The RF Probe with its full-wave crystal detecting circuit
produces a true RMS response without turnover, or harmonic errors
for all voltage levels below 0.03 Volt, gradually changing to
peak-to-peak reading (calibrated in RMS) at approximately 1.0 Volt.
The probe has a shunt capacitance of approximately 2.5 pF at levels
of 0.3 volt or higher, increasing slightly at levels of 0.1 Volt or
is a variable factor, depending on the voltage and frequency.
A db scale in red on the panel meter and range switch
provides a convenient means of expressing relative voltage measure-
ments.
There is no zero control but instead a balancing control
allows residual indications due to noise to be minimized resulting
in excellent stability and ease of reading even on the most
sensitive range.
