MBFI-2 Environmental Test Schedule

The following schedule was used to conduct environmental testing, relative to humidity and temperature cycling, on a Multiplex Bus Fault Isolator Serial Interface Assembly

Static Test (UUT OFF)

Hold UUT at –41C for 2 hours.

Let UUT’s temperature rise to room temperature.

Apply power to UUT; after 15 minutes on--calibrate and self-test.

Hold UUT at +71 C for 2 hours.

Let UUT’s temperature fall to room temperature.

Apply power to UUT; warm for 15 minutes; calibrate and self-test.

The environmental chamber was programmed for three humidity levels at every temperature increment; however, below 0 C the chamber did not realize any humidity.

The following values of resistors were measured discretely with a Hewlett-Packard 34401A digital multimeter:

3.502, 75.03, 1.002K, 1.023M, 10.02M , & 107.7M. The resistors were soldered to a cable to facilitate testing in the environmental chamber, and with the additional cable lead resistances were measured with the same Hewlett-Packard 34401A digital multimeter: 3.892 , 75.43 , 1.002K , 1.001M

, 10.001M , and 105.9M . The latter values are more valid since the contacts were improved with soldered connections, and this was the final configuration.

TESTING RESULTS

Date To establish a baseline the Serial Interface Box (SIB) was used to measure the six resistors configured for the environmental test.

The SIB was warmed for 15 minutes and passed self-test. The SIB was calibrated with ST1 on the end of TC3.

The first measurements recorded for the baseline were measured using the single-measurement mode. The second group of measurements was recorded using the continuous mode where a minimum, maximum, and mean are automatically reported by the MBFI Manual Test software. The six resistors were measured (three times):

The SIB was then cooled and heated to the limits of the environmental chamber to determine effects of extreme temperatures on measurement accuracy.

Date (-41.1 C)

SIB was cooled to -41.1 C for 2 hours. It was then warmed to room temperature, powered and allowed to warm for 15 minutes. It passed self-test and calibration and the resistors were measured:

Temperature Pyramid – 0% Relative Humidity – SIB Calibrated at Each Temperature

A temperature pyramid (-30 C to +60 C and back to -30 C) was programmed into the environmental chamber. The temperature was ramped up and down in 15 degree increments, and the SIB was held at each temperature for 20 minutes and self-tested. The SIB was calibrated at each temperature. The resistance and impedance were measured and recorded (the first column for each temperature is resistance in ohms; the second column is impedance in ohms):

Analysis

In the preliminary testing where the SIB was heated and cooled to the limits of the environmental chamber, a comparison of the resistors reveals an insignificant change in measurement accuracy after the extreme temperature conditioning.
