ABSTRACT:
A calibration circuit and method for use with systems of the type displaying values of a measured condition in response to electrical pulses received at the system input in which the repetition rate of the received pulses is representative of the value of the measured condition. Electrical pulses, having a known repetition rate are generated for simulating a value of the measured condition in response to a reference signal of known frequency, the repetition rate of said simulating pulses being determined by the frequency of the reference signal.
