integration time may cause the 66203/66204 DSP calculation and measurement incorrect if
the A/D converter sampling data is ignored during range change. Thus, the voltage and
current range will be locked when the trigger key is pressed to start the energy calculation.
The range change can only be accepted when the measurement is stopped. When the
UUT’s voltage or current peak exceeds the measurement range upper limit, the 66203/66204
will prompt a warning message and stop measuring. However, it will not prompt an error
message and stop the measurement if the signal peak is temporary. When performing the
energy measurement, only the range and function setup status at present can be viewed as
the range or function change could affect the accuracy of measured value.
