Parameters
2.6.2. Start of Scale (4 mA Setpoint)
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.)
• 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.
2.6.3. Full Scale (20 mA Setpoint)
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.
)
• 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
.
2.6.4. Control Range: lower limit (Min. mA limit)
Prevents the mA output from dropping below this minimum level for a
measurement value. This does not restrict the Fail-safe or Manual settings.
2.6.5. Control Range: upper limit (Max. mA limit)
Prevents the mA output from rising above this maximum level for a
measurement value. This does not restrict the Fail-safe or Manual settings.
