STORING AND TRANSFERRING DATA TO A PERSONAL COMPUTER
The HD2106.1 and HD2106.2 instruments can be connected to a personal computer via an RS232C
serial port or USB 2.0 port, and exchange data and information through the DeltaLog9 software
running in a Windows operating environment. Both models can send in real time input measured
values directly to a PC, through the PRINT function; the HD2106.2 can also store the values
measured by using the
Logging function (LOG key) in its internal memory. If necessary, the data
stored in the memory can be transferred to a PC later.

FUNCTION
-
ONLY FOR
HD2106.2
The Logging function allows the recording up to 36.000 data pair measurements [T-
χ
] registered by
the probes connected to the inputs. Logging always includes two parameters. Each data pair is com-
posed of: temperature in °C or °F, conductivity or resistivity or TDS or NaCl. The time interval be-
tween 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 continuous block of samples. The logged parameters are selected using the “°C/°F” and “
χ
-
Ω -TDS/ESC” keys”.
See the description of the menu items on page 10.
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
-
ONLY FOR
HD2106.2
To clear the memory use the Erase Log function (MENU >> SERIAL).
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.
