On the left-most position of the Visual Display tab is the
bargraph control/indicator. T his 3D-type indicator gives a
visual indication of the selected temperature channel. T he
bargraph also has 2 moveable controls; these control the
upper and lower interrupt limits which may be set for each
temperature channel. Once the temperature moves outside
these limits, an interrupt will be generated if the interrupt
source is unmasked in the Interrupt Mask Register (please
refer to the ADM1022 datasheet for more detailed inter-
rupt information).
Each temperature channel’s limits may be adjusted inde-
pendently of the next channel, by selecting the channel
from the bargraph panel on the Visual Display tab. T he
channel may be selected by clicking on it, and will turn
green to indicate its selection.
T he temperature value is displayed below the bargraph,
allowing absolute readings to be monitored. T he bargraph
gives a useful indication of whether temperature is rising
or falling, and the rate at which it is doing so.
If the temperature goes outside the programmed limits, an
error is generated for that channel, and the bargraph panel
will give a visual indication of this.
As shown above, when the temperature goes beyond a
programmed temperature limit (86°C in this case), an
interrupt is generated and the LED lights up for that
channel. External 1 is the channel being displayed, since
the label is green. T he absolute temperature on that chan-
nel is 112°C, as shown at the base of the temperature
bargraph.

T he ADM1022 can control the speed of a fan connected
to it. T his tab contains a slider control to manually adjust
the default fan speed.
