Softkey Description
AC Filter Specifies which AC filter to use. The instrument uses three different AC filters that enable you either to optimize low
frequency accuracy or achieve faster AC settling following a change in input signal amplitude. The three filters are
Hz , 20 Hz , and 200 Hz , and you should generally select the highest frequency filter whose frequency is less than
that of the signal you are measuring, because higher frequency filters result in faster measurements. For example,
when you are measuring a signal between 20 and 200 Hz, you should use the 20 Hz filter. If measurement speed is
not an issue, choosing a lower frequency filter may result in quieter measurements, depending on the signal that
you are measuring.
Delay Selects whether the delay between channels in the scan list will be automatically or manually selected. By selecting
Auto/ Time Auto , instrument will automatically determine the channel delay based on measurement function, range, integration
time, and AC filter setting. By selecting
ure and the actual measurement on each channel, in addition to any delay that will implicitly occur due to relay set-
tling time.
