If a coordinate is created in a prohibited area or you want to

move it to such an area, the mouse cursor turns into a

no-entry sign. The coordinate jumps automatically back to its

previous position when you let go.

Changes to the graphical view are automatically updated

when you switch to the tabular view, and vice versa.

Ramp close statements

Each segment (ramp) of a tempering profile must

end with a close statement and be linked to the next

segment. These positions are represented by the blue

dots.
To run the selection dialog, move the

mouse cursor to one of the blue ramp end points and

press the right mouse button. The following ramp

close statements are available:

►

normal:

Resets the end point definition back to the standard value. At the

end of the ramp segment the oven continues straightaway with

the next ramp segment. If this is the final ramp segment, the

tempering profile is stopped and the connected oven is reset to

its default configuration.

►

spwt()

(= Setpoint wait). The oven waits for the end of the ramp seg-

ment until the required setpoint has approximately been reached.

Only then is the next segment processed. This command cannot

be applied for the final ramp segment of a tempering profile.

Which setpoint is involved depends on the oven, and can be

seen from the expression in brackets: spwt(t) = Temperature,

spwt(h) = Humidity, spwt(p) = Pressure etc.

Temperature for incubators (Ixx, INCO 2, IPP, ICP) and HCP humid-

ity chambers:

If this function is enabled, the next ramp only begins when the

setpoint temperature has been reached with a tolerance of

± 0.5° C.
Temperature for universal ovens, sterilisers and

Temperature for universal ovens, sterilisers and vacuum ovens:

If this function is enabled, the next ramp only begins when the

setpoint temperature has been reached with a tolerance of

± 2.0° C.
Vacuum for VO vacuum ovens:

If this function is enabled, the next ramp only begins when the

setpoint vacuum has been reached with a tolerance of ± 3 mbar.

For VO vacuum ovens, the SPWT function can be enabled sepa-

rately for temperature and vacuum.
Humidity for HCP humidity chambers:

Humidity for HCP humidity chambers:

If this function is enabled, the next ramp only begins when

the setpoint humidity has been reached with a tolerance of

± 2 % rh. For HCP humidity chambers, the SPWT function can be

enabled separately for temperature and humidity.
