Analog outputs
Menu: Parameter/I/O/Analog output
This menu checks the analog outputs.
Select the analog output to be tested and click “Test”.
Figure 29: Test of analog outputs
Significance
1
Number of selected output.
2
Topographic addressing.
3
Test value.
Input: Nominal value of the current to be output.
4
Actual value of the current output.
5
Output value converted to the physical unit.
b
Select the analog output to be tested and click “Test”. The current test current is
shown in the menu.
b
To change the test current on the analog output, modify the value “Test value
[phys. unit]”. The test value [phys. unit] always refers to the active output range of
the analog output. To check the settings for the analog outputs, go to: “BCU/Para‐
meter/I/O/Analog outputs”.
b
Use an ammeter to check the analog output values directly on plug X7.
Example (with 2 measuring ranges set):
Range 1 = 0 - 200 ppm
Range 2 = 0 - 400 ppm
LiveZero = 4 mA

Adapting the hardware
NOTE
You have to perform this work when deviations of the analog signal are detected during
the hardware check. Analog inputs and/or analog outputs must then be adapted.
Tools required
Ammeter
Constant current source or analog output
