3.7.4 Configuration Parameters (Continued)
TDR Config Configures the current output for Near Zone and Lost Echo
conditions
Lost Echo occurs when the unit cannot find a valid level or
the end of the probe and represents an error condition.
Near Zone occurs when a level is tracked into the Upper
Dead Zone. When this occurs the current will go to the
selected value and remain there until the level falls back
into the measurable range
NOTE: If the system is powered on or “signal acquire” is
activated with the level in the Near Zone, it will not be
detected and an erroneous reading may result.
Lost Echo:
Low Current (3.7
mA - Default)
High Current (22
mA)
Near Zone:
Low Current (3.7
mA)
High Current (22
mA - Default)
