Multiple Trigger
Arming
The second parameter of the TARM command allows you to specify multiple
trigger arming. When multiple trigger arming is specified, a single
occurrence of the trigger arm event arms the multimeter the specified number
of times. (The trigger arm event must be SGL for multiple arming.) This
causes the multimeter to make multiple groups of readings as shown in Figure
17.
In the following program, the NRDGS command selects 10 readings per
trigger event. The second parameter of the TARM command specifies 5
armings. This program stores 5 groups of ten readings for a total of 50
readings.

Making Synchronous
Readings
You can synchronize the multimeter to the controller by setting the trigger
arm, trigger, and/or sample event to synchronous (SYN). The synchronous
event occurs whenever the multimeter's output buffer is empty, reading
memory is off or empty, and the controller requests data. This means that
measurements are made whenever the controller wants them. This is a very
important feature for remote operation, especially when the multimeter is in
the high-speed mode.
In the high-speed mode, the synchronous event ensures that the controller is
ready to accept readings and will not slow the reading rate. Refer to
Figure 17. Multiple trigger arming
