Channel
List
One or more channels (for the multiplexer, DIO
or TOT channels), the rules are as follows:
(@101): channel 01 on the module in Slot1;
(@101:103): channel 01 through 03
on the
module in Slot1;
(@101:103,301): channel 01 through 03 on the
module in Slot1 and channel 01 on the module
in Slot3.
None
Explanation  You can specify any of the four alarm channels as the alarm channel of the multiplexer,
DIO and TOT channels. For example, you can specify alarm1 as the alarm channel for
103, 205 and 310 channels; alarm1 will generated an alarm when any reading of these
channels meets the specified alarm condition. You cannot specify multiple alarm
channels for a channel.
 A Factory Reset (the
*RST command) specifies ALARm1 to report the alarm situations
of all the multiplexer, DIO and TOT channels.
 A Factory Reset (the
*RST command) clears all the alarm limits and turns off the
alarms. An Instrument Preset (the
SYSTem:PRESet command) or Card Reset (the
SYSTem:CPON command) does not clear the alarm limits and does not turn off the
alarms.
