1.3 Substitutions. -1 through -12 indicators are replaceable by the equivalent -100 series indicator (i.e. - a -1 indicator is replaceable by a -101 indicator). The units are mechanically, electrically and dimensionally the same except for the mechanical and thermal shock limits as given in table I.
2 REQUIREMENTS
2.1 Dimensional. The indicator shall conform to the dimensions given in figures 1 through 5 as required.
a. All dimensions are in inches.
b. Tolerances, unless otherwise specified, are ± 0.015
2.2 Weight. The indicator shall not exceed 0.1 ounce.
2.3 Time range. Total readout shall be in accordance with table I. The time scale shall be 0.650 inches long and have 20 equal divisions as shown in figure 1.
2.4 Operating temperature range. -20°C to 85°C. The indicator may also be used in equipment with an operating range of -55°C to 85°C with accurate operation above -20°C.
2.5 Storage temperature range. -80°C to 85°C.
2.6 Power consumption. Power consumption at the rated voltage per table I shall not exceed 50 milli-watts.
2.7 Life accuracy. Accuracy shall be ± 3% for -1 through -12 and ± 5% for -101 through -112 from -20°C to 85°C over the following conditions:
MS90386-1-3-5-7-101-103-105-107: 115Vac ± 13Vac, 50 HZ to 2400 Hz
MS90373-2-4-6-8-102-104-106-108: 23Vdc to 29Vdc
MS9.386-9-10-11-12-109-110-111-112: 4.95Vdc to 5.05Vdc
2.8 Color. The indicators shall be of the following colors:
a. Faceplate - black
b. Numerals - white on black background c. Scale - black on white background
2.9 Test terminal cap. The test terminal cap shall be made of polytetrafluroethylene (PTFE).
3 TESTS AND CHECKS
3.1 Mechanical shock. Indicators shall be tested in accordance with MIL-STD-202, Method
213. Test conditions shall be:
a. -1 through -12 - condition A (50g, 11ms)
b. -101 through -112 - condition C (100g, 6ms)
