Abstract
A method of calibrating a well pumpoff controller by calibrating the controller for determining the average load during a pumping stroke, measuring the actual load and averaging the measured maximum and minimum load during each operational stroke, comparing the average measured load with the calibrated average load and providing an offset to the load measurement to correct the measured load towards the calibrated load.
