Instrument Errors

261

Not able to execute while scan initiated

 

While a scan is running, you cannot change any parameters that affect

 

the scan (channel configuration, scan interval, scaling values, alarm

 

limits, issue a Card Reset, or recall a stored state). To stop a scan in

 

progress, send the ABORt command or a bus Device Clear.

271

Not able to accept unit names longer than 3 characters

 

For Mx+B scaling, you can specify a custom label with up to three

 

characters. You can use letters (A-Z), numbers (0-9), an underscore ( _ ),

 

or the “#” character which displays a degree symbol ( ° ) on the front panel.

272

Not able to accept character in unit name

 

For Mx+B scaling, you can specify a custom label with up to three

 

characters. The first character must be a letter or the “#” character (the “#”

 

character is allowed only as the leftmost character in the label).

 

The remaining two characters can be letters, numbers, or an underscore.

281

Not able to perform on more than one channel

 

You can perform this operation on only one channel at a time. Check the

 

channel list that you sent with this command to see if it contains more

 

than one channel. This error is generated by the ROUTe:MON and

 

DATA:LAST? commands.

291

Not able to recall state: it is empty

 

You can only recall a state from a location that contains a previously

 

stored state. The state location that you attempted to recall is empty.

 

The storage locations are numbered 0 through 5.

292

Not able to recall state: DMM enable changed

 

 

The enable/disable state of the internal DMM has been changed since

6

 

the instrument state was stored. Use the INSTrument:DMM? command

 

to determine the state of the internal DMM. For more information,

 

 

see “Internal DMM Disable” on page 145.

 

301

Module currently committed to scan

 

 

When you add a multiplexer channel to a scan list, that entire module

 

 

is dedicated to the scan. You cannot perform low-level close or open

 

 

operations on any channels on that module (even those channels that

 

are not configured). To stop a scan in progress, send the ABORt command or a bus Device Clear.
