Channel Delay<br />
You can control the pacing of a scan sweep by inserting a delay between<br />
multiplexer channels in the scan list (useful for high- impedance or<br />
high- capacitance circuits). The delay is inserted between the relay closure<br />
and the actual measurement on the channel, in addition to any delay that<br />
will implicitly occur due to relay settling time. The programmed channel<br />
delay overrides the default channel delay that the instrument automatically<br />
adds to each channel.<br />

You can set the channel delay to any value between 0 seconds and<br />
60 seconds, with 1 ms resolution. You can select a different delay for<br />
each channel. The default channel delay is automatic; the instrument<br />
determines the delay based on function, range, integration time, <br />
and ac filter setting (see “Automatic Channel Delays” on page 121).<br />
You can select a unique delay for every channel on the module.<br />
The channel delay is valid only while scanning. If no channels have<br />
been assigned to the scan list, the specified channel delay is ignored<br />
(no error is generated).<br />
