3. Remove the load resistors (pull on the black plastic tab, shown in Figure 5-11). Observe the currents (3.3 V, 5.0 V,
and +12 V) in the PSU Supply panel on the Board Status tab.
Figure 5-11. Load Resistors
4. Observe the graph as the load is removed. Note the current goes to 0 mA.
5. Compare the readings in the Board Supply and PSU Supply panels to their corresponding graphs in the Graphs tab.
Temperature Monitoring
Observe the board temperature in real-time in the Board Status tab in the System Management software (all except
battery temperature).
To observe the copper pad (finger pad) temperature:
1. Hold your finger on the copper pad (Figure 5-12).
Figure 5-12. Finger Pad
2. Observe the finger pad temperature in real-time in the Board Status tab. Also observe the graph in the Graphs tab.
You may have to scroll down to view the finger graph.
Note: The finger pad may take several minutes to heat up due to body heat, but it should reach around 38.5°C.
When you remove your finger, the pad will take much longer to cool down due to lack of direct cooling, but
will reach room temperature.
RTC Control
The real-time clock (RTC) is the clock used on the board, which keeps track of the current time. It is possible to
synchronize the on-board clock with the PC's clock through the following setup.
To set up the RTC:
1. To set the RTC from the PC, click the Set from PC button in the Board Status tab.
2. You can view the board's time stored in the real-time clock on the System Event Log in the Event Log tab.
Logging Events
The System Event Log available on the Event Log tab can be used to record the incoming captured data from the board.
