Nexus Standard MP V3 RGB Meter Responses 

You should reread the manual. you have set the lc-mc set knob too high. By doing this you have moved the reading limit of the RGB LED. LC-MC SET control This rotary control is used to turn on/off the RGB meter and/or to set the cut off point between low conductors and medium conductors. For example in some cases hammered gold coins may be preferable to be set on the meter as low conductors (despite that normally they can read as medium-low conductors), so that all other targets can be ignored without potential loss of hammered silver and hammered gold coins. This type of setting will be useful on sites littered with useless non-ferrous targets with conductivity higher than the desired small gold and hammered silver coins.
