13. DEVICE CONFIGURATION

A number of parameters that need to be modi-
fied only very rarely can be specially pro-
grammed in `Device configuration`.
switching ON press and hold down key
. The function field should then show an ab-
breviation for the parameter and the main field
should show the value currently set.
To select the following parameters again press

Automatic switch OFF time for device in minutes
Automatic switch OFF time for display illumination
Atmospheric pressure for pressure compensation
To enter values
To cancel or terminate configuration press

13.1 Device address and networking

To communicate with networked devices it is absolutely essential that all the
devices concerned should have the same baud rate setting (default 9600
baud) but that each should have its own dedicated address; this ensures that
only one device responds per command. Before starting network operation en-
sure therefore that all the measuring instruments involved are assigned differ-
ent device addresses. This is the purpose of the afore-mentioned ´Adr GA´
parameter.
13.2 Device locking
A very useful feature is the ability to lock
equipment against undesired reprogramming.
Sensor parameters are usually protected by
means of sensor locking. (see Manual, 6.3.12)
This status can only be altered via the inter-
face. On this device access to functions and
to various programming options is controlled
by sensor locking and by the locking code; this
can be configured as and when required via menu item ´Loc VC´. Functions
protected by means of sensor locking cannot be selected. All programming
options having a long-term effect can only be accessed using locking code 0.
