FUNCTION
DESCRIPTION
with RCD
When pressed repeatedly, the
s
key (RCD sub-function) starts and
stops the record function, which
calculates and stores the maxi-
mum, minimum and mean values.
When the RCD key is held down
the instrument emits a short beep
followed by a long one. This con-
firms that the max., min. and
mean values stored previously
are being erased from the
memory and a new series of
recordings is started which will be
used as the basis on which to cal-
culate and store new max., min.
and mean values.
After resetting of the max., min.
and mean values, the RCD func-
tion has a duration of about
30,000 readings, that is 4 hours.
At the end, the RCD function is
automatically interrupted and the
max. min. and mean values calcu-
lated up till then are maintained.
During RCD mode the Auto
Power Off function is disabled and
the battery symbol flashes at a
frequency of 2 Hz.
Attention:
If the battery symbol does not fla-
sh at a frequency of 2 Hz when
the RCD key is pressed, it means
that the RCD function has stored
more than 30,000 acquisitions
and cannot continue any further.
