6 Command Reference
Power-on event = AUTO.
Default event = AUTO.
Remarks
– Since the TIMER event designates an interval between readings, it only applies
– You can use the SWEEP command to replace the two commands: NRDGS
– When SYN is used for more than one of the trigger arm, trigger, or sample
– Query command: The NRDGS? query command returns two responses
– Related commands: DELAY, LEVEL, RMEM, SLOPE, TARM, TIMER, TRIG,
Examples
SYN event
In the following program, line 70 requests data from the multimeter. This satisfies
the SYN event and initiates a reading. The reading is then sent to the controller
and printed. The process repeats until the three readings have been taken and
printed.

when count is greater than one. The first reading occurs without the TIMER
interval. However, you can insert a time interval before the first reading with
the DELAY command. (The TIMER event suspends autoranging.)
n,TIMER and TIMER n. The SWEEP command specifies the number of readings
and the interval between readings. These commands are interchangeable; the
multimeter uses whichever command was executed last in the programming.
Executing the SWEEP command automatically sets the sample event to
TIMER. In the power-on, RESET, and PRESET states, the multimeter uses the
NRDGS command.
events, a single occurrence of the SYN event satisfies all of the specified SYN
event requirements. This is shown in the second "SYN event" example below.
separated by a comma. The first response is the specified number of readings
per trigger. The second response is the present sample event. Refer to
commands near the front of this chapter for more information.
