*3 The conversion speed indicates how long it takes the value of measured
temperature to be stored into the buffered memory at sampling. Regardless
of the number of channels permitting the conversion, the value of measured
temperature resulted from all channels is stored into the buffered memory
per 320ms.
*4 The output at detecting wire break has a choice among "Upscale",
"Downscale" and "Given value".
