Table 6-1: Analog Output Signals Settings & Operation Modes
Dual channel instrument:
Pressing the key while any line is selected
returns to the optional gas component selec-
tion menu to open the same menu for the
other measuring channel.
Press the LEFT key to return to the ANALOG
SIGNAL SETUP screen, enter the "Scaling.."
line and select the channel to setup (multi-
channel instruments only).
Enter the gas concentrations generating ana-
log output signals according the lower
respectively upper range (4(0) or 20 mA). By
default the gas concentrations comply with the
measuring ranges. Setting other
concentrations allows to limit the output signal
range to a concentration level range smaller
than full scale.
Scaling
0/4mA: 0.0000 ppm
20mA: 2000.0 ppm
