Classification: CPC E  G | IPC E  G

Claim 0:
1. A method for calibrating a downhole tool, comprising:
disposing the downhole tool in a borehole, wherein the downhole tool comprises a first device and a second device;
transmitting a signal from a master module disposed on the first device to a module disposed on the second device;
transmitting a return signal from the module to the master module
determining Tdd of a time for the signal to travel from the master module to the module, wherein the Tdd=(Counter-Tf-T4-T3)/2, wherein the Counter is a second time for the signal to travel from the master module to the module and back to the master module as measured by the master module, the T4 is a master module signal detection time, the Tf is a fixed time delay and the T3 is a module signal detection time;
determining T2, wherein the T2=T3+(Tdd-T1), wherein the T2 is a time delay and the T1 is a time it takes for the signal to be transmitted and detected at the master module;
receiving the return signal with the master module; and
measuring the time for the signal to travel from the master module to the module.
