Note:
The integration time can be set for any measurement function except frequency, period,
continuity (FAST) and diode test (MEDium). For frequency and period, this value is gate
time of 1sec.

Trigger Operations
The multimeter's triggering system allows you to generate triggers either manually or automatically or
externally and take multiple readings per trigger. The following paragraphs discuss front panel triggering,
the programmable trigger delay and the reading hold feature.
4.2.1
Trigger model
The flowchart of Figure 4-2 summarizes triggering process of the instrument. It is called a trigger model
because it is modeled after the SCPI commands used to control triggering.
Idle
The instrument is considered to be in the idle state whenever it is not performing any measurement. Once
Model DMM is taken out of idle, operation proceeds through the flowchart.
Wait for Trigger
The control source holds up operation until the programmable event occurs and is detected. See
description below for trigger sources:
Immediate
With this trigger source, event detection is immediately satisfied allowing operation to continue.
