The command operates like LCP1, but can take up to eight reading/
reference pairs. If there are three pressure barometer modules installed,
the commands MCP1, MCP2, and MCP3 will be available. First
deactivate the previous corrections by using the MPCP1 OFF
command. Precalibration of the transmitter then gives the required
corrections. When entering new multipoint corrections, always start at
the low-pressure end and then go up the pressure range. Key in the
multipoint corrections for each barometer module separately.
MPCP1 [x/y] [z]
Example:
>mpcp1
1. Reading ? 980.1
1. Reference ? 980.0
2. Reading ? 999.8
2. Reference ? 1000.0
3. Reading ? 1020.2
3. Reference ? 1020.0

8. Reading ? 1100.1

NOTE The new multipoint corrections will always cancel the previous
corrections as well as the valid date of calibration of the transmitter.
