Temperature Monitor

This tab displays the temperature reading from the selected

device as well as the status of the alarms. This tab includes five

control options (see Figure 8):

• Temperature Threshold

• Temperature Value

• Set Temperature Limits

• Log Data

• Temperature Values

Temperature Threshold

If the temperature goes above or below the high and low limits

defined in the Set Temperature Limits section or above the

critical threshold, the Temperature High Limit Threshold,

Temperature Low Limit Threshold, and Temperature Critical

Threshold indicators appear green.

Temperature Value

This displays the actual ADC temperature in twos complement

and degrees Celsius respectively.

Set Temperature Limits

This section allows you to update the high, low, critical, and

hysteresis limits. These ADC values are loaded into the device.

Because the conversion format is twos complement, any value

over 4095 is a negative number. To change the value, you can

use the arrow keys or type a number in the box to update the

limits. The graph labeled Temperature Conversion Measurement

displays the variation in time of the high and low temperature

limits as well as the current temperature in twos complement

format. At startup, the evaluation software initializes the tempera-

ture limits registers (THIGH, TLOW, TCRIT, and THYST) to the default

values shown in Figure 6.
