4 mA value
Navigation Setup → Advanced setup → Current output → 4 mA value
Description Value for 4-mA at 'Turn down parameter' = On Using the turn down functionality it is
possible to map a section of the measuring range to the total range of the output current
(4-20mA). The section is defined by the '4 mA value' and '20 mA value' parameters.
Without the turn down, the complete measuring range (0 to 100%) is mapped to the
current output (4 to 20mA). Note: If '20 mA value' is smaller than '4 mA value', the current
output is inverted, which means that an increase of the process variable results in a
decrease of the output current.

20 mA value
Navigation Setup → Advanced setup → Current output → 20 mA value
Description Value for 20-mA at 'Turn down' parameter = On Using the turn down functionality it is
possible to map a section of the measuring range to the total range of the output current
(4-20mA). The section is defined by the '4 mA value' and '20 mA value' parameters.

current output (4 to 20mA). Note: If '20 mA value' is smaller than '4 mA value', the current
output is inverted, which means that an increase of the process variable results in a
decrease of the output current.

Trim
Navigation Setup → Advanced setup → Current output → Trim
Description Select action for the recalibration of the current output. The trim can be used to
compensate a drift of the current output (which might be caused by very long cables or by
a connected Ex barrier, for example). Steps of the trim: 1. Select 'Trim' = 4 mA. 2. Measure
the output current with a gauged multimeter. If it is not equal to 4 mA: Enter measured
value in the 'Trim value low' parameter. 3. Select 'Trim' = 20 mA. 4. Measure the output
current with a gauged multimeter. If it is not equal to 20 mA: Enter the measured current
into the 'Trim value high' parameter. 5. Select 'Trim' = Calculate. The device calculates the
new scaling of the output current and stores it in the RAM.
