If this happens, check that the evaluation board is correctly
connected, that D1 is lit, and try again.
There are three tabs at the top of the program window:
General, Readings, and Settings. These can be used to access
the various functions of the software.
The General tab shows the software version.
Temperature Reading
The Readings tab allows the temperature to be displayed as a
rolling graph. Measurement limits are also displayed for the
AD7414 only. To view the graphic data in more or less detail,
move the arrow pointers on the x-axis and y-axis to zoom in or
zoom out (see Figure 4).

You can select or enable/disable various options within this
dialog box, including the following:
Power Up/Power Down.
Alert Polarity (AD7414 only).
Active Low. Alert Diode D2 is lit when an overtemperature
condition happens (current temperature reading higher
than the temperature set by the blue slider).
Active High. Alert Diode D2 is lit when an under-
temperature condition happens (that is, when the current
temperature reading is lower than the temperature set by
the grey slider).
Bypass SCL/SDA Filter. Switching off the input filters
improves the transfer rate but has a negative effect on the
EMC behavior of the device.
Disable Alert (AD7414 only).
Data Logging
The Settings dialog box also allows you to log data into a file.
