Information
MODEL
BF-50 CAPACITOR ANALYZER quickly and accurately
measures all the important characteristics of all types of
capacitors. It detects defective capacitors such as open and
short-circuited, intermittent operation, High ans low
capacity, high leakage and power factor of electrolytic
capacitors, and paper or mica”capacitors with low insulation
resistance. It may also be used to measure the capacity
between wires and cables, shielded_ wire, circuit
continuity, and insulation resistance between coil windings,
insulation, etc.
Capacity and power factor measurements are made on a Wien
bridge which is connected to an amplifier for high
sensitivity adjustment. The balance condition of the bridge
is indicated by a visual eye detector. The measurements are
independent of line voltage variation and can be made with
far greater accuracy than most meter type instruments.
Leakage and insulation resistance measurements are made by
means of an adjustable D. C. power supply with the visual
eye indicating the degree of quality of the capacitor under
test.
A 12A7 tube is used as a rectifier and amplifier, and a 6E5
eye tube is used for the bridge detector and leakage indicator.
