4 Making Measurements
Figure 4-2 Multiple trigger arming
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
