11.1.2.4 Measurement channel overview
X = always present
Xi = present if current is measured
Xt = present of the associated trigger was activated
O = able to be switched on/ off (Optional)
- = not present
Bold and italic entries are required for the EN 50160.
Measurement intervals: the interval written in bold print is to be used for compliance with the standard EN 50160.
For all channels, it’s possible to calculate a histogram and the cumulative frequency subsequently.
