Operating Instructions

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)
Related Parameters 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)
Maximum mA limit (2.6.5.)
Prevents the mA output from rising above this maximum level for a measurement value. This
does not restrict the Fail-safe or Manual settings.
Values Range: 3.8 to 20.50 (mA)
Default: 20.50 (mA)
