Aspects associated with this function include:

Opening the channels and analog backplane relays for a measuring function.

The configuration (see
channel dictates whether a paired channel is open or not. For channel patterns, the
channels associated with it will be opened. Channel patterns don't support the
concept of pairing channels for multi-wire measurements.

The configuration (see
backplane relay 1 and 2 are opened.

Does not use analog backplane relays specified by
9-42) function or poles setting set by
An error will be generated if:

There is a syntax error in parameter string.

There is an empty parameter string.

The specified channel or channel pattern is invalid.

A channel number does not exist for installed card in slot specified.

A slot is empty.

The channel pattern does not exist.

Does not support being closed like a digital I/O channel.

Channel is paired with another bank for a multi-wire application.

Channel's configuration is ―nofunction‖.
Once an error is detected, the command stops processing. Channels will open only if no
error is detected. Otherwise, channels remain unchanged.
This command allows a user to separate the opening of channels with closing in a
measuring aspect. Therefore, you may execute any number of commands between the
open and close commands to satisfy your application needs.

To open Channel 3 on Slot 3 and a channel pattern called "mychans":
dmm.open("3003, mychans")
To open all channels:
dmm.open("allslots")
To open all channels on Slot 1 and Slot 2:
dmm.open("slot1, slot2")
