SERIAL/EraseLOG key
In measurement mode, this function starts and stops the data transfer to the RS232C serial output
According to the settings entered in the
Print and log interval menu item, a single sample can be
printed if Print and log interval = 0 or a continuous indefinite printing of the measured data can be
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
battery symbol;
when using an external power supply the battery symbol does not appear .
Press SERIAL to end the continuous printing.
Before starting the printing with SERIAL, set the baud rate. To do so, select the
Baud Rate menu
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.
If you
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.

°C/°F key
When the temperature probe is connected, the measured value is used to compensate the conductiv-
ity measurement; the key changes the unit of measurement from degrees Celsius to Fahrenheit.
If the probe is not present, the compensation temperature must be entered manually: to manually
change the value shown in the display lower line, press °C/°F once. The temperature indicated starts
blinking. While the display is blinking, it is possible to change the compensation temperature using
the arrows (
and ). Confirm using ENTER. The display stops blinking, and that temperature is
used for compensation.
If the temperature probe is not present, to change the unit of measurement between °C and °F, it is
necessary to press
twice the °C/°F key.
Up Arrow
When used in the menu, it increases the current variable value. During measurement, if the tempera-
ture probe is not present, it increases the temperature value for conductivity compensation.
