7.5.2 4–20 mA Span [4_20]
The 4–20 mA settings menu allows the span of the 4–20 mA outputs to be set. The Span value sets the relationship
between the reading on the display and the current output from the 4–20 mA.
For example, if the Span value is set to 100.0 (default), then a display reading of '100.0' will output 20 mA. Display
values >100.0 will be clipped at 20 mA. A reading of '0.000' will always output a value of 4 mA.
Adjusting the 4–20 mA Settings
1. Enter the password, if required (see section 7.2 on page 18).
2. Scroll DOWN to the 4_20 menu heading.
3. Press RIGHT: display shows the span value (default 100.0).
4. Adjust the value then press RIGHT to return to the main menu heading.
NOTE on the range of allowed values:
SPAN: the decimal point is fixed after the 3rd digit. This allows values from 000.1 to 999.9. The 4–20 mA output
has an independent filter (default: 5 s). See below on how to change this.
The 4–20 mA output has an independent filter (the FLTR menu). To change this, refer to the Engineering menu section (see
page 20) for details and instructions.
