The "Analog Output 2(3) Parameter" and "Analog Output 2(3) Scaling" fields
only appear after activation of the "Use first analog output module" checkbox
and when an AO module is plugged in (standard on DUSTHUNTER T100 and
DUSTHUNTER T200).

Output Error
current
Yes
Error current is output.
No
Error current is not output.
Error Current
Value < Live Zero (LZ)
or > 20 mA
mA value to be output in "Malfunction" state (error case) (size
depends on connected evaluation system).
Current in
maintenance
User value
During "Maintenance", the value entered in the "Maintenance
current" field is output.
Value measured last
The value measured last is output during "Maintenance"
Measured value output The current measured value is output during "Maintenance".

Modules
Use first analog

Inactive
Not permitted for DUSTHUNTER T100/T200 (results in error, because
AO 2 and AO 3 are available by default).
Active
Opens the fields to set parameters for AO 2 and AO 3 (standard on
DUSTHUNTER T100 and T200)

Live zero
Zero point
(0, 2 or 4 mA)
Select 2 or 4 mA to ensure being able to differentiate between
measured value and switched off device or interrupted current loop.

Inactive
Control values (
p. 15, §2.1.3) are not output on the analog output .
Active
Control values are output on the analog output (the "Output control
values at AO" checkbox in the "Adjustment / Function Check -
Automatic" directory must be activated).
