4.1.4 AutoCal Program Edit
Pressing the Edit button calls up the AutoCal Program Edit screen.
Figure 14: AutoCal Program Edit Screen
Set-points are programmed in an identical way to the standard Programmer. However, the green
buttons take on a different function; they are now used to determine the adjustment points. Probes
that are selected for adjustment within the AutoCal Screen will be adjusted at points that are selected
here. Only one temperature point can be selected and must be selected as the first adjustment point.
This is because of the way the HygroClip probes work: if temperature is adjusted, corresponding
adjustments for RH are made at the same time. This policy is enforced by the software: greyed out
buttons refer to options that are not possible, a dark green button is a point not selected for adjustment
and bright green is a point selected for adjustment.
Points can be set for a minimum duration of 15 minutes; please ensure sufficient time is allowed for the
probe to stabilise. A duration of at least an hour is strongly recommended, longer for extremes of
temperature or RH. The timing of a set point will begin when the chamber is within the set tolerance.
Take particular care to allow sufficient time to allow for stabilisation of probes with particular filters
applied.
It is not possible to select different adjustment points for different probes. If this is desired, please run
a new program at a later time.
