Satellite XT 4-20 mA Versions
Current Output
The 4-20 mA signal output range of the instrument is
preprogrammed to correspond to the nominal range
of the target gas with 4 mA representing the zero
concentration and 20 mA representing the full scale
concentration.
This submenu provides the possibility to perform
functional tests and to scale external control systems.
To select a submenu actuate the <set> key to enter or
use the cursor keys <up> and <down> to move back-
wards or forwards.
Set 0 mA

0 mA set !
An analog signal output of 0 mA is now transmitted to
external control systems. Use the <esc> key to exit.
Set 4 mA
Allows the user to scale external control systems with
an output signal of 4 mA representing the zero
concentration value.
Use the <set> key to enter.
