Comments

• For the scanning multimeter, CONFigure sets one scan (pass)

through the channel list. The

TRIGger:COUNt command can specify

up to 16,777,215 scans.

• The multimeter makes one measurement per channel per scan.

However, multiple measurements per channel (per scan) can be

made when scanning a single channel. The number of measurements

taken during a single channel scan is set with the

SAMPle:COUNt

command.

• The multimeter output buffer can hold eight readings. When the

buffer fills, measurements are suspended until readings are read from

the buffer (by the computer) to make space available.
