1.2.1.1 Style. The type designation is identified by the four digit symbol "2RV7". The first three digits identify a
dual ganged (2 cup) composition, variable resistors and the digit identifies the size and power rating of both cups.
1.2.1.2 Bushing. The type of bushing is identified by a single letter in accordance with MIL-PRF-94.
1.2.1.4 Temperature and moisture-resistance characteristic. The temperature and moisture resistance
characteristic is identified by a single letter in accordance MIL-PRF-94.
1.2.1.5 Operating shaft. The operating shaft styles and lengths are identified by a two digit symbol. The first letter
indicates operating shaft in accordance with MIL-PRF-94, and the second letter indicates operating shaft length, as
specified in table I.
1.2.1.6 Resistance. The nominal resistance value expressed in ohms is identified by a three digit number. The
first two digits represent significant figures and the last specifies the number of zeros to follow. The first three digits in
the PIN indicate the value of the resistor cup nearest the mounting surface and the next three digits indicate the
resistance value of the second cup.
