5.11 PROGRAMMING THE INSTRUMENTS INTERNAL TIMER TIMER
The Timer function is used to programme the automatic start-up of the measurement at a given time and day
and with the parameters set in the Measurement section.
The Timer position allows you to programme
the internal real-time clock to act as a delayed
start and stop 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.

Modes of the timer function
The timer can be switched off (Off), switched
on only once (Single), or switched on many
times regularly (Multiple) with the period
between two consecutive measurements
(Repetition).
In the case the timer is active (Single or Multiple) and the instrument is switched on the clock icon appears
until finishing the programmed measurements.
