Programming the Trigger System

The Meter is designed to provide extensive control over the triggering of a single
measurement or series of measurements. One trigger can cause the Meter to take a single
measurement or multiple measurements up to 50,000 per trigger.
Operating the Meter remotely requires selecting one of three trigger methods: internal,
external, or bus triggering. Once a source is selected, the Meter must be in a "wait-for-
trigger" state before the trigger will start a measurement cycle.
Figure 4 shows the multimeter's triggering system.
