Channel Delay

You can control the pace of a scan sweep by inserting a delay between multiplexer channels in the scan list (useful for high-impedance or high-capacitance circuits). The delay is inserted between the relay closure and the actual measurement on the channel. The programmed channel delay overrides the default channel delay that the instrument automatically adds to each channel.

Channel Delay

∙You can set the channel delay to any value between 0 seconds and

60 seconds, with 1 ms resolution. You can select a different delay for each channel. The default channel delay is automatic; the instrument determines the delay based on function, range, integration time, and ac filter setting (see “Automatic Channel Delays” on the next page).

∙The MEASure? and CONFigure commands set the channel delay

to automatic. A Factory Reset (*RST command) also sets the channel delay to automatic.
