Time for which the signal at the digital output is "high". The minimum pulse length is
30 ms and the maximum 500 ms.
● Turn-off time:
Time for which the signal at the digital output is "low". The turn-off time depends on the
measured energy, for example, and can be days or months.
● Minimum turn-off time:
The minimum turn-off time corresponds to the programmed pulse length. 30 ms is the
absolute minimum.
