age and display flashes. The actual sensor supply voltage of the device
U-LOW
is formed automatically based on the ´Minimum sensor supply voltage´ needed
for all sensors; in the menu ´Settings´  ´Power supply´ it can be checked and
also raised to a higher value.

13.2.14 Channel compensation

In the menu ´Channel functions´ - ´Channel compensation´ all forms of com-
pensation, e.g. temperature compensation (see 12.2.5), atmospheric pressure
compensation (see 12.2.6), cold junction compensation (see 12.2.7) are listed
for each channel with the appropriate values which are used for calculating the
measured value. These can be programmed or internally measured values
(see 13.6.4) or also externally measured values (see 12.2.5, 12.2.6, 12.2.7).

13.3 Display settings

Certain settings, especially scaling, are required for bar chart and line graph
displays. These settings have already been described in 11.2 and 11.3. How-
ever, they can also be accessed here.

13.4 Data logger settings

The settings for the data logger have already been described in Chapter 10.
However, they can also be accessed here via ´Settings´.

13.5 Output modules

Data logger ALMEMO ® 710 has three output sockets, A1, A2, A3 (2); these
can be used to output measured values in analog or digital form or as an alarm
signal. It is also possible to initiate various functions by means of trigger
pulses. To cover all possibilities while also keeping the required hardware to a
minimum all necessary interfaces have been integrated in the ALMEMO ® out-
put connectors or output modules.
These output modules and a mains adapter connected at the DC power supply
socket are automatically recognized, just like the sensors, and are initially dis-
played as a list in the menu ´Output modules´.
With the relay trigger analog modules certain function variants can be config-
ured (see 13.5.2), relays can have certain limit values assigned to them (see
7.5), and analog outputs can be assigned to certain measuring channels. In
subsequent menus all ports can be selected and configured accordingly. The
connection possibilities are described in the instructions for the output module
concerned.

13.5.1 Data cables

Via the serial interface it is possible to output cyclic data logs, all the function
values from the measuring menus, and all the programming details for the de-
vice and for the sensors to a printer or computer. The various ALMEMO ® data
