HD21AB and HD21AB17 can be connected to a personal computer via an USB port, and exchange
data and information through the DeltaLog10 software (from version 0.1.5.3) running in a Windows
operating environment. It is possible to store the measured values in the internal memory using the
Logging function (MEM key). If necessary, the data stored in the memory can be transferred later to
a PC.
5.1.1 Logging Function
The Logging function allows recording of the measurements. The time interval between two
consecutive measurements can be set from 15 seconds to 1 hour. The logging starts by pressing the
MEM key and ends by pressing the same key again: The data memorized in this way form a
continuous block of data.
See the description of the menu items on chapter “
4. MAIN MENU ”.
If the automatic turning off option between two recordings (see par. 4.2.2 AutoPowerOff–
AutoPowerOff Mode ) is enabled, upon pressing the MEM key the instrument logs the first data and
turns off. 1 minute 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 through the DeltaLog10 software (from
version 0.1.5.3). During data transfer the display shows the message DUMP; to stop the data
transfer press ESC on the instrument or on the PC.
5.1.2 Clearing the memory
To clear the memory use the Erase Log function (see par. 4.2.5 Log File Manager ). The instrument
starts clearing the internal memory; at the end of the operation, it goes back to normal 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 the battery charge conditions.
•
The direct connection between instrument and printer via a USB connector does not work.
•
Some keys are disabled during logging . The following keys are enabled: MEM , MENU , ENTER
and ESC .
•
Pressing the MEM and MENU keys has no effect on the logged data if these keys are pressed
after starting the recording, otherwise the following is valid.
5.1.3 Print function
Press ENTER to send the measured data directly to the USB port, in real time. The printed data
units of measurements are the same as those used on the display. The function is started by pressing
ENTER .
The time interval between two consecutive prints can be set from 15 second to 1 hour (please see
the
Print interval menu item at par. 4.3.1 Print Interval ). If the print interval is equal to 0, by
pressing ENTER a single data is sent to the connected device. If the print interval is higher than 0,
the data transfer continues until the operator stops it by pressing ENTER again.
