In the menu, the ENTER key confirms the current parameter and then goes to the next one. Pressed
together with the ON/OFF key, disables the automatic turn off.
MENU Key
The first menu item is accessed by initially pressing on the MENU key; press ENTER to go to the
following items. To modify the item displayed, use the arrow keys (
and ). The current value is
confirmed by pressing the ENTER key and the display moves on to the next parameter. If pressing
ESC the setting is cancelled.
To exit the menu, press the MENU key at any time.
The menu items are listed in this order:
1) Management of memorized data : the message " LOG_DUMP_or_ERAS " (Transfer data
or erase) is scrolled in the comment line. The center figure reports the number of free mem-
ory pages (FREE). All memory data are permanently erased by pressing SE-
RIAL/EraseLOG. 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 30).
2) sets the interval in seconds between two loggings or data transfers to the serial port. The in-
terval can be set from 0s, 1s, 5s, 10s, 15s, 30s, 60s (1min), 120s (2min), 300s (5min), 600s
(10min), 900s (15min), 1200s (20min), 1800s (30min) e 3600s (1 hour).
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.
3) Sleep_Mode_LOG (Automatic turning off during recording : ) : 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 in-
strument between loggings: it will turn on at the moment of sampling and will turn off im-
mediately afterwards, thus increasing the battery life. Using the arrows select
YES and con-
firm 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.
4) Identifier of the sample being measured it is an automatically increased progressive num-
ber associated with the single PRINT function ( print interval set to 0 ) for the printing of
labels. The index appears in the single sample printing together with date, time, conductivity
(liquid resistivity, total dissolved solids or salinity) and temperature. This menu item allows
