4 mA Setpoint (2.6.2.)
Sets the process level corresponding to the 4 mA value. 4 mA always defaults to
0
, and
Current
Output Function (2.6.1.)
determines whether this is a Level, Space, Distance, or Volume
measurement. (See
Current Output Function (2.6.1.)
for an illustration.)
Values
Range: –999999 to +999999 (limits vary with current function and units)
Default:
0.00
m (set to value corresponding to 0% as defined by Current
Output Function)

Units (2.2.1.)
Current Output Function (2.6.1.)
● Enter the reading that is to correspond to a 4 mA output.
● Units are defined in
Units (2.2.1.)
for Level, Space, or Distance. Units are unspecified for
Volume.
20 mA Setpoint (2.6.3.)
Sets the process level corresponding to the 20 mA value. 20 mA always defaults to 100%, and
Current Output Function (2.6.1.)
determines whether this is a Level, Space, or Distance
measurement. (See
Current Output Function (2.6.1.)
for an illustration.)
Values
Range: –999999 to +999999 (limits vary with current function and units)
Default:
20.00
m (set to value corresponding to 100% as defined by Current
Output Function)
Related Parameters
Units (2.2.1.)
Current Output Function (2.6.1.)
● Enter the reading that is to correspond to a 20 mA output.
● Units are defined in
Units (2.2.1.)
for Level, Space, or Distance. Units are unspecified for
Volume.
Minimum mA limit (2.6.4.)
Prevents the mA output from dropping below this minimum level for a measurement value. This
does not restrict the Fail-safe or Manual settings.
Values
Range: 3.8 to 20.5 (mA)
Default: 3.8 (mA)
