Device Specific Status (Byte 0-5) Command 48 returns in byte 0 to 13 additional device status information, which are
described below.
Transmitter
M
Underrange
Measurement is under specified range. Check the
specified lower range and sensor and sensor connection.
If error remains replace the sensor.
Transmitter
M
Overrange
Measurement is over specified range. Check the specified
high range and sensor and sensor connection. If error
remains replace the sensor.
Transmitter
F
