Abstract
A downhole load cell calibrated for enhanced accuracy. The load cell may be a dry load cell calibrated by storage of pre-determined temperature and pressure data relative to the load cell based on known loads applied thereto. Thus, surface equipment employed with the load cell may include a computer program that takes advantage of the stored pre-determined information. The computer program may then be employed for calibration of downhole load cell data based on readings from the load cell along with downhole temperature and pressure information.
