The BC-535 cap test circuit is internally calibrated at the factory and there are no external user controls.

Limited calibration of the circuit can be made, however, via an internal adjustment. The frequency of the triangular wave is fixed in hardware at 100 Hz. There is, however, a trim pot on the circuit board available to adjust the amplitude of the waveform.

If a significantly different waveform is desired , then we suggest using the command-in circuit for this purpose.
