Design Analysis H-522 - Write User Units Slope Command; Write User Units Offset Command; Read User Units Slope Command

XL™ Series SDI-12 Operations 14-25
Example of a "Write User Units Slope" command:
Command Response Time Values Description
---------------- -------------------- ------ ------- -----------------------------
"aXWS1.234!" "a0021<cr><lf>" 2 sec 1 Write user units slope
coefficient
14.7.10 Write "User Units Slope" Command
The Write User Units Slope command loads the "User Units Slope" coefficient term. The new
value is stored in non-volatile EEPROM within the sensor. Once the new slope term is written to
the EEPROM, a copy is sent to the sensor data buffer for verification. This data can be viewed
by using the "D" command. To verify the current "User Units Slope" any other time, use the
"Read User Units Slope" command.
Command Response Description
------------- ------------------------- ---------------------------
"aXWSddd!" "atttn<cr><lf>" Write User Units Slope coefficient
Where:
a Is the sensor address ("0" to "9", "A" to "Z", or "*").
XWS Are upper-case ASCII characters.
ddd Is the new User Units Slope value. The input format is very flexible. Some
examples are shown below.
20.095
0.195
7.984E+10
167.824E5
005.9357E-7
500
ttt Is a three digit integer (000-999) specifying the maximum time, in seconds, the
sensor will take to complete the command and have data available in its buffer.
n Is a single digit integer (0-9) specifying the number of values that will be placed in
the data buffer.
