Parameters
P713 Echo Lock Window
Adjusts the size of the Echo Lock Window. This value is automatically altered when
Measurement Response (P003), Maximum Fill Rate (P700), or Maximum Empty Rate
(P701), are altered.
The Echo Lock Window is a ’distance window
1
, centered on the echo used to derive the
reading. When a new measurement falls within the window, the window is re-centered
and the new reading calculated. Otherwise, the new measurement is verified by Echo
Lock (P711) before the reading is updated. The distance value of this parameter is given
for a temperature of 20
o
C (68
o
F).
When the value is 0, the window is automatically calculated after each measurement.
The value is fixed at 0 if Echo Lock (P711) is set to 3.
• For slower Measurement Response values (P003), the window is narrow.
• For faster P003 values the window becomes progressively wider.
P752 HART address
Sets the device address or poll ID on a HART network. Any address other than 0 will
cause the output current to be a fixed value, and the current will not indicate the reading.
