TrigHold operation

AutoHold operation
Pressing the for more that 1 second activates the
AutoHold if the multimeter is not in the MaxMin, Peak, or
Data Logging recording modes.
AutoHold operation monitors the input signal and updates
the display and, if enabled, emits a beep, whenever a new
stable measurement is detected. A stable measurement is
one that does not vary more than a selected adjustable
(AutoHold threshold) variation count for at least one second
(default 500 counts). Open lead conditions are not included
in the update.
To change the default AutoHold threshold count see
“Changing the variation count” on page 113 for more
information.
