Analog input zero scale and full scale values
Configure your analog input’s zero and full scale values.
In most cases the output range of the sensor feeding the analog input matches the
hardware limits of your meter’s analog input port. In that case, the analog input’s zero
scale and full scale values are the same as the sensor’s represented range. For
example:
Analog sensor Meter’s analog input Analog input values
0 - 50 psi represented by a
4 - 20 mA signal
4 - 20 mA analog input range Full scale = 50 (psi)
Zero scale = 0 (psi)
If the sensor’s output range does not match your meter’s hardware limits, you must
calculate the full scale and/or zero scale values by analyzing the system.
See the ION Reference, available from www.usa.siemens.com/pds, for detailed
information about the Analog Input module and full scale and zero scale calculations.
Configuring option module analog inputs using ION Setup
You can configure analog inputs using ION Setup.
Analog inputs are available on the optional I/O modules you can connect to the base of
your meter.
Calculate your zero scale and full scale values based on the analog source and the
input range of your meter.
Make sure that the analog input port that you want to use is properly configured and
connected to a valid external analog signal source.
1. Start ION Setup.
2. Open the Setup Assistant for your meter.
3. Navigate to Expansion Module > Option I/O Modules and select the module tab
that corresponds to the option module with the analog input you want to configure.
4. Select the analog input channel and click Edit. The setup screen for that analog
input is displayed.
5. Configure the analog input by selecting the parameter and clicking Edit.
Parameter Value/Range Description
Zero scale 0 to ±10
9
The minimum source value that matches the minimum
analog input signal.
Full scale 0 to ±10
9
The maximum source value that matches the maximum
analog input signal.
Port
–
The physical analog input port connection.
Mode Voltage, current Determines whether the analog input is monitoring voltage
or current.
