Triggering Measurements
Before the multimeter will take readings, three separate events must occur in the
proper order. These events are (1) the trigger arm event, (2) the trigger event, and
(3) the sample event. Sub-sampling (discussed in
arming (discussed in this chapter) are the only exceptions to this triggering
hierarchy. As shown in
order listed, the multimeter begins to make the specified reading(s). In the
power-on state, the multimeter is configured so that it makes readings
automatically; that is, all three events are set to AUTO. For most applications, you
will need to use only one or two of these events and leave the other event(s) set to
AUTO. This section describes the various events that can be used to satisfy the
trigger arm, trigger, and sample event requirements and contains examples
showing how to use these events.
The examples in this manual are intended for Hewlett-Packard Series 200/300

computers using BASIC language. They assume a GPIB interface select code of 7
and a device address of 22 resulting in a combined GPIB address of 722. Some
of the examples in this section store readings in memory while others transfer
readings to the controller. Reading destination is discussed in detail later in this
