1) See the typical curve of the 300Hz filter.
2) The LCD indicates “+OL” above +620V, “-OL” below -620V or above 620VRMS.
3) From 1kHz, the measurement must exceed 15% of the range.

The pass band is reduced to 300Hz if the filter is activated. The frequency
measurement is made like the measurement in a 300Hz pass band.
