Temperature
The remote-diode-measurement channels can provide
11 bits of data (1 LSB = +0.125°C). The 8 most signifi-
cant bits (MSBs) can be read from the local temperature
and remote temperature registers. The remaining 3 bits
for remote can be read from the extended temperature
register. Extended resolution is enabled by checking the
Enable Extended Resolution (0x57) checkbox within
the Temperature tab sheet (Figure 1).
Read a temperature by pressing the Read button. The
temperature (in Celsius) reading is shown to the right of
the GUI.
ALERT and OVERT Temperature Limits
All temperature channels have programmable alert
(ALERT) and overtemperature (OVERT) thresholds. Both
alert and overtemperature limits can be set in the ALERT
Temperature Limit (0x17) and OVERT Temperature
Limit (0x20) group boxes within the Temperature tab
sheet (Figure 1).
Read a limit by pressing the Read button. The value
(in Celsius) is shown in the edit field. Change a limit by
entering the value (in Celsius) into the appropriate edit
field and pressing the Write button.
