BALLANTINE NBS MICROPOTENTIOMETER MODEL 440. SERIAL No. 245 For Calibration of AC Voltmeters. Oscilloscopes and Signal Generators. The Ballantine Model 440 Micropotentiometer Is designed to provide a precisely determined voltage at its output terminal when 0 to 900 megahertz current is fed into the input terminal. The input current flows through a UHF-type thermocouple to a radial resistor of known cOl1stant value. The voltage developed across this resistor becomes the standard which is used to calibrate electronic voltmeters. Signal generators, oscilloscopes, and other voltage-sensing devices. The nominal output voltage of a Model 440 is given by the product of the heater current rating of the thermocouple and the resistance of the radial resistor. This voltage can be varied from 1/3 to 1-1/ 3 of the rated out put by varying the thermocouple ... morecurrent over a four to one range. Radial resistors are available in 21 nominal steps from 0.0 I ohm to 22 ohms. Any of these resistors may be plugged into any thermocouple housing assembly having either a 5. 10, 15, 25, or 50 miliamperes UHF thermocouple. To cover the complete range of voltages from 17 microvolts to 1.4 volts.
