Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings.
[0024] The precise double temperature correction method of electronic load of the present invention comprises the following steps:
[0025] A. Measure the current actual ambient temperature value through the ambient temperature measurement module, and then compare the actual ambient temperature value with the temperature calibration value stored in the operation processing unit in advance to obtain the actual ambient temperature value and the temperature calibration value the temperature difference between
[0026] B. Obtain the reference voltage value under the current ambient temperature by measuring with the measuring circuit, and then calculate the reference voltage value and the temperature difference obtained in step A through the operation processing unit to obtain the reference correction value under the current ambient temperature;
[0027] C. Measure the loa...
