d. Surge and transient voltage protection. The test set microprocessor board shall contain surge and transient voltage protection internal of the enclosure. The transient voltage protection circuit shall be so designed as to prevent electronic device damage within the system per type III solid-state tolerance bands of MIL-T-28800, the surge voltage protection circuit shall conform to ANSI/IEEE Std. C62.41-1980; 2.SKY, category A. The surge protection circuit shall drain excess power due to surges directly to the ground conductor for personnel protection. Normal operation of the digital signal generator may be inhibited and false operational signals may be generated under input voltage transients greater than ± 20 percent and frequency transient conditions greater than ± 5 percent from within the nominal type III steady-state tolerance bands of MIL-T-28800, damage (other than fuse failure) to the meter shall not occur during voltage transient conditions greater than ± 20 percent and frequency transient conditions greater than ± 5 percent within the maximum limits (30 percent voltage transients and 10 percent frequency transients) specified in MIL-T-28800. Normal operation of the meter shall be automatically resumed when the transient has passed and any blown fuses are replaced. Blown fuses shall be externally accessible. Testing shall be in accordance with MIL-T-28800.
5. Dimensions and weight. The size and weight of the equipment shall be consistent with current commercial capabilities, refer to paragraphs 5.a and 5.b of this CID.
a. Equipment dimensions. The nominal dimensions per component for the digital signal generator should be approximately ( ) inches height x ( ) inches wide x ( ) inches deep.
b. Equipment weight. The weight including all accessories (excluding manual), shall not exceed 34 lbs.
6. Enclosure requirements. Unless otherwise specified herein, the equipment shall comply with the style E enclosure requirements of MIL-T-28800.
a. Rackmount. Rackmount capability is not required on this tester.
b. Tilt-bail handle. A tilt-bail handle is not required on this tester.
7. Marking and identification.
a. Marking. The visible surface adjacent to panel facilities such as variable controls, indicators, jacks, connectors and fuse holder(s), shall be marked with a suitable word, phrase, or abbreviation thereof, indicating the purpose or use of the part.
(1) Panel marking. The front panel marking shall comply with the type III parts, materials and processes panel marking requirements of MIL-T-28800; however, marking identification processes other than the type III requirements specified in MIL-T-28800 may be used, provided the marking and identification processes are capable of passing the front panel marking test when tested in accordance with this CID.
