Status Registers; A.2 Status Registers - Vaisala HMD60 Series User Manual

Integer Values (x100, Non-metric)
392 0187
1) NOTE: 16-bit integers have a maximum value of +32767. Certain measurement parameters
(for example, mixing ratio and enthalpy) can exceed this value in x100 scaling. In such cases,
the value of the parameter is cut off at +32767, and measurements above this value are not
reported. Verify that the measurement ranges in your application are suitable for the 16-bit
integer format with x100 scaling; whenever possible, it is recommended to use 32-bit float
values.
