The instrument has an Auto-Hold function, which can be set in the MENU, that "freezes" the meas-
urement automatically when it has been stable (
within 1 digit
) for over 10 seconds: the message
HOLD is displayed.
To perform a new measurement, it is necessary to press the FUNC/ENTER key.
The HOLD message starts blinking, while the display follows the actual measurement trend, until it
stabilizes again and the HOLD message remains still.
In the menu, the key clears or cancels the active function (ESC).
REL/
key
In measurement mode, it displays the difference between the current value and that measured on
pressing the key. The
REL
message appears on the display; press the key again to return to the
current measurement.
When used in the menu, it decreases the current variable value.
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 (only HD2106.2)
: 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 33).
2)
Print and log interval
: 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.
3)
Sleep_Mode_LOG (Automatic turning off during recording) (only HD2106.2):
this
function controls the instrument's automatic turning off during logging, occurring between
