Command #177: Write Upper Trim Point
Writes the ULTIMA X Upper Trim or Span point value. The ULTIMA Gas Monitor
uses the Upper trim point value to perform Span calibration. When a Span calibra-
tion is performed, the device automatically sets the highest reading obtained to this
Span value. The adjustment range of the Upper Trim Point is from one display unit
to the full scale limit.
