Management
of
memorized
data
(only
HD21...4.2)
:
the
message
“
>>>_LOG_DUMP_or_ERAS
”
(Transfer data or erase)
is scrolled in the comment line.
The center figure reports the number of free memory pages (FREE). Pressing
SERIAL/EraseLOG permanently erases all memory data. By pressing LOG/DumpLOG, the
data transfer of the logged data on the serial port is started: the “BAUD-RATE” must have
previously been set to the maximum value (please see the menu items described below and
the paragraph "STORING AND TRANSFERRING DATA TO A PERSONAL
COMPUTER" on page 25).
5)
Print and log interval (only HD21...4.2)
: sets the interval in seconds between two loggings
or data transfers to the serial port. The interval can be set at 0, 1s, 5s, 10s, 15s, 30s, 60s
(1min), 120s (2min), 300s (5min), 600s (10min), 900s (15min), 1200s (20min), 1800s
(30min) and 3600s (1hour).
If the value 0 is set, SERIAL works on command: the
sending of data to the serial port is performed each time the key is pressed
. Recording
(LOG) is performed with one-second intervals even if the interval is set to 0. With an
interval from 1 to 3600s, continuous data transfer is started when the SERIAL key is
pressed. To end the recording (LOG) and
continuous
data transfer operations (SERIAL with
an interval greater than 0), press the same key again.
6)
Sleep_Mode_LOG (Automatic turning off during recording) (only HD21...4.2):
this
function controls the instrument's automatic turning off during logging, occurring between
the capture of a sample and the next one. When the interval is lower than 60 seconds, the
instrument will always remain on. With intervals greater than or equal to 60 seconds, it is
possible to turn off the instrument between loggings: it will turn on at the moment of
sampling and will turn off immediately afterwards, thus increasing the battery life. Using the
arrows select
YES
and confirm using
ENTER
in order to enable the automatic turning off,
select
NO
and confirm to disable it and keep the instrument on continuously.
Note:
even if
Sleep_Mode_LOG=YES
is selected, the instrument does not turn off for less
than one minute intervals.

: to set the current minutes. In order to correctly synchronize the
minute, it is possible to reset the seconds by pressing the UNIT key. Use the arrows to set
the current minute plus one, and as soon as that minute is reached press UNIT: this
synchronizes the time to the second. Press ENTER to go onto the next item.
