Temperature compensation related commands
The build in temperature compensation is controlled with three variables. Once the temperature com-
pensation is started, the temperature is saved and continuously compared to the current temperature.
If the difference ∆
T
exceeds the set variable TCOMP DELTA and the time since the last compensa-
tion movement exceeds TCOMP PERIOD, the focuser will move ∆
T
·
TCOMP FACTOR.
The temperature compensation may also be paused (while still keeping track of the temperature
change).
The sensor used for the compensation can eb set to either one of the two possible sensors or the average
temperature of both.
