MP V3 - Settings for the RGB meter

The discrimination setting of the V3 is not to be set by the numbers on the scale, but by the targets you wish to ignore.

On the V3 the low conductors can not be excluded from the LED meter readings, but they will give a low tone on the VCO as Iron if appropriate setting is used. If you set the discrimination level high enough the low conductors will sound as Iron on the VCO, while on LED meter will be indicated as red color. Iron will never show on the LED meter if the discrimination level is set correctly. If the discrimination level is too low the Iron will show as red color. The medium will show as orange/yellow. The high conductors as white. Both medium and high conductors will sound with high tone on the VCO.
