Patent ID: 8270248

Claim:
A method for initializing the input of each of m receiver channels of a receiving transducer in a well logging tool disposed downhole comprising the steps of: selecting a logging tool coupled to a control system and having a multi-element receiving transducer and a non-transitory memory wherein each element of the multi-element receiving transducer operates in an anti-resonant mode below its resonant frequency under control of the tool control system; setting a jumper in the logging tool to enter an initialization mode; disabling application of firing signals to a transmitter transducer in the logging tool; running a predetermined number Q of run cycles in the logging tool to determine an average output signal value K and storing the resulting value K in the memory, for each of the m receiver channels; determining whether the average value is within an acceptable range; and repeating the foregoing steps until the averaged reference value is stored for all m receiver channels.
