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 U<10V or
I<10A) or if the frequency is less than 5Hz, the device cannot determine
the frequency and displays dashes "----".

Specific characteristics in MAX/MIN mode

(from 10Hz to 1kHz):

•

Uncertainties: add 1% R to the values of the table above.

•

Capture time of the extrema: approximately 100ms.
