AVO Electronic Test Meter Valve Volt Meter

The high input resistance impedance of the instrument renders it particularly suitable for use upon electronic circuits which are usually capable of supplying very little energy, indeed certainly not enough to drive directly a general purpose moving coil instrument without causing a serious volts drop in the power source. When working with R.F. it is usually particularly important that the circuit under test should not be loaded by the measuring instrument, or losses introduced into the circuit by virtue of capacity and leakage in the instrument. By the use of a novel type of probe this test meter overcomes these and other problems hitherto associated with R.F. testing.
