ENTER
with RCD
During programming this key is
used both to enter the desired
program and to confirm the value
of the parameter considered.
When pressed repeatedly, the
key, sub-function RCD, 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 about 4
hours. At the end, the RCD func-
tion is automatically interrupted
and the max. min. and mean
values calculated 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.
