Trigger Mode

This multimeter has two types of trigger mode.
• Internal — triggers measurements continuously.
• External — triggers a measurement only when a direction is given.
The external trigger is used with a delay settling that has been set by the
multimeter automatically. The amount of trigger delay varies depending on
different function. When external trigger is enabled, the multimeter
determines the range for the primary display based on the input at that
time.
Autoranging response time is required before a reading is displayed when
you change the input after a trigger is received.
