MIL-DTL-15098E
R1 - Resistance divider.
V1 - Voltmeter.
A - Ammeter impedance less than 1 percent of series impedance R2. For AC measurements, use a
thermocouple ammeter or equivalent.
R2 - Series resistor magnitude as specified for lamp under test (see 3.1).
V2 - Voltmeter minimum 10 megohms input resistance.

NOTES:
1. For testing neon and argon indicator lamps, the filter shall be such that the frequency response of the
photomultiplier tube, photometer, or photo cell used in conjunction with a Kopp 5970 filter, or
equivalent, gives a narrow band response peaked at 360 nanometers.
2. Calibrate for light output at 3-month intervals, or less, using calibration lamps versus primary standard
lamps. Sources for primary standard lamps and calibration services are available through the National
Institute of Standards and Technology (NIST).
