ARM:COUNt?

ARM:COUNt? [<MIN | MAX>] returns the current number of scanning cycles

set by ARM:COUNt. The current number of scan cycles is returned when

MIN or MAX is not specified. With MIN or MAX as a parameter, MIN returns

"1" and MAX returns "32,767".

Parameters

Comments Related Commands: INITiate[:IMMediate]

Example Querying Number of Scans

This example sets a switchbox for 10 scanning cycles and queries the

number of scan cycles set. The ARM:COUN? command returns 10.
