Fan
This test confirms that the internal cooling fan is running.
Real Time Clock (RTC) Battery
The RTC battery provides power for the real- time clock circuitry on the
motherboard when the N432A is powered off.
During the RTC battery test, the RTC battery power level is determined by
converting the ADC value of the RTC battery power level read from the
FPGA, to voltage level. If the battery power level is less than a
prespecified threshold (threshold to be defined later), the test will fail. An
error will be logged in the error list if the test fails.

built- in self- test circuit will output a set of known DC voltages to the
bridge which are then compared to those measured by the N432A
metering. This is a user- invoked self- test.
