1 byte 1 byte
0x01 (*)
(*) The precision field is used only for the modules :
- WaveTherm – PT100
- WaveTherm – PT1000
The WaveTherm – DALLAS doesn't support the precision capability. In this case the precision field
doesn't exist (size = 0 byte).
Thus, the format of the reponse varies according to the module used :
