STORING
AND
TRANSFERRING
TO
A
PERSONAL
COMPUTER
The HD3409.2 instrument can be connected to a personal computer via an RS232C serial port, and
exchange data and information through the DeltaLog9 software (Version 2.0 or later versions)
running in a Windows operating environment. The measured values can be sent directly to the PC,
through the
SERIAL
function in real time, or stored in the internal memory using the
Logging
function (LOG key). If necessary, the data stored in the memory can be transferred to a PC later.
T
HE LOGGING FUNCTION
The
Logging
function allows the recording up to 18.000 data pair measurements [T-O
2
] ] registered
by the probes connected to the inputs. Logging always includes two parameters. Each data pair is
composed of: temperature in °C or °F, dissolved Oxygen concentration (in mg/l) or saturation index
(in %) or barometric pressure (in mbar).
The logged parameters are selected using the “°C/°F” and “mg/l-%”. The time interval between two
consecutive measurements can be set from 1 second to 1 hour.
The logging starts by pressing the
LOG key and ends by pressing the same key again
: the data memorized in this way form a con-
tinuous block of samples.
See the description of the menu items on page 6.
If the automatic turning off option between two recordings (MENU >>
Sleep_Mode_LOG
)
is en-
abled, upon pressing the LOG key the instrument logs the first data and turns off. 15 seconds before
the next logging instant, it turns on again to capture the new sample, and then turns off.
The data stored in the memory can be transferred to a PC using the DUMP LOG command: MENU
>> LOG. During data transfer the display shows the message DUMP; to stop the data transfer press
ESC on the instrument or on the PC.
C
LEARING THE MEMORY
To clear the memory use the Erase Log ( MENU key >> using ENTER select the “LOG DUMP OR
ERASE” >> SERIAL key).
The instrument starts clearing the internal memory; at the end of the operation, it goes back to nor-
mal display.
NOTES:
•
Data transfer does not cause the memory to be erased; the operation can be repeated as many
times as required.
•
The stored data remain in the memory independently of battery charge conditions.
•
In order to print the data to a parallel interface printer, you must use a parallel-serial adaptor (not
supplied).
•
The direct connection between instrument and printer via a USB connector does not work.
•
Some keys are disabled during logging. The following keys work: ON/OFF, FUNC (Max-Min-
Avg) and SERIAL.
•
The recording started with the display in Max-Min-Avg mode proceeds normally with the actual
measured values. Only the display shows respectively the Max, Min or Avg values.
•
The logging is disabled, if the Auto-HOLD function is enabled.
•
If the logging is started when the display is in REL mode, the relative values are logged.
•
It is possible to activate both the logging (LOG) and direct transfer (PRINT) functions at the
same time.
