IMER
The Timer function is used for programming the automatic measurement start (and turning the
instrument on if it was turned off) at a given time and day of a week.
Note: In the Simple interface mode, the Timer position is hidden, but the instrument will use
settings previously defined in the Advanced mode or default settings (Timer: Off)
.
The Timer position allows you to programme the internal
real-time clock to act as a delayed start timer. The
instrument will be switched on automatically at the
programmed time and will perform the measurement with
the same settings used before the instrument was
turned off with one exception (see below Note).
<ENT>
Note: When Timer is On, measurements will be performed from defined Start to Stop times
because the Repetition Cycles parameter will be changed to Inf (path: <Menu> /
Measurement / General Set.). The last integration may be cut.
