This terminal allows you to input a trigger signal to execute a measurement command. The
rising edge (or falling edge) from the LOW state (or HIGH state) in the TTL compatible
signal is detected as a trigger by this external trigger input terminal. To trigger
measurements by inputting signals into this terminal, it is necessary to set a trigger source
in the EXTERNAL (external trigger input terminal) in advance. For details on the input
signal conditions of this terminal, please refer to Chapter 12, "Specifications and
Supplemental Performance Characteristics," on page 251.
