TRIGger:COUNt {<count> | MIN | MAX | DEF | INFinity}
TRIGger:COUNt? [{MIN | MAX | DEF}]
Specifies the number of triggers that are accepted by the instrument before returning to the "idle" trigger state.
Trigger count is always 1 in DMM digitize mode. Error -221,"Settings conflict; DMM digitizing mode has
been disabled" will be generated when you send the command to set trigger count to a value other than 1.
Parameter Typical return
<count> = 1 to 1,000,000 (1x10
6
), or continuous (INFinity).
Default: 1
+1.00000000E+00
For a continuous trigger (INFinity), the query returns "9.9E37".
Configures two channels for DC voltage measurements, puts the channels in the scan list (the scan list is redefined), and sets the trigger
count to 10. For each trigger received, one reading is returned for each channel (20 readings total).

INIT
– After setting the trigger count, you must place the instrument in the "wait-for-trigger" state using the INITiate or
READ? command. A trigger will not be accepted from the selected trigger source (TRIGger:SOURce command)
until the instrument is in the "wait-for-trigger" state.
– For the BUS source, the trigger count sets the number of *TRG commands that will be accepted before return-
ing to the "idle" trigger state.
– For the EXTernal source, the trigger count sets the number of external pulses that will be accepted before
returning to the "idle" trigger state.
– For the ALARm<n> source, the trigger count sets the number of alarms that will be accepted before returning
to the "idle" trigger state.
– For the TIMer source, the trigger count sets the number of times the instrument will sweep through the scan
list and therefore determines the overall duration of the scan.
– You can store at least 100,000 readings in reading memory and all readings are automatically time stamped. If
memory overflows, the new readings will overwrite the first (oldest) readings stored; the most recent readings are
always preserved.
– To set the trigger-to-trigger interval (in seconds) for measurements on the channels in the present scan list, use
the TRIGger:TIMer command.
– The CONFigure and MEASure? commands automatically set the trigger count to 1.
– The instrument sets the trigger count to 1 after a Factory Reset (*RST command).
