Continous Integration Mode (Repeat Integration)
• Integration starts:
• after having pressed the START key;
• when the elapsed integration time is reached to preset time, the integrated value
and elapsed integration time are reset automatically and restarted immediately.
• Integration stops:
• when the elapsed integration time is reached to preset time; however, the
integrated value and elapsed integration time are reset automatically and restarted
immediately;
• after having pressed the STOP key;
• when the integrated value reaches the maximum value 999999 MWh/MAh, or
when the integrated value drops to the minimum value –99999 MWh/MAh;
• Integration holds: the elapsed integration time and integrated values at the point
where they reached the maximum/minimum or at the point where the STOP key was
pressed will be held until the RESET key is pressed.

vi and ii are instantaneous values of voltage and current.
n is the number of samples.

is the measured current for each display update rate.
N is the number of display updates
Power integration or current integration with the measurement mode set to DC are
integration of instantaneous power or instantaneous current. If the measurement mode
is set to RMS, integration is performed on the measured current on each display update
rate (see section 4.13)
Note
If you stop integration, the integration process stops at the integrated value and elapsed
integration time of the previous display update. The measured values between the previous
display update and the execution of the integration stop are not integrated.
