Note (1) In MAX/MIN mode, the operating range is limited to 1kHz.
If the level of the signal is too low (<10% of the range, or V<10V or
I<10A) or if the frequency is less than 5Hz, the device cannot
determine the frequency and displays "----".
Specific Specifications in MAX/MIN mode (from 10Hz to 1kHz):

Accuracy: add 1% R to the values of the table above.

Capture of the extreme: approximately 100ms.
