A technique for correcting the temperature drift in the measurements of the geophysical instrument of ground-based induction frequency sounding has been developed. The device is considered as a measure of the apparent electrical resistivity of the conducting half-space. In the process of manufacturing the equipment, the temperature coefficient of resistance (TCR) of the device is experimentally measured for each frequency separately. The TCR of the device is used to bring the measured resistance values to a certain normalized temperature, for example, 20 °C. The results of the tests performed were processed and systematized using Microsoft Excel. The graphs of the dependence of resistance on temperature are built. The developed methods are intended to improve the accuracy of data processing obtained with the help of equipment operating under conditions of changing ambient temperatures.
