[ROUTe:]SCAN:MODE
[ROUTe:]SCAN:MODE <mode> sets the Form C switch channels defined
by the [ROUTe:]SCAN <channel_list> command for "no measurements".
The SWITCH device driver for the E1442A also supports Form C
switches which use this command to close appropriate tree relays for a
specific kind of measurement (such as 2-wire and 4-wire ohms that
require different tree relay closures).
For compatibility in use with the switchbox device driver, the E1 442A
accepts the SCAN:MODE command but the command has no effect on
Form C operation. It is important to note that the command erases the
current SCAN list when executed.
NOTE This command erases the current SCAN channel list. SCAN:MODE must
be followed by a [ROUTe:]SCAN command to re-establish a scan channel
list.
Parameters
Comments Order of Command Execution: If used, [ROUTe:]SCAN:MODE must be
executed before [ROUTe:]SCAN <channel_list> because SCAN:MODE
erases the current SCAN list. The SCAN:MODE command is not needed
for Form C Switch operation.
