Description
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
3 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.
Selects whether the delay between channels in the scan list will be automatically or manually selected. By
selecting
Auto , instrument will automatically determine the channel delay based on measurement function,
range, integration time, and AC filter setting. By selecting
inserted between the relay closure and the actual measurement on each channel, in addition to any delay
that will implicitly occur due to relay settling time.
Time , the specified delay (time in seconds) is
