HISTory:TEMPerature[:HISTogram]?
<
slot
>[,MIN|MAX]
HISTory:TEMPerature[:HISTogram]? <slot> returns the histogram data held for the
specified <slot>. Ten values are returned for the amount of time the <slot>’s
temperature spent in ten different temperature ranges. Those temperature ranges can
be queried with the MIN and MAX optional parameter. The units of the time values
returned are HOURs by default, but can be changed with the
HISTory:UNIT[:TIME]
command. The units returned for temperature ranges queried with the MIN or MAX
parameters are an integer values in tenths of a degree Celsius (0.x
°
C).
