take to complete the command and have data available in its buffer.

The Write User Offset Command loads the "Users Units Offset" coefficient term. The new value
is stored in non-volatile EEPROM within the sensor. With the new offset value now written into
EEPROM, a copy of this value is placed in the sensor data buffer for verification. The
verification is carried out by using the "D" command. To verify the "User Units Offset" at any
other time use the "Read User Units Offset" command.
