◆ minRangeFunc

quint8(* DsoCommand::minRangeFunc) (const PokitProduct product, const quint32 maxValue)

inlineprivate

Pointer to function for converting rangeOptionValue to a Pokit device's range enumerator.

This function pointer is assigned during the command line parsing, but is not invoked until after the device's services are discovere, because prior to that discovery, we don't know which product (Meter vs Pro vs Clamp, etc) we're talking to and thus which enumerator list to be using.

If the current mode does not support ranges (eg diode, and continuity modes), then this member will be nullptr.
