Note (1) If one of the terms in the calculation of the DPF is displayed as "OL", or
forced to zero, the display of the DPF is an indeterminate value "----".

Note (3) Measurement stabilization ~8 sec
NOTE: The DPF is always positive.

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<8V or
I<9A) or if the frequency is less than 5Hz, the device cannot
determine the frequency and displays "----".
