2920 Float & Tape Transmitter 5 Display and Configuration Interface
74 Installation and Operations Manual
Display Only Description
Analog Status A value of 1 indicates the analog value is valid and
within range; a value of 0 indicates some the value is
out of range.
Pnt Status Point Status, as follows:
0x0001 - Hardware Failure
0x0002 - Value 1 Over range
0x0004 - Value 1 Under range
0x0008 - AI is uncalibrated
Value A value of 4-20 mA signal with the calibration correction
applied.
Raw Value1 A value of 4-20 mA signal before calibration correction
is applied.
Elapse Time of last update.
Pnt CheckSum CRC-16 Checksum of point's static configuration
parameters.

Config Params
Avg Filter The Analog Input value can be averaged over several
samples to improve stability of the measurement. The
filter can be set between 0 and 7.
Zero
Span
Zero and Span together determine how the input value
is scaled. The Analog input measures a value between 0
and 22 mA. The measurement value in typically in the
range of 4 to 20 mA with 4 mA the minimum value and
20 mA the maximum value. (A 0 to 4 mA and 20 to 22
mA values are generally used to indicate a fault
condition.) If the 4 to 20 mA data came from a level
instrument with a range of 0 to 30 feet, the Zero
parameter would be set to 0 and the Span parameter
would be set to 30.0.
Cal. Point #1
Cal. Point #2
The Analog Input uses a two point calibration points:
Point # 1 is the Calibration Value for 8 mA.
Point #2 is the Calibration Value for 16 mA.
