower measurement. Auto range adjustment can turn the range up to 120%
of the current range and down to less than 10% of the current range. Press

Step 5: Press
AC Filter
and select Filter for measurement. The instrument uses three
different AC filters, allowing you to optimize low-frequency accuracy or shorten AC
stabilization time after changing the amplitude of the input signal.
The three filters are 3 Hz, 20 Hz, and 200 Hz, and in general, you should choose the
highest frequency filter whose frequency is less than the frequency of the signal you
are measuring, because a higher frequency filter results in a faster measurement. For
example, it’s better to use a 20 Hz filter when measuring a signal in the 20 to 200 Hz
range.
If measurement speed is not an issue, choosing a lower frequency filter will result in a
quieter measurement, depending on the signal you are measuring.
Note: To accurately display statistics for AC measurements in front panel
mode, you must use the default manual trigger Delay ([Acquire] >Delay
Man).
