Temperature Compensation
This function runs the temperature internally to the nSTEP so a
user can actually configure it and then exit the ASCOM driver,
the nSTEP will keep on 'auto' compensating.
This internal temperature compensation is -not- controlled by
the higher level ASCOM API for temperature compensation, the
higher level API uses the temp comp of the ASCOM driver.
The
internal compensation should not be used if the higher level
API's are used.
Temp Change:
T
his is the temperature change x10 to trigger a compensation.
The nSTEP uses a fixed point value here which is 10X the real
temperature change desired. Examples: -005 = move in "-"
direction when temp changes by 0.5C, +015 = +1.5C change
must be detected before triggering a compensation. The values
can range from -100 (-10.0C) to +100(+10.0C) in increments of
5(0.5C). The sign signifies whether to move + or - steps on a
change.
Temp move:
Move this many steps for each Delta Temp change. Direction of
movement controlled by sign of DeltaTemp
Temp Blash:
Apply this number of steps in last move direction before
reversing direction. Range 0 through 100 with 0 = no backlash
takeup
Temp Timer:
Temperature will be averaged over this number of seconds.
Range 1 to 75 seconds. Set to a lower value for more
immediate changes. A lower value may cause 'hunting' if the
sensor is detecting a value that is just toggling slightly (e.g. from
17.5C to 18.0C to 17.5C).
TC Off
Internal compensation turned off.
TC Manual
Temperature compensation done once on demand. Mutually
exclusive with the ASCOM drivers temperature compensation.
TC Auto
Internal compensation runs all the time. Mutually exclusive with
the ASCOM drivers temperature compensation.
TC Prime
Must press
'Prime for Manual'
then
'SaveT'
to set the device's
current temperature and position so it knows where to start
from. After that, press SaveT while
'Manual'
is set to force a
compensation at the current temperature. Useful for focusers
with backlash when you do not want compensation running in
the middle of an exposure as taking up the backlash will throw
image out of focus even more if direction of motion reverses.
