VACUUM-TUBE VOLTMETER type RV33 1. General Description This vacuum-tube voltmeter is designed to measure a-c voltages both in the sonic, the super-sonic, and the carrier frequency range or wherever there is a demand for a combination of great sensitivity, wide frequency range, and wide voltage range.
Introduction: This vacuum-tube voltmeter combines good sen sitivity, high input impedance, and wide fre quency range. The instrument is weil fit for use in audio-frequency, supersonics, and carrier fre quency work. Due to negative feedback the meter reading will remain virrually unaffecred by line volt age variations. The voltmeter is provided with a

All the vacuum-tube voltmeters, however, are designed to be used in essentially the same manner. Now, to obtain the proper results from a vacuum-tube voltmeter requires not only that the serviceman knows how to connect the meter into the circuit and how to adjust the panel controls, but that he also knows how to correctly read the meter scale.

In 1959, Popular Electronics magazine ran a 5-part series on test equipment usage. This final article is on the use of a vacuum tube voltmeter (VTVM) for making accurate AC and resistance measurements. Also in this edition is a construction article for RCA's VoltOhmyst VTVM kit, so the two compliment each other. Author Larry Klein discusses mainly the AC and ohmmeter functions, providing both ...
1) GENERAL DESCRIPTION This vacuum-tube voltmeter is designed to measure a-c voltages in the sonic, the super-sonic, and the carrier frequency range or where- ever there is a demand for a combination of great sensitivity, wide fre- quency range, and wide voltage range.
VACUUM-TUBE VOLTMETERS Definition—The terms vacuum-tube voltmeter, VT V M, and elec- tronic voltmeter are synonymous and refer to the combination of a thermionic vacuum tube and an indicating meter for the purpose of measuring current, voltage, or resistance.

Type RV13 Vacuum-Tube Voltmeter incorporates a balanced d-c amplifier with an extremely strong negative feedback, a built-in double diode, a diode of special design mounted in a probe, a meter and a regulated power supply.
The type RV35 Wideband Millivoltmeter is a sensitive, wideband vacuum-tube voltmeter with high measuring stability. It is therefore ideally suited as a general purpose voltmeter for laboratory use.
Page 8 RADIOMETER SECTION GENERAL DESCRIPTION The principle of the vacuum—tube voltmeter is illustrated by the block— diagram at the end of this manual. The vtvm consists of two cathode fol— lower stages followed by an amplifier.

4) OPERATING THE VACUUM-TUBE VOLTMETER Connect the probe to the instrument with the six-prong connector, and switch on the line voltage. Shortly afterwards the meter needle will de- flect against stop. This deflection, which will not damage the meter, is due to oscillations in the amplifier during the warm-up period until the stabilized power supply is capable of operating in full. After about ...
