When the logging function is on, the LOG indication is displayed, the battery symbol blinks and a
beep is issued each time a logging occurs;
the battery symbol does not appear when using an
external power supply .
To end the logging, press LOG.
If the Auto-HOLD function is enabled (please see the menu), the data logging is disabled.
The HD2109.2 can turn off during logging between one capture and the next: the function is con-
trolled by the
Sleep_Mode_LOG parameter. When the logging interval is less than one minute, the
logging instrument remains on; with an interval of at least one minute, it turns off between one cap-
ture and the next if the parameter
Sleep_Mode_LOG =YES.

set up if Print and log interval =1…3600.
The printing operation is accompanied by the display of the RS232 symbol and the blinking of the

Before starting the printing with SERIAL, set the baud rate. To do so, select the

item and select the maximum value equal to 38400 baud by using the arrows. Confirm by pressing
ENTER.
The DeltaLog9 software for PC will automatically set the baud rate value during connection.

are using a different program than DeltaLog9, be sure the baud rate is the same for both the
instrument and the PC: the communication will only work in this way.
